Bridge Mode Operation (PA1000X/PA1800X)
The PA1000X and PA1800X can be operated in mono bridged output mode, if your speakers can handle the following power output levels:
PA1000X: 320 watts
PA1800X: 420 watts
As shown in the diagram below, connect the speaker's positive (+) to the amplifier's red speakers left (A/B) terminals and negative
The speaker righr (+) on the amplifier is used a negative
NOTE: IT IS SUGGESTED TO USE A
STEREO/MONO SWITCH IN
"MONO" POSITION
BRIDGED SPEAKER HOOKUP
Using headphones
To listen privately, or to monitor sound sources, connect a pair of low impedance stereo headphones (not supplied) with 6.35mm plug into the PHONES jack on the amplifier front panel.
Please listen safely. Follow these recommendations: Do not listen at extremely high volume levels. Extended,
Always start with the volume control set to a LOW level BEFORE you put the headphones on. Then gradually increase the volume as necessary.
Connecting to standard AC power
After making all other connections, set the POWER switch to OFF position. Then connect the power cord to a standard AC outlet.
Mounting the amplifier
This amplifier is designed to accept standard rack mounting installations. Two slots on each end of the front panel make it suitable for such an installation.
Tightly secure four mounting screws (not supplied) through these four slots and into your standard electronics equipment rack.
Turning the amplifier on
1.Turn on the audio input source equipment which is connected to the amplifier INPUT jack.
2.Set the amplifier's left and right output level gain controls to the minimum level settings.
3.Press the power switch to turn the amplifier on.
Using the power meter (PA800X/PA1000X/PA1800X)
The meter POINTER (PA800X/PA1000X) and/or LED (PA1800X) position indicate the amplifier output power. For ease of reading in dark environments, the VU meter (PA800X/PA1000X) is illuminated.
Using the meter range selector (PA800X/PA1000X)
When output power is too strong, the meter's pointer might continuously swing to the extreme right and damage or reduce the accuracy of the meter. To protect the meter, you can use the meter range selector to control the amplifier's sensitivity to the input power signal.
Leave the meter range switch in the OUT position to maintain a 0 dB gain for the mater. When output power is not strong, leave the meter range switch in the IN position to allow a +20dB gain.
Using the left and right Output Level controls
Rotate output level gain clockwise to increase, or counterclockwise to decrease the output power. To get the best performance with the leaset sound distortion, always adjust the output level gain so the meter's level indication does not continuously exceed to the extreme right.
CAUTION: It is possible to overdrive the amplifier by setting output level gain too high, which may cause damage or failure.
About the internal clip circuitry
Special clip circuitry incorporated into your amplifier's design protects the amplifier and speaker system from being damaged from overdriving power.
Under normal conditions, the amplifier's clip indicator will flicker as the output power momentarily exceeds the level as set by the output level gain selector.
However, under excessive output conditions, the clip indicator lights remain on continuously, altering you that the special clip circuitry has become active. When this occurs, you should simply reduce the output power level by rotating the Master Volume control counterclockwise.
Using the A/B Speaker Selector Switch
You can listen to speakers on set A or set B individually or simultaneously. Simply push in or out the desired speaker set to make your selection.
