UM TGMC-120117
Utility Cluster
Within the TG2 section, exists a cluster of utility push-button
switches labeled as follows:
DI, LINE, 48v, and PHASE
.
DI
Provision is made for accommodation of instrument level sig-
nals by means of a direct injection facility or
DI
.
Engaging the DI facility is achieved by setting the push-button
switch labeled
DI
to the inward position, this allows the Pre
Amp/EQ section to accept instrument level signal via the ¼”
input connector, which is located on the front panel.
When using the DI facility, the output signal will be available
from the Pre Amp/EQ section output XLR connector, which
is located on the rear of the unit.
Note:
Instrument level is not the same as line level signal.
Tip:
Enabling the DI facility decouples the Pre Amp/EQ sec-
tion’s input XLR, therefore creating a handy mute feature.
Line
The Pre Amp/EQ section is capable of accepting line level
signal.
To accommodate line level signal into the Pre Amp/EQ sec-
tion, first set the push-button switch labeled
Line
to the in-
ward position, then apply line level source to the
Pre Amp/EQ
input XLR connector, which is located on the rear of the unit.
Tip:
Sending line level source into the Pre Amp/EQ section
is a great way to further process material by adding the rich
harmonic texture available from this historic circuit; use a pair
of TG Microphone Cassettes on the mix bus!
48v
Provision is made for 48 volts phantom powering of con-
denser microphones, should they require it. Phantom power
may be enabled by setting the push-button switch labeled
48v
to the inward position, use only for microphones that require
it.
Warning:
Only engage or disengage phantom power while a
microphone is connected to the Pre Amp/EQ section of the
cassette. Disconnecting a microphone while phantom power
is on may cause damage to equipment downstream. Never
use phantom power with ribbon microphones. Do not en-
able phantom power when a line level device is connected at
the
Pre Amp/EQ
input XLR connector.
Phase
The push-button switch labeled
Phase
, when set to the in-
ward position, transposes the Pre Amp/EQ section input
XLR leads, therefore reversing polarity of the incoming signal
by 180º. This facility may be useful in multi-microphone sce-
narios, when a microphone is not ideally placed, a cable is
wired incorrectly, or source material is out of phase.
