1.  Power Connector 

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

2.  Fuse Drawer

 

This drawer houses the main power fuse as well as a replacement fuse, see 

‘Replacing The Fuse’ on page 27

  

for further information.

3.  Option Card Slot 

This option card slot can be fitted with the 676 Digital Option Card (sold separately) which adds AES and S/PDIF 
digital outputs. The Digital Option Card is equipped with high-quality A/D converters and our proprietary dbx Type IV™ 
conversion system to prevent the A/D converters from accidental clipping.

4.  Compressor Line Output Connectors 

This output carries the signal post-compressor/limiter. Both 1/4” and XLR balanced COMPRESSOR / LIMITER outputs 
are provided. The COMPRESSOR / LIMITER output can be used by itself or along with the Preamp output for parallel 
compression applications, see 

‘Parallel Compression’ on page 18

 for additional information.

5.  Compressor Sidechain Insert Connector 

Connect an insert cable to this unbalanced connector to patch in another device for processing the signal feeding 
the compressor’s detector circuit. For example, an external EQ could be connected and used for frequency-weighted 
compression, such as de-essing. See 

‘Sidechain Application’ on page 21

 for more information on using this 

connector.

6.  Preamp Line Output Connectors 

This output carries the signal post EQ and pre compressor/limiter. It provides a slightly more minimalistic signal path 
than the COMPRESSOR / LIMITER output. Both 1/4” and XLR balanced Preamp outputs are provided. The Preamp 
output can be used by itself or along with the COMPRESSOR / LIMITER output for parallel compression applications, 
see 

‘Parallel Compression’ on page 18

 for additional information.

7.  Preamp Insert Connector 

Connect an external signal processor to this unbalanced connector to process the signal just after the preamp section 
and before the EQ.

8.  Mic Input Connector 

Connect a microphone or stage D.I. box to this balanced XLR input connector.
