PROSPEC 1U - Mono Input Channel Connectors (Rear Panel)
(ProSpec-1U8M includes 8 Mono Input Channels)
(ProSpec-1U4M4S includes 4 Mono Input Channels)
XLR portion Combo Microphone Input Connector
This connectors XLR portion is designed to accept typical microphone input signals, and has an input
impedance of >3000 ohms. This is a locking connector. To remove an XLR cable, depress the Tab on the
connector before attempting to remove the cable plug from the console connector.
1/4” TRS portion Combo Line Input Connector
The 1/4" TRS connector portion of this connector accepts line input signals and has an input impedance
of >10k ohms. The line input may be a balanced or unbalanced signal.
1/4” TRS Insert Connector
This connector allows external processing or effects electronics to be inserted into the channel’s signal
path after the fixed high pass filter. Tip= Send, Ring= Return, Sleeve= Ground. Examples of external
devices include additional equalization, notch filters, compressors, limiters, vocal doublers and
harmonizers, reverb devices, etc. The insert send has an output impedance of 100 ohms unbalanced and
the insert return has an input impedance of 5k ohms unbalanced. Operating level is +4dBu.
NOTE: The user should ensure that any device inserted into the channel’s signal path 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 Insert Connector used as a Direct Output
In place of its insert function, this connector may instead be used as an unbalanced direct output. The
connector provides a unbalanced line level output of the input channel’s signal by using a 1/4" male
connector where the Tip and Ring have been tied (shorted) together. This utility output can be used to
feed a multi-track recording device, effects device, or to feed another mixing or processing device
including distributed monitor mixing systems.
