Balanced Output Headphone Amplifier Module For X7. The AM3 balanced output headphone amplifier module for the X7 high resolution music player utilizes the newly launched Burr-Brown OPA1622 from Texas Instrument. In total, six OPA1622 chips are incorporated to achieve full stereo 2.5mm TRRS balanced output as well as 3.5mm single-ended output with an ultra-low THD+N of -119.2dB (0.000018%) into a 32 Ohm load at 10 mW output. This level of awe inspiring performance is 12 times better than competing products on the market. A small screw driver is included in the package for working with the two T5 screws holding the amplifier module in place. With the two screws removed, the amplifier module can be unplugged with a firm pull. Installation is the reverse of removal. With this amplifier module installed, the X7 will provide over 6 hours of playback under the following conditions: Screen off, EQ off, low gain, 27 Ohm single-ended load or 16 Ohm balanced load, volume set at 58 for single-ended or 50 for balanced load, playing 44.1kHz/16bit MP3 file. Specs: Power Output: >540mW (32hm @1kHz) - Frequency Response: 5~83kHz - SNR: >115dB (A-weighted) - Output Impedance: < 0.3Ohm - Channel Separation: > 110dB (32Ohm @1kHz) - THD+N: <0.0008% (32Ohm @1kHz) - Peak Voltage: >11 Vp-p - Max Current: >160mA. Color: Titanium.
