1. Go to www.ATIaudio.com and register your new ADAC-2. If you need more detailed information than this Quick Start Guide provides, you can download the ADAC-2 User Manual from the on-line Support tab.

2. Connect ADC, DAC and SRC inputs and outputs on rear panel as required.

3. Connect 120VAC, 60Hz power to IEC320 inlet on rear panel using the line cord provided.

4. Switch power “ON” using AC mains switch on rear panel.

5. ADAC-2 can run in all three conversion modes simultaneously.

Use ADAC MODE switch to control and display ADC, DAC or SRC mode on front panel. Settings are stored for each mode.

NOTE - To lock/unlock front panel in any ADAC mode, press and hold MUTE

button. Press UP to lock, DN to unlock, then release MUTE. ADAC MODE LED flashes to indicate panel lock.

ADC Front Panel Mode

• ANALOG INPUT SELECT chooses XLR (Balanced) or RCA (Unbalanced) inputs

• DIGITAL INPUT SELECT has no function in ADC mode

• SAMPLE RATE SELECT chooses and displays ADC sampling rate, native up to 96kHz

• SRC WORD LENGTH SELECT has no function in ADC mode - ADC output is always 24-bit

• DIGITAL ERRORS has no function in ADC mode

• ANALOG LEVEL LED meter shows peak level of conversion result relative to 0dBFS;

Red LEDs indicate overload condition

• GAIN UP/DN adjusts ADC input gain; UP increases gain—each step is 0.5dB At default setting, +18dBU (Balanced) or +4dBV (Unbalanced) input yields 0dBFS output

• MUTE silences ADC and headphone outputs and blanks Analog Level meter

• SIGNAL MONITOR: LOCKED indicates active analog input signal; MUTED indicates ADC

output status; PRO MODE indicates output signal status bits selection (Consumer or Pro); cycle input selection to change output mode

• EXT SYNC enables ADC external sync mode, provided EXT SYNC input is present and LOCKED LED is on

• HEADPHONES provides monitoring for ADC input

• GAIN UP/DN adjusts headphone volume level

DAC Front Panel Mode

• ANALOG INPUT SELECT has no function in DAC mode

• DIGITAL INPUT SELECT chooses one of four digital inputs or output of SRC (SRC DIRECT) as

input to DAC

• SAMPLE RATE SELECT has no function in DAC mode; LEDs display sample rate of DAC input signal

• SRC WORD LENGTH SELECT has no function in DAC mode; LEDs display word length of DAC input signal

• DIGITAL ERRORS LEDs indicate specific errors in DAC input signal

• ANALOG LEVEL LED meter shows peak level of conversion result relative to +4dBU at

balanced analog output jacks

• GAIN UP/DN adjusts DAC input gain; UP increases gain—each step is 0.5dB At default setting, -14dBFS input yields +4dBU (Balanced) or -10dBV (Unbalanced) output

• MUTE silences DAC and headphone outputs and blanks Analog Level meter

• SIGNAL MONITOR: LOCKED indicates active digital input signal; MUTED indicates DAC output

status; PRO MODE indicates input signal status bits (Consumer or Pro)

• EXT SYNC has no function in DAC mode

• HEADPHONES provides monitoring for DAC input

• GAIN UP/DN adjusts headphone volume level

SRC Front Panel Mode

• ANALOG INPUT SELECT has no function in SRC mode

• DIGITAL INPUT SELECT chooses one of four digital inputs or output of ADC (SRC DIRECT) as

input to SRC

• SAMPLE RATE SELECT chooses SRC output sample rate; LEDs display selection

• SRC WORD LENGTH SELECT chooses SRC output data length; LEDs display selection

• DIGITAL ERRORS LEDs indicate specific errors in SRC input signal

• ANALOG LEVEL LED meter shows SRC output attenuation relative to 0dB; minimum setting is

-45dB; default and maximum settings are 0dB (no attenuation)

• GAIN UP/DN adjusts SRC output level; UP increases level—steps are 5 or 10dB, as indicated

• MUTE silences SRC output

• SIGNAL MONITOR: LOCKED indicates active digital input signal; MUTED indicates SRC output

status; PRO MODE indicates output signal status bits (Consumer or Pro), cycle input selection to change output mode

• EXT SYNC enables SRC external sync mode, provided EXT SYNC input is present and LOCKED LED is on

• HEADPHONES have no output in SRC mode

• GAIN UP/DN are not used in this mode
