CONFIG GUIDE - VENUS DAC

Basic Operation

I2S Pinout Configuration

1. Select I2S Input

2. Press the Mute button once to enter configuration mode

3. Press the Phase button momentarily, 1X 2X 4X will turn on/off in a fixed pattern to denote binary 000-111​

4. Wait for 10s

5. DAC back in operational mode

​

​

Suggestion of I2S Matching with the source, i.e. DDC/Transport/Streamer

​

1. Connect the I2s cable
2. Turn down the volume (minimal)
3. Play a familiar music (PCM first, followed by DSD)
4. Run through the i2s setting of the DAC, 000-111
5. One of the modes should match with the source for both PCM and DSD playback.


It's recommended to go through the Audio Tone Test to make sure the L/R channel, in phase/out of phase correctness.

I2S DSD Channel Swap Configuration


1. Select I2S Input
2. Press the Mute button once to enter configuration mode
3. Toggle the NOS button
- CO1 On = DSD Channel Swap
- CO2 On = Normal
4. Wait for 10s
5. DAC back in operational mode

Filter Selection (Effective in OS Only)

1. Press the Mute button once to enter configuration mode

2. Press the Mode momentarily

  • OPT LED On = Slow Filter

  • OPT LED Off = Sharp Filter

3. Wait for 10s

4. DAC back in operational mode

Dual AES/EBU Input

1. Press the Mute button once to enter configuration mode

2. Press the INPUT+ momentarily, CO1, CO2 LED will turn on/off

  • CO1 On = Dual AES/EBU Input Enabled

  • CO2 Off = Dual AES/EBU Input Disabled

3. Wait for 10s

4. DAC back in operational mode

Yours Sincerely,

I2S DSD Channel Swap Configuration

1.Select I2S input  
2.Press the sound button once to enter configuration mode  
3.Toggle the NOS button    COAX light represents L/R    AES1 light represents R/L  
4.Wait for 10 seconds  5.DAC returns to operation mode

Filter Function Settings

1.Press the MUTE button to enter menu mode, then press the MODE button
to enter filter function settings  (Press MUTE + MODE buttons) → 8x Light on.

2. Press INPUT- again in the Clock Output Function Settings:  
- CLOCK OUT light on + COAX light on:    Outputs a word clock with the same sampling rate as the  input signal;    
- CLOCK OUT light on + AES1 light on:     Outputs a word clock;    
- CLOCK OUT light on + AES2 light on:     Outputs half of the master clock;    
- CLOCK OUT light on + OPT light on:       Outputs the master clock.
