The external dimension is 69.2x122.2x23.4mm (width x depth x height), weighs about 230g, which is small among portable amplifiers.This size is particularly attractive with a balance -driven model.
The design is "black square box" and is sober, good or bad.Some people may not want to claim the amplifier too much, or those who are good at this "ruggedness".I personally want a little more design.However, the housing and volume knobs are made of metal, so the texture is high when touched.
REX-KEB02iP側面天面There are plenty of partners who can cooperate.It has a "USB DAC mode", which is broadly divided into Windows/Mac, and an "iPod compatible mode" that regenerates digital audio outputs from iPhone or iPod connected with LignTning-USB cable or 30Pin-USB cable.
As mentioned above, in USB DAC mode, PCM up to 384kHz/24bit, 5.6/2.It also supports 8MHz DSD files and also supports DSD native playback (DOP).In fact, when I connected to a PC of Windows 7 and played the PCM or DSD high -resolution file using FOOBAR2000, a sound came out without any problems.
There is no display, but there is an indicator on the back, and if you receive PCM data, it will glow red if it is DSD data.
USB B terminal is for PC connection.The USB A terminal at the left end is for iPod connection.If you connect to the iPhone with the LignTning-USB cable or a 30pin-USB cable, it will play up to 48kHz/16bit.When playing high -resolution data from the iPhone, it is necessary to connect to the input terminal for the PC via the camera connection kit described later.
通常のDockケーブルでiPhoneと繋いだところカメラコネクションキットとHF Prayerなどを組み合わせれば、iPhoneからハイレゾ再生も可能PCと接続してUSB DACとしても動作するWe have an iPhone that installed onkyo's high -resolution playback application "HF PRAYER".When I connected the amplifier with the amplifier via the camera connection kit, played a 192kHz/24bit PCM and a DSD file, a sound came out without any problems.It is an image that uses iPhone+HF Prayer instead of a PC, and it is important to note that high -resolution playback cannot be performed with the standard music app on the iPhone.
背面端子部インジケーターのカラーでPCMやDSDが判別できるIn addition, it supports the connection with the Walkman.Walkman has a high-resolution audio output cable "WMC-NWH10" as a peripheral device.By connecting to NW-F880 via this cable, it can be transmitted to DAC with digital data.REX-KEB02IP made a clear sound.
ウォークマン用ハイレゾオーディオ出力ケーブル「WMC-NWH10」を使って、組み合わせたところプレーヤーとアンプを固定するゴムバンドも付属しているIn addition, switching between USB DAC mode and iPod mode is performed on the back switch, but in USB DAC mode, "USB-BP mode" which is powered by bus power and "USB-BT mode" that operates with a built-in battery.It is done.
Both USB-BP mode and USB-BT mode can be used when connecting to a personal computer.Use USB-BT mode when using the iPad+camera connection kit or a Walkman high-resolution output USB cable.
The DAC uses ESS "ES9018K2M".It features a master clock from a high -speed clock (80MHz) and removes jitter of audio input by reclocking.In addition, two independent high -precision crystal os long (22) inside (22).5792MHz/24.Equipped with 576MHz).The data entered from the USB is converted to an I2S signal and supplied to the DAC section.
There is also a digital filter switching switch for "ES9018K2M".The user can change the setting of the sharp/slow according to your preference.
