The CEntrance HiFi-M8 24-Bit 192 kHz Portable DAC Amp (4-Pin XLR, 1/4" TRS, 1/8" TRS) is designed for portable and desktop HiFi audiophile listening. The unit enables you to bypass your computer, iPhone, iPod, or iPad's internal digital to analog converter, and instead utilize the device's dedicated dual core XMOS microprocessor as a USB DAC and iPhone dock. You can connect one pair of balanced headphones using the 4-pin XLR output, one pair of unbalanced headphones using the 1/4" TRS output, and one pair of unbalanced headphones using the 1/8" TRS output. The 1/8" TRS output also doubles as a digital SPDIF input for connecting to devices with a digital out, such as some video game consoles and portable media players.
The device includes controls for adjusting 3 levels of impedance for different kinds of headphones, 3 levels of gain, 3 levels of bass boost, 3 levels of treble boost, and a volume knob. You can operate the unit using an external power supply or using its internal lithium-polymer battery with approximately 5-7 hours of run time. You can also use the device to charge your iPhone or tablet while playing when plugged into the external power supply.
