The Q-Series
Furman offers fi ve different equalizers to best suit your needs: from a
single-rack-space mono 31 band, to a stereo 15 band with 60 mm long
throw sliders and VU metering in a two rack space.
The new Furman Q-Series EQ’s are designed for use by live sound
engineers, recording studios, and musicians. These units feature constant Q
circuitry with 4% center frequency accuracy. Each is equipped with 1⁄4” TRS
and XLR balanced inputs/outputs, and RCA unbalanced inputs/outputs for
the fl exibility to interface with a variety of systems.
Switchable to a +/-6 range for more control and better dynamics, they feature
+/-6 and +/-12 range LED indicators. Each channel bypass switch has a red
LED indicator to compare the equalized sound to the original sound, and
each channel is outfi tted with a clip LED for overload detection. A shielded
internal power supply provides for low noise operation. Selectable AC input
voltage between 120 VAC 50/60HZ and 240 VAC 50/60 HZ allows for use in
almost any location. Durable all steel construction makes these units perfect
for life on the road.
The Furman Q-Series is protected by a three-year limited warranty covering
defects in materials and workmanship.
