1. Inputs - For unbalanced inputs, the signal
should be on the + connection and the -
connection tied to ground. A mono 1/4” plug
used as an unbalanced connection will
automatically be grounded. When using a
stereo plug, XLR connector, or Euroblock for an
unbalanced signal, the (-) input connection
MUST be tied to ground.
2. Ashly Servo-Balanced Output - This output
circuit is an active output which maintains a
constant output level between the (+) and (-)
output terminals, regardless of either terminal
being connected to ground. This servo-
balanced output provides an unchanged signal
without regard to ground.
Installation
Use four screws and washers when rack mounting the Equalizer. For mobile use, the unit
should be further secured as appropriate.
General Requirements
GQX Equalizers have specific physical, electrical and signal requirements for proper
operation. These requirements will vary depending on your specific application, setup, and
the settings on the Equalizer. When setting up and testing your system, please take special
care to double check all connections and settings. Please refer to the specifications section
of this manual for specific input, output and other figures.
AC Power
Your GQX equalizer should be connected to a standard 3-wire grounded electrical outlet
supplying 100-240 Volts, 50-60 Hz. To reduce the risk of ground loop hum, connect all
audio equipment to the same electrical power source. Removal of the ground pin is both
unlawful and dangerous, as a potential shock hazard could result.
This unit will perform normally within the AC voltage range specified above. Voltages
less than this, as found in “brown-out” conditions, may reduce performance. In the event of
a blown fuse, replace only with same type fuse. No user serviceable parts are inside the
chassis. Overall power consumption is less than 25 watts.
NOTE : The power switch does NOT isolate the appliance from mains. Make sure the mains
power socket or an alternative disconnect device is near by and easily accessible. When the
product is connected to mains, the line-filter and the input of the fuse are energized.
