Manley PURIST PREAMPLIFIER - Manual (Page 5)

CONNECTING YOUR PREAMPLIFIER
Setting up your preamplifier is rather easy.
1. Please refer to page 7 diagram 2 for an illustration of the back of the preamplifier.
2. There are three sets of main outputs, two identical sets of UNBALANCED RCA
and the other BALANCED XLR. The BALANCED XLR's can be used with unbalanced
inputs and either "leg" can be shorted to ground with no ill effects. This output is 6 dB
louder than the unbalanced outputs because both "legs" contribute to the measured
output. The pin out for the XLR is as follows:
PIN1 - ground
PIN2 - POSITIVE going phase (+)
PIN3 - NEGATIVE going phase (-).
Connect either (or both for bi-amping) the XLR or RCA output to the input of your ampli-
fier as required.
3. UNBALANCED inputs are found on RCA jack inputs and can be connected to any line
level sources such as CD players, tuners or tape decks.
4. All RCA jacks are clearly labelled as to a typical function. Each input is for all intents
other than the labels functionally and electronically the same.
5. The record output is not buffered and it is recommended that one have the tape feed
plugged into the REC OUT only when actually recording. Care should be used when
using a 3-head tape/monitor switch as this record out is not a tape loop.
6. On the left end of the back panel is a standard IEC mains connector. This should be
connected to a standard mains outlet with the supplied cable. This unit has been hard-
wired for the mains voltage in your country
7. Power up the preamplifier FIRST and allow it to settle for a minimum of 30 seconds
before powering up your amplifiers. Turn off your preamplifier and source components
LAST when powering down a system. This prevents amplification of turn-on transients
and other noises when powering up or turning a system off and ultimately protects the
speakers.
