The A100 BT5.0 "A100 BT5.0" is attractive in the air pulse -built -in -built -in active speaker.

　Air Pulse A100 BT5.0 (A100) is a speaker system that was impressive when reviewed in Stereo Sound magazine No. 218, and in the previous issue of this magazine, Ryuki Ito is a review of the wonderful abilities of this unit.。So, in this issue, I focused on the multi -per -pass abilities of A100, which is more functional than the excellent powered speaker, and digs the charm of A100 from a multifaceted.

　If the A100 was designed by Ka no Phil Jones, a veteran audio file would remind you of the small speaker system that was once designed by him and a huge hit worldwide.The A100, which has been transformed into a full digital -consisting active speaker system, is a model that has been released last summer and has been a topic, A80, one size.

　The A100 is equipped with a 127mm aluminum alloy cone and a magnetic circuit with a powerful neodium magnet on the woofer, and has a horn loaded ribonteator with neodium magnet.The amplifier is a full digital configuration equipped with an XMOS processor, with two TIS5754 class D stereo amplifiers on the R side cabinet, one is L / R tweeter, and the other is L.The biper amplifier and bridge connection that drive the wofer of R.

　In the input terminal, two analog RCAs are compatible with two analog RCAs, and the digital input is also used to Bluetooth in addition to the USB type B and light.By the way, BT5 at the end of the model name.0 is Bluetooth 5 that supports AptX decoder.It means 0 mounting, but it can be expected to have more advanced audio performance than general SBC codecs.

(1) Reproduction to the fine environmental sound that can be used in the playback of AV system video works using a thin TV

　Watch in HIVI viewing room.Place A100 on a solid speaker stand, L / R speaker is about 1.A set of 50 inches of LCD display is placed between both speakers, 4m away, between both speakers.The bass / treble adjustment knob on the rear panel of the R side speaker is flat, and the L -side speaker is connected with a dedicated cable.Check each performance by fully utilizing the multifunctional A100 that has analog / digital input and a Bluetooth connection.

　Pioneer UDP-LX800 is connected to the UHD Blue Ray Player, and the CD is played with A100.R + R = NOW, which has a blue no trabel elite with Robert Glasper as a leader, is impressed with the low -frequency growth, but the strength and the strength of the booming.The balance is well -balanced, and the focus is more than expected.

　When I listen to the SACD released in the stereo sound, Barbara's "Chanson for myself", "Rain in Nantes", her voice full of delicate and real feeling emerges between both speakers, and if I reach out, I reach out.The freshness that is likely to be touched by.

　Then watch Blu -ray with LX800.From "John Williams Live in In Vienna", the voice is 2.Select 0ch stereo (96kHz / 24 bits of DTS-HD master audio) and play "Raiders March" by analog connection.A good sound with a well -balanced bandwidth, without emphasizing sound edges overall.Next, if you use an optical digital connection, the sound is slightly lighter than the analog connection.This is because high -spec digital signals of 96kHz / 24 -bit or more are converted to 48kHz / 16 -bit signals when output with light / coaxial.However, there are some BD recorders that cannot output analog, and even in that case, it is a sound that can be enjoyed enough.

　Return to the analog connection and play the UHD Blu -ray "Hell's Apocalypse Final Cut".The scene where play girls fall on the riverside of the jungle of Chapter 9 are included in the sound of rock bands in a really fresh sound.If you play this performance with A100, it will be a bone sound that will not be taller, and even if it is played with a loud sound that matches the 50 -inch video size, the sound of more powerful than expected, including the rotor sound and engine sound of the helicopter.It became.

　The playback of Netflix movies using Apple TV 4K is a choice of "ROMA / Rome", which was impressed by the great image quality sound quality.The HDMI output from the Apple TV 4K is input to the TV, and the sound is output from the TV with optical digital, and in A100.This is an assumed connection method for playing netflix on TV.

　By the way, this work is really wonderful with the environment of environmental sound, but it can be felt quite a bit in 2ch playback, and it can be seen that the environmental sound outside the frame is still small.The A100 was immediately understood that it was a speaker system that was excellent in dialogue, but it would be the excellent nature of Ribonte Eater, and the fine environmental sounds and fuss are wonderful, and thanks to the Mexico City Ichii's Ichii.Plenty of dirty air has been transmitted.

② You can get a high -five sound just by connecting with a desktop system USB with your PC

　Next, the MacBook Air and A100 are connected to the USB to play high -resolution (streaming using QOBUZ this time).Please consider this as a proposal for a desktop system using a PC.

　The melody Gardeau "Sunset in the Blue" (96kHz / 24 -bit / FLAC) is fascinated by the silk mellow sound.The same 96kHz / 24 -bit / FLAC Blue Note All -Stars "Hour Point of View" "Mascarello", which Wayne Shorter and Harvy Hancock participate, will surely be surprised if they listen.Hi -fi sound.The rich and strong Derrick Hodge is very convincing the speaker system made by Phil Jones, a bassist.

　More than 15 years ago, I witnessed a demonstration of a small electric bass amplifier (Phil Jones Bass) in the HIVI viewing room of the Roppongi era.At that time, he played the electric bass in front of him, and he heard the story, and he said, "I started the bass at the age of 13, longing for Motown's legendary bassist James Jamerson."He also said, "Pinot Paradino is an old friend," a modern representative of the first call bassist.Both Gemerson and Paladino are my fabrit bassists.That's why the A100, which was created by a bassist and a genius speaker designer, was very convinced that it would combine outstanding low -frequency playback abilities and the whole area.

　Watching a movie using Netflix on your desktop is a big difference if there is no full -fledged powered speaker like A100.In addition, the sound of USB connection is really wonderful.By the way, even a slightly sober movie such as "ROMA / Rome" is literally a difference in cloud mud, which is no longer comparable to the sound coming out of the built -in laptop.I think many people are watching movies on a notebook PC, but with a spending of 100,000 yen (A100), it will always be heaven.This time I knew it, but if it was an explosive movie like "Ford VS Ferrari", the A100 would be a must.

　Finally, from the smartphone (iPhone) TIDAL at the Bluetooth connection, a tenor saxophonist Joshua Redman's combo plays the excellent recording "SUN ON SAND" co -starring with a string quartet.I didn't lighten the sound of Bluetooth, but I understand that if the original recording was excellent, I could listen to it with a pretty good sound.The sound source was compressed for wireless transmission, but the drums of Japanese percussionist Takeishi Takeshi had a sense of speed, and I enjoyed Joshua's tenor saxophone with a lot of power.

　When used in a conventional AV system, this time it was combined with a 50 -inch LCD TV, but I think there is no problem even on a slightly larger screen.Furthermore, let's promise that you can get a very satisfying result even if you use it as a desktop system combined with a PC.This is a great attraction of A100, which can be widely adapted to the environment and needs of almost all people who purchased this unit.
