Power Control Connections

Your amplifier features a built-in remote turn-on system that will automatically switch the amplifier on when another device in the system is switched on.

Remote Turn-On Using Products Equipped With a Low Voltage Trigger Jack

Press the front panel power switch on the amplifier so that it is in the ON position. Then, using an accessory cable with a 3.5mm mono mini-plug on each end, connect the trigger-output jack on the rear of the source device to the trigger input jack on the back panel of the amplifier. When these connections are made, the amplifier will automatically turn on whenever the triggering device is turned on.

Remote Turn-On

Using External AC to DC Power Converter

If your source device does not have a dedicated trigger jack, it is still possible to activate the unit for automatic turn on when a Switched Outlet is available on the rear of the source device. To control the amplifier in this fashion, you will need a small AC to DC power converter, capable of delivering a 3.3 to 24 volt DC signal. The DC voltage should terminate in a standard 3.5mm type mini plug. This type of converter may be obtained as a Power Adapter from many electronics retailers.

When installing, press the Main Power Switch on the front panel of the amplifier in so that it is in the ON position. Plug the AC adapter into a switched outlet on the source device that will be activated when you wish to have the amplifier turn on. This may be the switched outlet at the rear of an AC receiver or other audio equipment. Connect the 3.5mm mini- plug from the adapter to the trigger-input jack on the back panel of the amplifier. The amplifier will now turn on and off automatically, based on the status of the controlling device.

Power Connection

Once all audio and system connections have been made, connect the supplied power cord to the amplifier first, and then connect it to an AC power source. Please make certain that the amplifier is turned off and that the device connected to the remote trigger input is off when connecting the power cord and plugging it into an AC outlet.

CAUTION: Do not plug the amplifier directly into the “Switched Accessory” outlet of another device! These outlets are intended for use with low current draw products having a low current draw, such as tuners, CD players or cassette decks. These cannot handle the high current draw of a power amplifier. Using these outlets for a power amplifier is a significant safety hazard.

NOTE: It is not recommended that you connect other power amplifiers, or products with a high current draw, to the same AC power circuit as the amplifier. If this is unavoidable, the Ultra-Soft-Start circuitry of your amp will prevent excessively high inrush current.

Amplifier Operation

After all connections have been made you are ready for operation. First, turn on the source component in your system. It is always a good idea to turn on your amplifier LAST. This avoids the possibility of any turn on pops or transients from other equipment being amplified and sent to your speakers where they may cause damage. Always start with a low volume level on your controller or preamp to avoid damage to your speakers.

Manual On

Simply press the front panel Power switch to the “up” position. There will be a short pause from the time the power is turned on until power is applied to the speakers. This is intentional, and protects your speakers from damage while the amplifier stabilizes. To turn the unit off, press the Power button downward. The ON indicator light will go out and the STANDBY light will illuminate.

Automatic On

Make certain that the connection to the controlling device is correct. Whenever the controlling device is turned on, the amplifier will automatically turn on after a short pause. This pause is intentional, and it protects your speakers from damage while the amplifier stabilizes. You may also hear a relay click as during start up. This is also normal.

To turn off your amplifier, simply turn off the device feeding the amplifier it’s audio signals. The amplifier will automatically go into a standby mode in a few moments.

Gain Controls

Level adjustments may be made at the rear of the amplifier. The circuitry in your new amplifier may be different from your previous one, and by checking the output levels you will make certain that the control device, amplifier and speakers are properly matched. Be careful in adjusting these controls as they operate in conjunction with the volume control(s) on your source device. Be sure that the volume control(s) on the source device is turned down before adjusting the controls on the amplifier.

AC Line Connector and Power Cord

Your amplifier is supplied with an internationally approved (IEC) power line connector that accepts the supplied detachable, high-current capacity power cord.

WARNING: Under no circumstances should the round third prong on the plug be cut, bent or in any other way defeated as this may result in severe shock.

WARNING: Always turn off the amplifier and unplug the power cord before making any electrical connections.
