switch is depressed the LED will glow red and all eight-bands of
the Dual Tube EQ are active for the signal connected to chan-
nel One’s input and output jacks (labeled channel 1/MONO on
the rear panel). When this mode is used, the input and output
level controls for channel two do not affect channel one.
Another cool feature is that channel Two may be used as a
“tube” channel when the Dual Tube EQ is in Mono/cascade
mode. When in Mono/cascade mode, the input and output con-
trols and the tube are still available for use on Channel Two.
This is useful if you simply wish to use a channel of the Dual
Tube EQ to “sweeten up” a signal with a tube.
Power Switch
The Power switch applies and removes power from the unit.
The Dual Tube EQ should be turned “on” only when all monitor
levels are turned down, or off, to protect against any “thumping”
caused by high gain settings. Likewise, the Dual Tube EQ
should be turned “off” after turning all monitor levels down.
REAR PANEL CONNECTIONS
Input and Output Connections
The Dual Tube EQ’s XLR connectors follow the AES standard:
Pin 1 = Ground, Pin 2 = Hot (+), Pin 3 = Cold (-). The unbal-
anced 1/4” phone jacks are typical: Tip = Hot (+), Sleeve = Grd.
Input
One input jack per channel should be used at a time. Because
of its design, the Dual Tube EQ can be hard-wired without hav-
ing to disconnect the XLR inputs when using the 1/4” jacks. In
this case, if no load is placed on the XLR input (no instrument
or line-level source connected) the 1/4” jack will function as if
there was nothing connected to the XLR input. However, the
inverse is NOT true. If you are using the XLR input, you should
not have anything plugged into the 1/4” jack.
Output
Both balanced and unbalanced output connections may be
