Rolls RPQ160 Parametric Equalizer
Rolls RPQ160 Parametric EQ.
The RPQ160 is a four-band parametric equalizer for the professional audio installation and music market. The unit is housed in a steel painted 1U rack space chassis, has an internal power supply, and is designed to withstand the rigors of road use.
Each frequency band has a variable Frequency select control which adjusts the frequency center, a Width (Q) control which varies the shape of the equalization curve, and a +/- 15 dB Level control. Additional frequency control has been provided with variable High and Low pass shelving filters. An overall Level control, a Bypass switch, and a Power LED round out the front panel.
Since equalization is used on virtually every type of audio signal and in many various applica- tions, the RPQ160 has RCA, 1/4″ and XLR inputs and outputs provided on the rear panel.
