MONO INPUT MODULE REAR PANEL CONNECTORS
1/4” TRS Direct Output Connector
The connector provides a 100
Ω
, impedance balanced line level output of the input channel signal. The
front panel Direct Output switch selects the signal between a Post-fader source and a Pre-fader source. The
default signal for the Pre-fader position is AFTER the (1) microphone pre-amplifier but before all other
processing. Additional sources for this output include (2) post high pass filter/insert point, and (3) post EQ.
This utility output can be used to feed a multi-track recording device, effect device, or to feed another
mixing or processing device including distributed monitor mixing systems.
Any changes to the pre fader direct output source options should be made by a qualified technician.
1/4” TRS Insert Connector
This connector allows external processing or effects electronics to be inserted into the channel signal path
after the variable high pass filter. Examples of external devices includes additional equalization, notch filters,
compressors, limiters, vocal doublers, reverb devices, etc. The insert sent has an output impedance of 100
ohms unbalanced and the insert return has an input impedance of 10k ohms unbalanced.
Spectra-T includes an INSERT ON switch with LED to activate the return on this connector (the Insert send
signal is always active) in the Spectra-T mono channels signal path. The insert connector is always active on
Spectra-C consoles. NOTE: The user should ensure that any device inserted into the channel is capable of
maintaining the signal integrity of the console. The device must be able to accept a +22dBu signal without
clipping, and have an output impedance of 100
Ω
or less and be capable of d22dBu into a 2k
Ω
load.
1/4” TRS Line Input Connector
This connector accepts line input signals and has an input impedance of >10k ohms. When the front panel
source switch is selected to line input, signal is first sourced from this connector. If nothing is plugged into
this connector, the XLR input is normalled through this connector as a line input signal. The line input may
be balanced or unbalanced signal.
XLR Input Connector
This connector accepts microphone or line input signals, as determined by the front panel input source
switch and if the 1/4” TRS line input connector is occupied. When the front panel input source switch is in
the microphone position, this XLR connector will be used as a microphone input and will have an input
impedance of >3K
Ω
. When the input selector source switch is in the LINE input position and nothing is
plugged into the 1/4” line input connector, this XLR connector is used as a balanced line input with an input
impedance of >10k
Ω
. If a connector is plugged into the 1/4” line input connector, the XLR connector will
always be configured as a microphone input connector with an input impedance of >3 k
Ω
. This is a locking
connector. To remove an XLR cable, depress the Tab on the console connector before attempting to remove
the cable plug from the console connector.
