The NAD CI 9060 is a clean-sheet design 6
channel amplifier specifically engineered to meet
the demanding requirements of the advanced
custom installation market. The result of this
intensive design effort is an amplifier that sets
new standards for "bullet-proof" reliability and
sonic performance in this specialized category.
Power
Many of the amplifiers designed for multi-zone
distributed audio are just not powerful enough.
The CI 9060 at 80 Watts Continuous power per
channel, boasts nearly double the power of most
other competing amplifiers. This is very critical,
because unlike a normal hi-fi amplifier that only
has to send its signal to speakers across room,
custom installations often demand that the signal
be sent from one end of the home to the other.
The series resistance of long runs of speaker
wire combined with impedance-matched volume
controls can create special demands on an
amplifier that the CI 9060 has been designed to
overcome.
OMC
NAD's proprietary Output Management
Circuit (OMC) ensures that the full power is
available at any reasonable load impedance.
If the load impedance falls below 3 ohms,
indicating something other than a loudspeaker
is connected to the amplifier channel, the
OMC will limit the power flow and prevent
the amplifier from overdriving or overheating. This is
not only protects the amplifier, but it also prevents loads
attached to the amplifier from heating up excessively, an
important factor when the liability of an installed system
is a consideration. When the OMC detects a potential
fault situation and begins to limit current flow, an amber
coloured LED illuminates on the front panel to alert the
installer to a problem in the system. When the OMC
is activated, the amplifier will continue to play without
distortion, but the power level will be reduced to the
amplifier channel that has the problem.
Reliability
Every design decision, both the electronic and mechanical,
was made with absolute reliability as the primary goal.
An auto-resetting protection circuit is also part of the CI
9060's design. The fast acting protection circuit jumps into
action if the amplifier overheats or encounters a dead short
circuit condition. A red front panel LED indicates that the
protection circuit has been activated. When the condition is
normalized the amplifier resets to Standby condition. In the
unlikely event of amplifier failure, the CI 9060 is designed
to be easily field serviceable with all amplifying circuitry
mounted on plug-in modules.
Low pressure cooling
With the CI 9060's highly efficient low-pressure cooling
system, it is very unlikely that the protection system will
ever encounter an overheating situation. High-volume,
low-pressure, fans keep both the power supply and the
output stage cool, yet are essentially quiet in operation.
Thermostatically controlled, the fans automatically adjust to
the ambient temperature to insure the optimum operating
conditions for the amplifier at all times.
Flexibility
The ideal Custom Installation amplifier not only has to have
absolute reliability and great sound quality, but it also must
be flexible enough to interface correctly with a variety of
other devices, and often diverse system requirements.
NAD has developed two unique features that endow the
CI 9060 with exceptional flexibility.

- Page 2 Flex-Pad This is managed by the Automated Turn-On Logic (ATO Logic) The Flex-Pad allows the CI 9060 to drive from 1 to 6 independent circuit that requires the amplifier to be switched back to standby zones, in any configuration of stereo or mono (or in mixed in the same manner by which it was activated. In other words, if combination), without resorting to the confusion, sonic it is switched on via a 12V control signal, it cannot be switched to degradation, and questionable reliability of switches. Instead, the standby via the front-panel switch, it must wait for the 12V signal. Flex-Pad uses the tried and true patch-bay concept to configure the amplifier channels. The configuration is visually obvious, making Summary it easier for technicians to set up the system and to troubleshoot High power, bullet-proof reliability, absolute protection and safety, for system errors.
