1.  Power Connector 

Connect the included IEC power cord to this connector and the other end to an available AC outlet. 

2.  USB Connector 

This connector is used for updating the firmware in the AFS2 from a connected computer. As firmware updates become 
available, they will be found on the AFS2 product page at dbxpro.com.

3.  Output Connectors 

Two types of balanced output connectors are provided for output connections: male XLR type connectors and 1/4" 
tip-ring-sleeve phone connectors. 

4.  Input Connectors 

Two types of balanced input connectors are provided for input connections: female locking XLR type connectors and 
1/4" tip-ring-sleeve phone connectors. Either of these input connector types can be used with balanced or unbalanced 
connections. The maximum input level that the processor can accept is +20 dBu (ref: 0.775 Vrms).

5.  Operating Level Switches 

These switches allow you to select between a nominal operating level of 4 dBu or -10 dBV for each channel. 
Use these switches to match the operating level of the AFS2 to the interconnecting equipment. 

NOTE: 

The +4 dBu/-10 dBV switch on the back panel of the AFS2 must be set to the correct position for your 

application in order to avoid performance issues. +4 dBu is referred to as ‘pro level’ and will be the correct setting for 
most applications, as most pro and semi-pro mixers will output a nominal level of 4 dBu. -10 dBV is referred 
to as ‘consumer level’ and will need to be used when connecting a device which has an output level approximately 12 
dB lower than pro level equipment. If you’re unsure of the nominal operating level of your device’s connections, take a 
look at the device’s manual or contact the device manufacturer.
