1、 Good audiovisual needs good speakers

Recently, a friend was renovating a house. This house has spent almost all his savings, and has also been burdened with loans for decades. Naturally, he was very careful in renovating it. From switches and hinges to tiles, furniture and household appliances, he repeatedly screened and compared them to ensure high quality, high beauty and high cost performance. At the end of the house decoration, the author went to visit the new house, which cost a lot of money. The new house is very beautiful, especially the audio-visual equipment. A large size curved TV is placed in front of the beautiful and exquisite TV background wall. The visual effect is very good, but the author has some complaints about his matching stereo.

My friend didn't know much about audio. When buying a TV, he was strongly recommended by the shopping guide to configure a set of domestic audio for more than 1000 yuan, and then bought a speaker of a foreign brand at the same price. However, the author's feeling is that the home-made sound system is too ugly and does not match TV at all. As for the sound quality, the shocking bass is very pleasing to some consumers. However, the author sounds mixed and has poor permeability. There is also the big foreign brand speaker, which has a good appearance, but is not cost-effective, and the sound quality is satisfactory.

Speaking of speakers, the author recently just got a favorite speaker, called the Pacer MA5.

Edifier/Pacer MA5 smart cloud speakers, the official flagship store of Tmall, is currently selling at 1199. Interested friends can check it with the author.

2、 Look at the product

When talking about Pacers, I believe many friends are not unfamiliar with this brand. I remember that when I was at school, some friends in my class used Pacers' speakers or MP3 players. As time goes by, Rambler has grown rapidly since its establishment in 1996, and has gradually become a top speaker brand in China. It is also highly praised internationally and has won many international honors, which can be said to be the pride of China's own brand. The author is very pleased to get the MA5 newly launched by Rambler.

▲ When I first got the product, the author was really shocked. It was such a big box. The author has used several smart cloud speakers, which are generally small in size. With the MA5 as large as its body, it seems that its mentality is obviously higher.

Delicacy is a gift box, and there is not much front introduction. The three logos of Bluetooth, optical fiber, and wifi, as well as the two-dimension code of Alibaba Smart APP, indicate that the MA5 is fundamentally different from traditional speakers, and basically covers the latest popular functions of smart speakers.

▲ The packaging box is mainly divided into two parts, the main body of the sound box covered by foam plastic and the product accessories in the kraft paper box. In addition to foam plastic, the MA5 is also protected by a white cloth bag. It is a reminder that this cloth bag is only for protection, and cannot be used as a handbag of the MA5.

▲ Come to see the numerous family members in the MA5 family photo: speaker body, product manual, after-sales service card, remote control, wiping cloth, power adapter, power cable, optical cable, AUX cable. The abundant logistics support group is ready to provide hardware support for the powerful and diverse functions of MA5 at any time. According to the information on the official website, this product is divided into black version and red version according to the color. It is obvious that the red version was obtained by the author.

▲ The streamlined infrared remote control is very compact and round, with a built-in cr2025 button battery. The main body of the remote control is silver white. Several keys are arranged in a pyramid shape. On/off keys are set at the upper end. Five keys in the middle are volume+/-, up/next song, and music pause/play. Three keys are set at the bottom row, which are Bluetooth, wifi, OPT (optical fiber)/AUX switch keys. The key arrangement is ergonomic and easy to operate. With it, various functions can be switched wirelessly and conveniently.

The author has some opinions about this remote control. For mass consumers, Bluetooth, wifi and AUX are the most commonly used signal sources. However, when the remote control presses the OPT/AUX key, the first switch is OPT, and the second press is AUX. Such commonly used functions are ranked behind. I don't know how the designer considered them.

▲ The size of the power adapter is a bit large, and the output is 20V/2.75A. It seems that the operating power of this speaker is not small.

▲ The appearance of MA5 adopts a very sci-fi color, which is similar to an ellipsoid that has been cut open, and the workmanship is extremely exquisite. The red part uses brilliant piano baking paint, and the "section" is sprayed with black rubber fiber matt paint, which has a very good feel. The main body weighs about 3.5kg, and it is hard to lift it with one hand.

When I see MA5, I often think of a TV play I saw as a child, called "Dinosaur Battalion", in which there is a cute little robot called Alpha. I always think that MA5 is very similar to this alpha. I wonder if any friends have seen this play.

▲ The black area at the "section" is the main functional area of the speaker. Two 3-inch concave embossed PP basin subwoofers, like two big eyes, are set in the most prominent position. Two 19mm silk film dome tweeters are arranged on both sides, together with four built-in 3-inch passive units. Through the intelligent electronic frequency divider, various generating units cooperate with each other to achieve smooth conversion of high and low frequencies, Jointly create the shocking sound effect of MA5. There is a round LED display screen in the middle upper part of the two subwoofers to display the operating status of the speakers in real time. A protective ring is set outside each of the two tweeters to prevent the diaphragm from being damaged by external forces.

▲ The top of MA5 is the control area of the speaker, and 10 capacitive touch keys are set on it in two rows. There are a lot of buttons, and there are too many speaker functions. Through these 10 touch keys, the speaker can be turned on/off, signal source switching, network search connection, program collection, voice search, volume -/+, previous/next song play, play/pause and other functions.

▲ The main information of the product is marked in the middle of the anti-skid rubber gasket at the bottom. The two QR codes are Alibaba Smart APP download address and the rambler WeChat official account. A few days after the author used the MA5, a slight "bulge" appeared on the rubber gasket, which should not be.

Power input interface, optical fiber signal interface and AUX signal interface are set on the back of the speaker. The author always believes that this optical fiber interface is a chicken bone function, because there are few players supporting optical fiber output in the market at present.

▲ The appearance of MA5 is sci-fi. If you don't see several sound units, it's hard to think of it as a sound box. It has a high face value in many directions and a sense of art. Whether it is placed on the table, tea table or display rack, it always exudes mysterious meaning.

▲ The MA5, full of the sense of technology and fashion, lies quietly on the head of the bed, and has some cute and cute appearance.

▲ Just because I looked at you more in the "speaker group", I never forgot your face

3、 Try the function

▲ The author will not discuss the operation of the remote control in detail. The basic functions of the remote control have been described in the previous article. The author can't understand the switch of MA5. The machine operation, the switch on key and the signal switch key are combined into one. It is understandable to press the signal switch for a short time and press the switch on and off for a long time. However, if the machine is switched on and off by the remote control, it is to press the power key of the remote control for a long time, and press the power key for a short time without setting other functions. The author wondered why the remote control is set to press long rather than short for the two functions that are used so frequently? In addition, when the power supply is connected when the machine is turned off, the MA5 will start automatically.

▲ BT, Wi Fi, OPT and AUX displayed on the upper left corner of the LED display screen represent the four different signal source playing modes of MA5. In the middle of the display screen, the radio station name and program name are displayed in Wi Fi mode, and the volume is displayed in other modes.

The sound level of MA5 is 0-60. The sound quality evaluation data shows that 80-90dB sound pressure level is the most beautiful and pleasant for human hearing when playing music. Corresponding to MA5, the volume can be adjusted to 30-40 when it is about one meter away. If the volume is larger, the surging energy can be heard very clearly in a house of more than 100 square meters, It is basically no problem to dance square dance.

▲ Alibaba Smart and JD Microlink, which can be said to be the two most important integrated connected apps for smart home, have collected a large number of smart home products, one-stop operation, collaborative management, and convenience. MA5 chose to join the Alibaba smart camp.

Open Alibaba Smart APP and find the rambler MA5 connection. APP covers a lot of resources, mainly including Xiami Music, Douban FM, Himalayan FM and Dragonfly FM. Each station has a huge amount of resources, including music albums, consulting gossip, astronomy and geography, ancient and modern, Chinese and foreign, and novel crosstalk. Naturally, the radio stations I like are also very comprehensive.

When the speaker and mobile phone are in the same WIFI state, MA5 can play the resources provided by the service providers covered by the APP, and also support the use of DLNA protocol to connect with mobile phone apps that also support related protocols, such as Baidu Music, NetEase Cloud Music and other APPs, and also can connect with computers in the same network wirelessly to play related resources.

Many friends may know about infrared, Bluetooth and WIFI connections, but they don't know much about DLNA. In fact, DLNA has been born for more than ten years. It is a technical solution developed to solve the interconnection between wireless networks and wired networks, including personal PCs, consumer appliances, and mobile devices. According to the author's brief use experience, DLNA has many connection steps, slow response, and instability, so it is basically not used at ordinary times. I believe this is one of the reasons why DLNA has not been widely used.

For Bluetooth, AUX or optical fiber connection, I don't believe the author needs to introduce too much. It is similar to many audio devices, that is, connect with mobile phones, computers or other devices through Bluetooth or audio cables, and play the audio in them.

For many smart products on the market, voice function seems to have become a standard configuration. Since MA5 can be called an intelligent cloud speaker, this function is essential.

▲ In the WIFI mode, touch the voice key on the top of the speaker. As long as you say the name or category of the music you want to listen to, you can automatically search. For example, commands such as "wind blowing north", "pop music", "rock", etc., MA5 can receive commands to complete the search and play task.

I still think this function is a chicken bone, just like the voice assistant that is pre installed on most mobile phones. No matter whether it is good or not, I have never seen a friend who is accustomed to using this function. Similarly, when using MA5, the author's habit is that if he wants to listen to a certain music, he usually searches for resources by connecting his mobile phone or computer. In addition, MA5's voice recognition ability is not high. I feel that it is good to recognize half of it.

One detail of MA5 is very good. Friends who have used Bluetooth speakers should know that when many Bluetooth speakers play music, once a call comes, the voice of the call will be played through the Bluetooth speakers. The author used to cut off Bluetooth before he dared to connect the call. Using MA5 can completely avoid this embarrassment. When the call is made under the same status, MA5 will automatically enter the pause playing status, which will not affect the phone call at all, nor will it enter the "live broadcast". When the call is over, click the play button to resume the music playing.

On the whole, MA5 is very powerful, WIFI、 Bluetooth, optical fiber, AUX plus DLNA, as well as voice search function, can be played independently on computers, mobile phones, or through the network. The diversified control methods ensure that it can be applied to all kinds of scenes, whether in the home or business environment, everywhere is his arena.

4、 Listen to the voice

Different speakers will have their own music performance style. The same music is played by different speakers. If you listen carefully, there will be some subtle differences, such as "British voice", "American voice" and "German voice" of speakers. "British Voice" has soft and delicate timbre and rich musical sense, and has excellent performance in classical music. "American Voice" pays more attention to momentum, strength and atmosphere creation, which is more suitable for playing pop music or as a home theater, while "German Voice" pays more attention to the true restoration of sound, and its characteristics are between the first two.

▲ During the audio test, the author uses the Bluetooth playing mode. Meav's One I love is a soundtrack frequently used by the author. The first minute and 15 seconds are the solo part. Meav's singing voice is transparent and ethereal, which can well test the high frequency of the speaker and the expressive force of the voice. MA5 is not strong in vocal performance. Its voice is mellow but lacks brightness, and its transparency is not high. Later, it continued to listen to Vinia's "If Clouds Know" and Liu Lianglu's "Past Like the Past", with similar effects. For another style, try the Hawks' California Hotel. In this audition, MA5's voice was powerful and powerful, with good analytical power and strong transient response ability, and the scene atmosphere was very vivid. The author also listened to a few rock pop music at random. As we all know, most of such music pays more attention to the interpretation of bass and rhythm. At this time, MA5 releases huge energy, especially the strength of the bass part. The effect is strong, the overall rhythm response is sensitive, and the sense of hierarchy is very good. The atmosphere of full impact is not like that created by this small speaker.

Personally, MA5 is more inclined to be good at playing the "American Voice" of modern rock and roll pop music or movie music. It is characterized by shock bass, rapid response, impact and good at creating atmosphere.

▲ The person who lives meaningfully is not the person who lives the most in his years, but the person who feels the most about life. When I am alone, I like to sit in front of the workbench and listen to music with MA5, or connect the computer and TV to play movies, so that my thoughts can flow freely with the waves of music, or be tense, exciting, or relaxing, sinking in the charm of the sea of sound.

5、 Make a summary

I felt a lot during the use of MA5. I accidentally wrote it for such a long time, so let's make a summary.

Let's start with the appearance. The MA5 has a unique shape, soft lines, exquisite modeling, and a very sci-fi shape that seems to come from outer space, which is very artistic. As a smart cloud speaker at the forefront of science and technology, MA5 also has special functions under its special shape. Multiple signal sources can be switched at will, which can be remotely controlled, wireless, voice operated, and connected to mobile phones PC， It can also play resources independently online, and can easily cope with a variety of environments. As the top speaker brand in China, the sound quality of Pacer MA5 is also outstanding. Its small size has explosive energy, which is very suitable for home use.

The advantages often coexist with disadvantages, and MA5 is no exception, such as the "bulge" phenomenon of the base rubber pad, the non artificial automatic startup when the power is turned on, the incomprehensible startup and shutdown mode, the voice function with extremely poor recognition ability, and the OPT/AUX switch of the remote controller. I hope these problems can be improved.
