Manual-1

QUICK START

Whoa, hold on there. Even if you don’t read manuals as a matter 

of principle, at least read this section to avoid hurting yourself or 

your equipment.

Connect the SAC 23 with the 

POWER 

off

. Balanced XLR 

cables are recommended, but if you must convert to ¼" connec-

tors, consult the RaneNote, “Sound System Interconnection,” in-

cluded with this booklet. 

This device uses low impedance balanced 

line drivers. Do not connect the “+” or “–” output pins to ground, as 

this may cause the power supply to shut down. For unbalanced use, 

leave the unused output pin (“+” or “–”) unterminated.

Consult the speaker manufacturers for the correct crossover 

FREQUENCY 

settings. As rugged as some drivers are, many 

(especially compression drivers) will not accept frequencies 

outside of their normal range without producing distortion and 

possibly self-destruction.

With all equipment turned off and 

LEVEL 

controls down, 

begin making connections to the system as shown on page 

Manual-6. When turning on the system, switch on the power

. Now, feed the SAC 23 some program mate-

rial. Start by turning up the 

LOW LEVEL, MID LEVEL

 and 

HIGH LEVEL

 to the 

0 dB

 marks. Slowly increase the 

INPUT 

LEVEL

, even if it goes all the way to 

10

, so the 

+4 dBu

 (green) 

light blinks occasionally and the 

OL

 (red) light stays out. This 

delivers the best signal-to-noise performance.

The 

MONO SUB OUTPUT

 is a sum of the Left and Right 

Low Outputs. The 

MONO SUB LEVEL

 adjusts only this 

Output and is not affected by the 

LOW LEVEL

 control. When 

using a single mono bass bin along with stereo mid- and high-

range cabinets, set the 

100 Hz FILTER

 to 

OUT

, allowing the 

front panel 

FREQUENCY 

to control the subwoofer crossover 

point. When used with 3-way cabinets and a subwoofer, set the 

100 Hz FILTER 

switch to 

IN 

to allow only frequencies below 

100 Hz at this output jack. This way, the SAC 23 almost does 

the job of a Stereo 4-Way crossover, but without removing that 

awesome bass from the Left and Right Low Outputs.
