amp.1640 User Guide 1

Welcome to amp.1640

The Clare Controls amp.1640 is a 16-channel (8 zones) Class D amplifier. It is a

compact and efficient cool-running device housed in a 1U rack-mount chassis.

The amp.1640 uses an advanced switch-mode power supply to drive sixteen

channels, delivering 40 watts at 8Ω. The amp.1640 is stable to 4Ω.

The amp.1640 incorporates eight matched 2-channel amplifier modules that

deliver eight zones of clear audio performance. It uses two independent feedback

loops that provide lower distortion, less noise on output, a frequency response

that is less dependent on load and lower a output impedance than other Class D

amplifiers.

The amp.1640 also includes a switch-mode power supply that consumes less

than 0.2 W in standby. It implements a total of nine independent protection

circuits, monitoring the temperatures, currents and voltages of several different

functional blocks, assuring uninterrupted music until maximum limits are reached.

Features

Efficiency

The amp.1640 is built on Class D technology, running cooler, more efficiently

(greater than 90%), and more economically than traditional Class A/B amps, with

equal or better audio performance.

1 RU form factor

Class D amplifier technology can also be built into smaller, lighter components,

allowing us to fit sixteen high-performance channels in a space-saving 1 U rack-

mountable chassis.

Advanced protection

The amp.1640 features a comprehensive protection system with a total of nine

independent protection circuits. These circuits monitor the temperatures,

currents, and voltages of several different functional blocks to assure optimal

reliability.

Bridging

The power output of adjacent channels can be combined to provide additional

power when needed in certain areas. This is easily accomplished by setting a single

DIP switch and wiring accordingly.
