ART Pro Audio Dual Tube EQ - Two Channel, Tube EQ - Manual (Page 7)

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
