| 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.
