Line Voltage

Units built for 110V-120V line voltage can be converted to 220V-240V by means of a modification. This is not simply a switch, and must be performed by a Sunfire Authorized Service Station. Contact Sunfire Technical Services for more information.

Muting System

The Sunfire Classic employs an electronic “clamper” to mute the main outputs to eliminate turn-on transients. (It will not interrupt the tape outputs).

Muting is accomplished by a shorting relay which, when it is “open”, is out of the circuit and hence has no effect on the signal. It is controlled by a toggling device, so muting cannot be partially “on”.

This muting system will turn off the signal to your power amplifier at these times:

•For about 40 seconds after the initial power-on, whether by the front panel power switch or the remote control.

•Immediately at turn-off, whether by the power switch or the remote control.

•The main outputs will also mute if the line voltage drops below 70 volts. This is to reduce thumping.

Output impedance

The output impedance of the Classic is a low 1.5K ohms, so it can drive power amplifiers having virtually any input impedance.

Options include connecting several power amplifiers to the Classic’s main outputs, to separately drive different speaker sets, or the use of extra-long connection cables to drive power amplifier(s) located close to the speak- ers, or self-powered loudspeakers. Conventional cables as long as 30 feet, or special low-capacitance cables as long as 60 feet, may be used to drive power amplifier(s) without difficulty.
