SPECIAL INSTRUCTIONS

POWERPAC 120/300

The PowerPac 120/300 remote on/off function allows the user to link the power on/off of an amplifier, or group of amplifi- ers, to an external preamp, or other control product. This is useful in installations, such as home theater, which usually present a convenience problem for powering up mul- tiple amplifiers, often at distant locations from the source.

Located on the front panel of the PowerPac 120/300 (see illustration), is a two terminal 12 volts (active range 9 -12

volts AC or DC of either polarity), input connector and a potentiometer. The PowerPac amplifiers can then be powered- up by an external 12-volt signal connected to the terminals of the jack.

This jack will accept 1/4 -inch stripped wire ends, inserted into the square holes provided, and the adjacent screws care- fully tightened to hold them in place. The internal "delay" turn-on circuit, will delay turn–on between 1 and 10 seconds, follow- ing application of the 12-Volts. In this way groups of amplifiers may be sequenced on to distribute power surges over a period of time.

The power switch must be left in the “off” position, at all times for the PP120 amplifier to operate in the re- mote mode.

The PP300 has a 3-position switch al- lowing for ‘Local (on)’ or ‘Off ‘or ‘REM (remote)’ power selection.

The amplifier will remain powered-up while the 12-Volt signal is present, and will turn off when the 12-Volt signal is switched off.

Input sensitivity is selectable using the ‘INPUT’ slide switch. In the ‘ BAL REG' posi- tion, 2 Volts in will give 100 Watts into 8 ohms at the output. This is the recom- mended setting when using Bryston pre- amplifiers or other pre-amplifiers having ac- tive balanced outputs. This setting also pro- duces the lowest noise floor.

The ‘BAL +6 dB ” setting adds 6 dB of gain to provide an input sensitivity of 1 Volt in = 100 Watts / 8 ohms at the output for outputs that are transformer coupled, or low level sources.

The ‘UNBAL ’ setting selects the gold plated ‘phono’ type connector. The input impedance is 50K ohms.
