woofer.
6. CROSSOVER – This knob is used to adjust the crossover frequency of the subwoofer.
7. LEFT SPEAKER GAIN CONTROL – This knob is used to regulate the output level of the left
speaker.
8. LEFT XLR PARALLEL OUTPUT JACK – This jack is used to send the incoming line level signal
from either of the Line Level Inputs Jacks to another subwoofer, speaker or other line level input
jack such as a mixer or power amp.
9. LEFT BALANCED XLR INPUT – This connection is designed to accept a balanced line input
signal from a mixer or other line level device with a balanced output jack. Use a balanced cable
when the signal cable length exceeds 15 feet, this will reduce excessive signal loss. Be sure to
connect only line level input devices such as mixers and tape machines to this jack.
10. LEFT SPEAKON CONNECTION – The speaker includes a pair of Speakon type connections.
You may use both connections at once to loop speakers. The Speakon connectors have a pin
1+ (hot) and 1- (ground) configuration, pins 2+ and 2- are not used. For more wiring information
regarding the Speakon connectors see page 12.
11. POWER LED - This L.E.D. will be lit when you switch on the power.
12. MAIN POWER INLET – This connector is used to supply main power to the unit via the in-
cluded detachable power cord. The power connection uses an I.E.C. type connector, use only
the supplied polarized AC power cord. Use only a power cord that matches this type of con
-
nection. Be sure to only connect this unit to a power outlet that matches the printed power
label on the unit. Never use a power when the ground prong has been removed or broken off.
The ground prong is used to reduce the risk of electrical shock in case of an electrical short.
This cord is designed to fit in one direction only. Do not attempt to force a cord if it does not
fit, be sure the cord is being inserted properly.
13. FUSE HOLDER – This housing stores the 10 amp GMA protective fuse. Always replace with
the exact same type fuse, unless otherwise instructed, by an authorized American Audio
®
service technician. Replacing with any other type of fuse than that of the recommended fuse
will void your unit warranty.
14. PROTECT INDICATOR - The red Protect LED will begin to glow when the channel goes into
protect mode. When the channel goes into protect mode all output for that channel will turn
off. This is to protect any speakers connected to the channel.
15. MAIN POWER SWITCH – This is the main power ON/OFF button. A yellow LED directly above
the power switch will glow indicating power is ON. Before main power is applied, be sure you
have made all connections to the speaker. Remember to avoid damaging pops to the speakers,
the mixer is turned on first and turned off last.
16. VOLTAGE SELECTOR SWITCH - Because power supplies vary from location to location a
voltage selector switch has been incorporated in the unit's design. This switch can select a
voltage input of 120v or 230v to accommodate the two major power source. Always be sure
to disconnect the power plug before changing the voltage.
17. CLIP L.E.D. - When your Subwoofer or Speaker Levels are distorted or too loud this L.E.D.
will light letting you know to adjust
your volume level to a lower setting.
