4.4 Record Mute
At times when the NAC 552 record outputs are not required
it is good practice to mute them in order to minimise power
consumption and maximise sound quality.
To engage the NAC 552 record mute simply press the record
(lower) bank front panel
mute button.
4.5 NAC 552 Signal Outputs
To ensure correct continuity of system earth connections the
NAC 552 signal output is routed via the NAC 552PS power
supply. The NAC 552PS is fitted with multiple DIN signal output
sockets that enable the downstream connection of a stereo
power amplifier, a dual mono power amplifier or two separate
mono power amplifiers.
4.6 Auxiliary Power Output
The NAC 552 Input 7 socket is intended for use with a Naim
Audio StageLine or SuperLine phono stage and incorporates an
appropriate DC power supply.
