Power
The TG12345 Curve Bender is powered remotely by the
Chandler Limited
PSU-1
power supply, and connected at the,
four pin,
DC POWER
connector. The PSU-1 is an external
power supply capable of powering two units; the PSU-1 is
purchased separately.
Note:
Legacy PSU-1 power supplies featured external
grounding studs. As of mid 2015, grounding studs have been
removed and resistance applied internally.
Legacy PSU-1 Grounding Notes Only:
On the rear of the
legacy PSU-1 power supply are two black banana connec-
tors. These join the audio ground to earth ground with a sol-
id wire between them. Depending on your studio, you may
want this connected or disconnected. Turn up your monitors
or headphones a bit and experiment with which has a lower
noise floor in your system. You may also need to join the
audio banana plug to other sections of you studio to obtain
lowest noise floor. The audio banana is located closest to the
edge of the power supply case. Use something simple like a
guitar cord and touch the tip to other portions of your studio
to find best results. In some cases it may be best to connect
a 10 ohm resistor between banana plugs.
Audio Input & Output Connections
On the rear panel of the TG12345 Curve Bender exists, two
sets of male and female XLR connectors, one input/output
(I/O) pair for each channel side. All audio XLR connectors
are wired pin 2 hot.
