separate microphone signal output, the MIC LINE OUT (3).

This output carries the microphone signal amplified to line level. It can be used to feed the microphone signal to further external units such as a second NAD-911 or to link in with other separate sound installations.

USING SEVERAL NAD-911s.

The outputs of the main distribution preamplifier are connected to the first channels of the second unit to feed it with the music signal.

Use the main NAD-911’s MIC LINE OUT (3) to send the microphone insert signal to the second unit’s LINE INSERT IN (2) socket. This will ensure you maintain full control over which speaker channels get fed with the announcements and at what level.

NOTE: In the factory default setting, the Mic Line Out signal level is linked with the Microphone Level control (5) on the front panel. The NAD 911 configu- ration can be changed so that the Mic Line Out signal level is fixed, independent from the Microphone Level Control. Changing the configuration must be left to qualified personnel.

TAMPER-PROOF COVERS.

If the system is to be installed so that its level set- tings do not need to be changed in normal operation, then use the Tamper-proof Covers included with your NAD-911 to stop accidental use of the LEVEL con- trols and/or INSERT buttons. Fitting it with the Insert Button section of the cover to the right, will protect both the level settings and the insert button settings. Using the cover with the insert button section to the left leaves the insert button available.

Remove the volume control on any channels that need tamper-proofing, by gently pulling the LEVEL knob off its spindle.

GB

Gently push the Tamper-proof Cover in the opening left by the volume control knob. Ensure that the two small legs on the Tamper-proof cover line up with the two holes in the sub-facia behind the front panel.
