degradation, and questionable reliability of switches. Instead, the
Flex-Pad uses the tried and true patch-bay concept to configure the
amplifier channels. The configuration is visually obvious, making it easier
for technicians to set up the system and to troubleshoot for system errors.
The supplied patch cables can be easily reconfigured or replaced. This
can be especially important and can greatly simplify future service calls
years down the road (especially if system documentation is missing or
incomplete).
ATO Logic
The CI 9120 can be turned on in any one of three ways, for complete
system flexibility:
1. From the front panel switch.
2. Via the 12 volt trigger circuit.
3. By a switchable “sleep/wake” signal-sensing circuit.
This is managed by the Automated Turn-On Logic (ATO Logic) circuit that
requires the amplifier to be switched back to standby in the same manner
by which it was activated. In other words, if it is switched on via a 12V
control signal, it cannot be switched to standby via the front-panel switch,
it must wait for the 12V signal.
Summary
High power, bullet-proof reliability, absolute protection and safety,
combined with flexibility and NAD sound quality make the CI 9120
unique in the world of custom installation. Very small physical size and
the standard rack mount kit (3U) are just icing on the cake (The CI 9120’s
little brother, the 6 channel CI 9060 is the same physical size, making the
future expansion easy). Individual level trims for each channel help make
installation faster and easier. This is a new kind of amplifier that brings
NAD’s core values of performance, value, and simplicity to the custom
installation market place.
