LA Audio EQ231-G
Dual 31-Band Graphic Equalizer

EQ231-G

LA Audio's EQ231G is a dual 31 band 1/3 Octave Graphic Equaliser in a robust 3RU high case.  The band pass filters are based around precision minimum phase active RC networks to deliver superior dynamic range and signal to noise performance. Long throw faders provide maximum sensitivity and control of 12dB cut and boost at 31 ISO centre frequencies from 20Hz to 20KHz.

The EQ231G incorporates a 24dB/octave, Butterworth type, High Pass Filter variable from 16 to 160Hz with bypass.  All switches have LED indicators.  The EQ231G has electronically balanced inputs and outputs on XLR.  An optional Transformer Output module is available, featuring Active Distortion Cancellation circuitry that reduces to negligible levels the LF distortion inherent in Passive Transformer designs.  Power relays ensure silent power on/off and also automatic bypassing of the unit when switched off.  The EQ231G is built in accordance with Electro-Magnetic Compatibility (EMC) and Low Voltage Directive (LVD) regulations encompassed within the European 'CE' mark.  This guarantees problem free integration into audio systems.
