AC Power Hookup

The Dual Tube EQ has an internal power supply designed to

operate at 100 to 125VAC, 50 to 60Hz. Units manufactured for

use outside of the United States of America have been modified

to comply with the required electrical specifications. Under no

circumstances should the power cable be altered. If the cable

becomes cut or damaged, discontinue its use and have it

replaced before using the Dual Tube EQ.

Audio Connections

Audio connections to and from the Dual Tube EQ are balanced

XLR (Pin 2 Hot (+), Pin 3 Cold (-), Pin 1 Ground) and unbal-

anced 1/4” (Tip Hot (+), Sleeve Ground). We recommend using

only high-quality cables equipped with the appropriate connec-

tors.

Installation

The Dual Tube EQ may be employed in a number of setups

including:

- Between a mic/ line preamplifier and a mixer, digital multi-track

recorder, DAT machine, hard disk recorder, or analog recorder.

- In a mixer’s channel insert points.

- Between a mic/ line preamplifier and signal processors.

- Between electronic musical instruments (synthesizers, guitars,

bass, samplers, acoustic instruments with pickups) and other

gear.

* Note: The Dual Tube EQ is NOT a mic preamp! It doesn’t

have enough gain to amplify the mic signal to line level!

SAFETY PRECAUTIONS

Warning: To avoid the risk of shock or fire, do not expose this

unit to moisture. Do not remove metal panels from the main

chassis. Disassembling the chassis exposes dangerous volt-

ages. There are no user-serviceable parts inside. Refer all ser-

vicing to qualified personnel. Note: If your power cord becomes

damaged and must be replaced, always replace it with the

proper type (3 prong).

POWERING UP

It is important to remember to turn the Dual Tube EQ on before

any monitoring levels or power amps are turned on. The Dual

Tube EQ has the ability to add gain to its input signal. This can

cause the Dual Tube EQ to produce a “thump” on power up and
