CONNECTING YOUR PREAMPLIFIER
Setting up your preamplifier is rather easy.
1. Please refer to page 8 diagram 3 for an illustration of the back of the preamplifier.
2. There are two pairs of UNBALANCED RCA main outputs electically identical.
Connect either (or both for bi-amping) of the RCA outputs to the input of your amplifier 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
functionally and electronically the same only the labels are different.
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.
