5. Setting POWER MODE 

 
CDA-4D can be set up to automatically power on 
when needed. The POWER MODE can be selected 
via the Product Configuration Page, allowing the 
CDA-4D to be powered on at all times when 
POWER MODE is set to ON. The CDA-4D can also 
be turned on when an audio signal is present at any 
audio input by selecting AUTO DETECT or the 
12V TRIGGER.

To set up CDA-4D to be controlled 
by a 12V trigger:

 

 
  1.  Connect the 12V trigger cable to the 3.5mm 
    12V TRIGGER IN socket, see 

Diagram 11.

 

    Ensure a 12V signal is present.

  2.  Select 12V TRIGGER in the 
    POWER MODE settings

  3.  (Optional) Connect the 12V TRIGGER OUT 
    socket to a 12V TRIGGER IN on another 
    amplifier to link the power control together

In this mode, CDA-4D will turn on when a 12V signal 
is present on the 12V Trigger Input. This 12V trigger 
input can be wired to the 12V trigger output from an 
audio matrix switch or a relay.

Note: 

All amplifier zones turn on when a 12V 

trigger is received in 12V TRIGGER MODE.

6. Network Connection Instruction 

 

6.1 Connecting to your Product 
Configuration Page 

 
  1.  The amplifier’s factory default settings 
    has DHCP set to ON.

  2.  Connect the amplifier to a network with a 
    router using a RJ-45 cable. Make sure the 
    computer / tablet and amplifier are on the 
    same network.

  3.  Turn on the amplifier.

  4.  Open a web browser

  5.  Enter the CDA-4D default network address 
    [product name]+[serial number] for example: 
    http://cda-4d_XXXX-xxxxxxx.local in the  
    browser address field and press “return”. This  
    will open the Product Configuration Page.

Alternatively, all network IP addresses will be 
accessible from your Router configuration page.
