Rear Panel Cont.:
15. BALANCED XLR LINE 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.
16. TREBLE CONTROL – This knob is used to regulate the amount treble applied to the output sig-
nal. The maximum amount of treble gain is +12dB and the maximum amount of treble decrease
is -12dB. Turning the knob in a counter-clockwise direction will decrease the amount of treble
applied to a channel signal, turning the knob in a clockwise direction will increase the amount
of treble applied to a channel signal.
17. 1/4” LINE OUTPUT JACK – This jack is used to send the incoming line level signal from either
of the Line Level Inputs Jacks to another PXI 12P™ such as a mixer or power amp.
18. 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 PXI 12P™ or other line level input jack such as
a mixer or power amp.
19. BASS CONTROL – This knob is used to regulate the amount bass applied to the output signal.
The maximum amount of bass gain is +12dB and the maximum amount of bass decrease is
-12dB. Turning the knob in a counter-clockwise direction will decrease the amount of bass ap-
plied to a channel signal, turning the knob in a clockwise direction will increase the amount of
bass applied to a channel signal.
20. POWER LED - This L.E.D. will be lit when you switch on the power.
21. CLIP L.E.D. - When your Mic 1, Line Level 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.
22. GROUND LIFT - Turn this switch “ON” to help to reduce noise feedback and interference.
23. 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.
24. FUSE HOLDER – This housing stores the 3.15 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.
25. MAIN POWER SWITCH – This is the main power ON/OFF button. A green 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.
