QUICK GUIDE TO THE MICROPHONE PREAMPLIFIER MODULE
Each Legacy Preamplifier module can contain two separate PCAs with five mic preamps on each
assembly. The console comes standard with one Preamp module with one five-input mic preamp PCA
that allows an additional five-input preamp PCA to be retrofitted. A second Mic Preamp (with either
five or ten inputs) can be added to the console.
Each Mic Preamp PCA has five 3-pin analog microphone input connectors and five 6-pin analog
audio output connectors. Each input connects to a separate mic preamp driving its own line-level
balanced analog output connector. The connectors are hidden by the meter panel in normal operation
and the trimpots, visible to the operator, are covered by a security cover.
INPUTS
1 - 10 — The 3-pin analog inputs accept mono microphone signals.
Connect only low impedance, balanced, dynamic or condenser
microphones, with nominal mic output levels of -65 to -30 dBu, to these
inputs.
OUTPUTS
1 - 10 — The 6-pin analog outputs are wired in parallel (mono) using
the standard pinout sequence. This allows these outputs to connect directly
to Universal Input modules without requiring any setting changes be made
to the Input Mode from a standard stereo input. The preamp output signal
level is +4 dBu.
