RANE

AC 23 / AC 23B

738

Active Crossovers

The Rane AC 23 and AC 23B

active crossovers offer the

identical features and specs as

the AC 22 and AC 22B but with the ability to be configured for stereo 2- or 3-way, or mono 4- or 5-way operation. The AC 23,

like the AC 22 is available with1/4” TRS balanced/unbalanced inputs and1/4” TS unbalanced outputs while the AC 23B is

provided with XLR connectors

with active balanced inputs

and outputs.

SAC 22 / SAC 23

Stereo 2-Way and Stereo 3-Way Crossovers

The SAC 22 and SAC 23 employ the

same state-variable 4th-order

Linkwitz-Riley filters with steep 24dB

per octave rolloff slopes, as the AC 22

and AC 23 ensuring identical phase

characteristics on its low pass and high

pass outputs. The SAC 22 utilizes a single 31-position precision DC control voltage potentiometer to simultaneously select

the low and high frequency points while the SAC 23 uses two 31-position controls divided between low/mid and mid/high

crossover regions. This crossover circuit design provides a smart and easy way to biamp or triamp your audio system

while at the same time ensuring consistent accuracy from channel-to-channel and unit-to-unit that provides a distinct

advantage over continuously variable

designs using ganged potentiometers

which can yield large variations in

channel-to-channel matching. Both

units also feature active balanced XLR

inputs and outputs.

Crossover Features

◆ 31-position detented stereo crossover controls provide the simplest

way to biamp (SAC 22) or triamp (SAC 23) your system

◆ Same 4th order Linkwitz-Riley crossover design as the AC22/23

◆ An input level control allows decreasing the overall sensitivity of the

entire sound system, including the mono subwoofer if one is used

◆ Separate low, high and mono subwoofer output level controls allow

compensation for sensitivity variations in amplifiers and drivers

Inputs and Outputs

◆ Separate balanced XLR connectors are provided for the left and right

inputs as well as the stereo low and high outputs. Additional left and

right XLRs are provided for the mid outputs of the SAC 23

Subwoofer Output

◆ The mono subwoofer out, with switchable 100Hz LP Filter, provides a

separate mono sum of the left and right low outputs.

◆ The subwoofer output may be used along with the left and right low

outputs
