CAUTION

RISK OF ELECTRIC SHOCK! DO NOT OPEN!

Terminals marked with this symbol carry electrical current of sufficient magnitude to constitute risk of electric shock. Use only high-quality professional speaker cables with ¼” TS or twist locking plugs pre-installed. All other installation or modification should be performed only by qualified personnel.

This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure – voltage that may be sufficient to constitute a risk of shock.

This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Please read the manual.

Caution

To reduce the risk of electric shock, do not remove the top cover (or the rear section). No user serviceable parts inside. Refer servicing to qualified personnel.

Step 3: Getting started

Connection Instruction

Make sure the amplifier and your sound source are turned OFF.
Turn on your sound source (mixer, CD player, computer).
Set the output levels on your sound source.
Adjust the GAIN CONTROLS to set the input levels.
If the LIMIT LEDs light up continuously, lower the GAIN CONTROLS until the LIMIT LEDs only light occasionally. This level should give you the best balance between signal strength and amp headroom.

Connection

Step 4: Bi-amping

Bi-amping splits a mono signal into upper and lower frequency bands, and then assigns each frequency band to separate speaker cabinets. A subwoofer typically takes the low frequency range. By splitting the signal this way, the speakers work more efficiently, and you can achieve a cleaner overall sound.
