CONNECTIONS GUIDE
The TRP3’s rear panel supplies one Neutrik 3-pin XLR input per
channel. Microphone input connections are made via female XLR
connectors with Pin-2 + or high, Pin-3 – or low, and Pin-1 ground.
The XLR Input routes through the preamp gain stage, high-pass
filter EQ, and Output Level control to the XLR output.
The output of the TRP3 emulates a transformer-coupled output and
can be used as either a balanced or unbalanced signal (depending
on how your cable/system is configured). When balanced, the
maximum output level is +27 dBu; when unbalanced, the maximum
level is +21 dBu. (These are as measured into a 600
Ω
load; the
recommended load is > 10
k
Ω
; 0 dBu = 0.7746 V rms.)
When unbalancing the XLR Output, pin-3 must be tied to ground
at the receiving end (i.e. the input of the following device). Do not
tie pin-3 to ground directly at the output of the TRP3.

To maintain the best performance from your new AEA TRP3
preamp, take note of these two requirements:
Never place preamp in close proximity to electromagnetic
fields or hot surfaces. Electromagnetic fields created by power
transformers, motors, or RF transmitters can potentially damage or
interfere with the preamp functionality. Make sure to keep your
preamp away from these sources in addition to hot surfaces.
Before turning on the power, all connections to the preamp
should be made and the Gain and Output Level controls set at
their minimum settings. Be sure to examine your signal chain
before powering up the preamp to ensure sudden loud noises are
not emitted which could damage your system or hearing.
