Section 2: Installation- Remote mounting (4-ch., Powerlight & non QSC amp’s)

REMOTE MOUNTING THE DSP-3 :4-Channel CX and DCA , Powerlight series, and all non-QSC amplifiers

Use of the DSP-3 with the 4-channel CX and DCA and all Powerlight amplifiers requires the remote mounting of the DSP-3. Use with non- QSC amplifiers also requires remote mounting. Keep in mind that all applications that use amplifiers that do not have a DataPort ( i.e. non- QSC amplifiers) some of the dynamic processing capabilities of the DSP-3 will not be available.

Accessory Remote Mounting Bracket- This accessory is a 19”, 2-RU panel with mounting facilities for up to four DSP-3 modules. It is intended to be mounted to the rear-support rails of an equipment rack. The bracket kit comes with one large bracket ( the 19”, 2-RU size) and four smaller right-angle brackets that are used for securely mounting up to four DSP-3’s in a 2-RU space. Adjustable rack ears are included for maximum mounting flexibility.

1- Attach the right-angle bracket to the DSP-3 module. The right-angle bracket is attached as shown, below.

2- Attach the DSP-3 & right-angle bracket to the main 19” bracket as shown, below.

3- Mount the main bracket assembly in your equipment rack between the rear support rails.

4- Attach the inputs, outputs, DataPorts, RS-232 and external power as required.
