A further parameter “

Min

” may also be available for more advanced applications. This allows the 

increasing limiting action at lower frequencies to level-off below a certain frequency. In most 

application, this would be left set to its default value of 5Hz.

 

Amplifier Gain 

Expressed in dB, this is the gain of the amplifier which the output of the SC48 is feeding. This value 

must be entered to allow the SC48 to correctly calibrate the thermal and excursion limiter for the 

amplifier in use. 

Routing 

Outputs can be driven from any DSP input. This routing is the fundamental means by which Drive 

Modules are created. Routing should always consume outputs consecutively alphabetically and 

numerically. However, non-consecutive Drive Modules may be created using manual routing and 

Recalling Components

. See the 

drive module

 section of this user manual for more information. 

AES3 

AES3 outputs are switched in pairs from System Engineer or front panel. The limiter calibration for 
AES3 outputs is 0dBFS = +20dBu. 
 

Utility Pages 

Screen Contrast 

The Screen page in the “

UTILITY

” section

 adjusts the contrast (and optimal viewing angle) of the 

screen from 0-

100% in 1% increments using encoder “

A

”.

 

Stereo Linking 

Stereo linking is available between DSP Drive Modules A & B and between C & D. Changing a 

parameter in either of the stereo linked Drive Modules will change the other linked Drive Module. 

Stereo linking is controlled by the 

STEREO

 

page in the “

UTILITY

” menu.

 

Note: Stereo linking will only work when the linked Drive Modules are of equal size. 

Current Ethernet IP Address 

This may be viewed in t

he “

IP Curr

” page of the “

UTILITY

” menu

. This value cannot be edited. 

 

IP Mode 

The Ethernet IP address may be automatic “

Auto

” or may be a fixed static value “

Static

” as 

determined by the “IP Mode” page of the “

UTILITY

” menu.

  

WARNING 

 Do NOT use Static mode unless your IT system specifically requires it. Auto mode 

should always be used where possible since in this mode, the SC48 

can always be ‘discovered’ by 

the System Engineer application. When in Static mode, the IP Address will flash on the Home 

screen.

 

Also see 

Ethernet Configurations

. 

IP Static 

This allows the Static Ethernet IP address to be adjusted by the three rotary encoders on the IP Static 

page of the 

UTILITY

” menu.

 This will only have effect when in Static mode.
