8-channel 192kHz/24bit DAC is based on two Asahi KASEI AK4414 dac chips, provides with xVM USB interface complete solution for Home Cinema (up to 7.1) or multi-band stereo (4 bands in 2 channels) and other applications.
8 RCA outputs.
2 scales (44.1x/48x) MCLCK oscillators on board (optionally oscillator types can be used - double frequency Silicon Labs, general FOX and NDK femto clocks).
Slave I2S input bus with Master MCLCK.
Hardware Mute (with 4 signal relays at the outputs)
Interface connector is pin-to-pin compatible with ATDAC-91 and xVM.
Microprocessor based control.
Sharp/slow roll-off filter switch (with indication).
Sample rate indication.
Optional digital volume control (with indication).
Power supply on additional board with voltage monitor, Schottky diodes full wave rectifiers with central tap and snubbers. Full set includes EMI mains filter with DC-cut circuit.
8 voltage regulator used in ATDAC-9 and the power supply, including very low noise TPS7A4700 and TPS7A3001.
No power switch need - device is going after 20min. to sleep mode when there is no valid input signal and immediately wake up if the signal presents. For a long off period, main switch is provided on the back panel.
No cables between ATDAC-9, it's power supply unit and xVM USB interface. The only wires are from the power transformer.
Optional connector for 8-Ch volume control.
Optional slot for ADC module (ATD9ADC).
Optional 10-channel version (additional 2-channel DAC, PCM5102A, into ADC slot). Required xVM-10ch.
