Rane SAC 23 Crossover stereo 3 way, 31 frequency selector £339.99
Description
The SAC 23 employs state-variable 4th-order Linkwitz-Riley filter alignments to minimize phase difficulties in the critical crossover region. Simply put, a Linkwitz-Riley crossover exhibits identical phase characteristics on its Low pass and High pass Outputs. This characteristic guarantees in-phase outputs at all frequencies. In-phase outputs are mandatory for proper acoustic summing of common signals from adjacent drivers in the crossover region. An added benefit of this topology is steep 24 dB per octave rolloff slopes. A slope of this magnitude guarantees drivers designed to produce a specific range of frequencies, and no more, will not be driven past their limits, thereby minimizing distortion and driver fatigue.
The SAC 23 utilizes 31-position precision DC control voltage potentiometers to select the Low/Mid and Mid/High Frequency points. This crossover circuit design assures consistent accuracy from channel-to-channel and unit-to-unit. This is a distinct advantage over continuously variable designs using ganged potentiometers which can yield large variations in channel-to-channel matching.
The Mono Sub Output provides a separate mono sum of the Left and Right Low Outputs. A 100 Hz low pass filter may be activated for this Output. The Sub Output may be used along with the Left and Right Low Outputs.
The Input Level allows decreasing the overall sensitivity of the entire sound system, including the mono subwoofer if one is used. The Low Level, Mid Level, High Level and Mono Sub Output Level controls allow compensation for sensitivity variations in amplifiers and drivers.
The SAC 23 features balanced XLR connectors that when properly connected, can drive long lines without fear of dreaded hum.
