INTRODUCTION

The ROLLS REQ315 graphic equalizer is intended for room equalizing or sound

shaping and the approximate frequency response curve can be seen graphically

by the settings of the frequency controls.Recording and broadcasting studios,

sound contractors and musicians will appreciate the low noise, straightforward

design, and versatile signal control of the REQ series.The REQ315 frequency

filters are “constant Q”meaning the width or shape of the filter curve does not

change as the frequency level is increased or decreased.This provides much

more accurate frequency adjustment.

INSPECTION

1.Unpack and inspect the REQ315 box and package.

If obvious physical damage is noticed, contact the carrier immediately to make a

damage claim.We suggest saving the shipping carton and packing materials for

safely transporting the unit in the future.

2.Please register online at www.rolls.com, or complete the Warranty Registration

Card and return it to the factory.

Front Panel Controls

1.Power Switch:

To turn the equalizer ON or OFF , press the upper or lower portion of this

button.

CAUTION: Always turn on your equalizer BEFORE your power amplifiers are

turned on , and always turn off your equalizer AFTER your power amplifiers

have been turned off.

2.Filter‘Level Controls:

Each of these sliders controls the output level of each of the 15 bandpass filters.

Center detent position is grounded for guaranteed flat response.

3.Filter Range Switch & Indicators:

The gain range of the filter sliders is switchable (as a group) from +/-6dB to +/-

12dB

For maximum boost/cut capability.At 6dB the green LED will illuminate and at

12dB the yellow LED will illuminate.

4.Bypass Switch & Indicator:

When the red LED is illuminated, this indicates that the unit or channel is in the

bypass mode.Signal is routed directly from the input to the output without

passing through any circuit (often referred to as “hard-wire bypass”).Use this

switch to compare equalized and unequalized material, or to bypass the EQ

section in the event of power loss or unit failure.

5.OverloadIndicator:

This red LED illuminates if any section of the equalizer is within 5dB of clipping.

Occasional blinking of this LED is acceptable, but if it remains on more than

intermittently you should turn down either the equalizer’s level controls or

reduce the output level of the preceding compon ent to avoid andible distortion.

6.Low-Cut Frequency Control:

To cut down unwanted signal, this control determines the roll-off frequencyof the

High-Pass Filter (HPF) in the instrument.The roll-off frequency cans de ad-

justed from 10Hz to 250Hz by turning this knob.Because of its high roll-off

slope, the HPF can be efficiently used to cut down the “HUM”noise from

preceding instruments, or to prevent the low-frequency resonance while the

speakers are installed in an enclosed acoustic environment.

7.Level Control:

This controls the level of signal coming into the instrument.Turn this control

down if the OVERLOAD LED illuminates steadily (meaning too strong on input

signal). Unity gain can be set by turning this knob to its center detent position.

EXAMPLE

8. Power Cord:

This cord is used to connect the AC power source to your equalizer.

CAUTION: DO NOT REMOVE THE CENTER GROUNDING PIN.

9. Fuse Holder:

This fuse holder contains an AC primary fuse.This fuse should be replaced

by the same type fuse when this is blown out.If they continuously blow, stop

replacing fuse and refer servicing to qualified personnel.

10. Input/OutputConnectors:

1/4 ”TRS

TheTRS (Tip Rinb Sleeve) connector is balanced and wired as tip=Lo (-) ,

Ring=Hi (+) , and the Sleeve = Ground.

CAUTION:Only one of these sockets can be chosen for audio connection at the

same time.

XLR

The XLR input connector is balanced and wired as Pin2=Lo (-) , Pin3=Hi (+) ,

Pin1=Ground

CAUTION: Only one of these sockets can be chosen for audio connection at

the same time.

Shown below is an example connection diagram for the REQ315.The main right

and left outputs of the mixer are connected to Channel 1 and 2 Inputs via high

impedance 1/4” unbalanced plugs.The equalizer is then connected to an ampli-

fier.

Note:This is only an example.For improved performance, use balanced XLR

connectors.
