Direct Out
Level – Gnd Lift
This level adjustment will allow you to match the D.O. signal you are sending, to
the proper level required by the mixer board or recording device. Most line level
devices are 4dB or -10dB. You can adjust for either, however, you can
also adjust your Direct Output signal low enough for microphone inputs with
below -30dB adjustment- this is an unusual capability. This allows you to use
your high quality balanced XLR Direct Output with low end mixer boards which
only provide mic level inputs. (A very handy capability when you walk into a
new venue cold and have no idea what the sound person might have to work
with.)
The D.O. in the TCA-500C is analog modeled to deliver to a flat response
system, a very closely EQ’d approximation to what is output from the combo
speaker in its cabinet.
The signal sent from the XLR connection is balanced line and male
gendered (standard XLR out). The GND Lift push button (rear panel)
allows the combo earth to be separated from the DI earth to assist with
hum ground loop issues. The front panel Direct Level control allows the
signal sent to the desk/house board to be easily adjusted over a wide
range.
Note: when the Power Amp On/Off switch (rear panel) is Off (i.e. no
sound is output from the combo speaker, but the headphones output is
still active), the D.O. output remains ON because the preamplifier
section is ON.
