PANEL DESCRIPTION
■When Installing the Amplifier
DO NOT installing or mounting the amplifier in unstable locations, such as on the
rickety table or the slanted surface. It may result in the amplifier falling down
and causing body injury and/or property damage.
Be sure to ground to the safety ground (earth) terminal to avoid electric shock.
Never to ground to a gas pipe for tragic disaster may occur.
Use the amplifier only with the voltage specified on the amplifier. Using the voltage
higher than specified may cause fire or electric shock.
DO NOT cut, twist, damage, nor modify the power supply cord. In addition, avoid
using the power cord close to heaters, and don’t place heavy object, including
the amplifier itself, on the power cord, for it may cause fire or electric shock.
DO NOT expose the amplifier to rain or the environment where it may be splashed
by water or other liquids, for doing so, it may cause fire or electric shock.
WARNING

■When using the Amplifier
When found following irregular situation during amplifier is in use,
immediately switch off the power, disconnect the power supply plug from the AC outlet.
Don’t try to operate the amplifier again. Contact your local dealer to check the amplifier.
The amplifier falls.
Amplifier is malfunction.
Water or any metallic object gets into the amplifier.
The smoke or strange smell coming from the amplifier.
The power supply cord is damaged, such as exposure of the core,
disconnection etc..
DO NOT put cups, bowls, or other containers with liquid or metallic object in it on the
top of the amplifier. If they spill accidentally into the amplifier, it may result in
fire or electric shock.
DO NOT touch the power supply plug during thundering and lightning, for it may
result in electric shock.
DO NOT insert or drop the metallic objects or flammable materials into the
ventilation slots of the amplifier, for it may result in fire or electric shock.
DO NOT open nor remove the amplifier cover to prevent fire or electric shock, for
there are high voltage components inside the amplifier.
PANEL DESCRIPTION
■When Installing the Amplifier
DO NOT remove nor plug in the power supply plug with wet hands, for it may cause
electric shock.
When unplug the power supply cord, be sure to grasp the power supply plug. DO
NOT pull on the cord itself. Operating the amplifier with damaged power
supply cord may cause fire or electric shock.
Avoid installing the amplifier in humid or dusty places, the area exposed to the
direct sunlight, locations generating smoke or steam, or the spot near the
heaters. It may result in fire or electric shock.
When moving the amplifier, be sure to remove its power supply cord from the wall
outlet. Moving the amplifier with the power cord connected to the outlet may
cause damage to the power cord, and resulting in fire or electric shock. When
removing the power cord, be sure to grasp its plug to pull.
DO NOT Block the ventilation slots of the amplifier chassis. It will cause the
temperature rising and result in fire.
CAUTION

■When Using the Amplifier
Make sure that the volume control is turned to minimum position before power is
switched on. Loud sound produced at high volume when power is switched on
may impair hearing.
DO NOT place heavy objects on the amplifier for it may cause it fall and may result
in body injury and/or property damage. Besides, the object itself may cause
damaged or body injury.
DO NOT operate the amplifier for the extended period of time with the sound
distorting. It is an indication of malfunction, which can cause heat and result in
fire.
Switch the power off, and unplug the power supply plug from the AC outlet for safety
purposes, when cleaning or leaving the amplifier unused for 7 days or more.
Fire or electric shock may occur.
If the dust accumulates on the power supply plug or in the wall AC outlet, fire may
result in. Clean it periodically. In addition, make sure the plug is inserted in
the wall outlet securely.
Contact your local dealer to clean the dust, it the dust has accumulated in the
amplifier for a long period of time. Dust accumulation may result in fire or
damage.

3. Connection
Example:
1. Driving a single 8 ohm speaker with the combined 4 ohm power of both channel
2. Driving a single 4 ohm speaker with the combined 2 ohm power of both channel
Precautions:
1. Bridge mono mode makers it possible to drive thousands of watts into a single speaker AC
current consumption will usually be higher avoid excessive single level and made sure the
wiring speaker can handle the power.
2. Do not use 2-ohm loads.
Installation:
Rack mounting of the amplifier is optional use four screws and washers when mounting the
amplifier to the front rack rails.
Connections inputs:
Each channel has active balanced XLR and 1/4” (6.3mm) inputs wired in parallel. The input
impedance is 20k ohms balanced 10k ohms unbalanced.

Balanced signals are less prone to AC hum, but unbalanced signals can be suitable for short
cable runs. The signal source’s output impedance should be less than 600 ohms to avoid
high frequency loss in long cables.
Balanced inputs: Use the XLR or 1/4 (6.3mm) TRS input jacks, or the barrier strip.
Unbalanced inputs: Connect the unused side of the balanced input to ground, as shown
aboveleft. Atip-sleeve 1/4-inch (6.3mm) connector will correctly terminate the unused side of
the input without modification.
For two-channel (stereo) operation, use the inputs for both Channel 1 and Channel 2; for
parallel or bridged mono operation, use the Channel 1 input. To patch the audio signal to
other amps(parallel and bridged modes only).
SPEAKER CONNECTIONS
Connect the left-side loudspeaker to the left-channel speaker terminals and the right side
loudspeaker to the right-channel speaker terminals of this unit take care to observe connect
(+) and (-) polarity. If the polarity of one speaker is reversed, the speakers will be out of phase,
causing a loss in bass response and unstable, irregular stereo imaging.
Double-check to make sure that both speakers have the same polarity.
Itis recommended that you use high-quality, heavy gauge speaker cable with low resistance.
Designed specially for audio applications, using thin cable with high resistance may impair
sound quality and prevent the amplifier from delivering its full potential.
The speaker cables for both channels should be approximately equal in length, as a marked
difference can result in improper left/right balance.
Speaker Polarity note
Be sure to observe speaker polarity (+,- leads) throughout your system. Getting them wrong
can result in missing bass, massive distortion, or blown speakers!
Left positive (+) terminal to left speaker positive (+).
Left negative (-) terminal to left speaker negative (-).
Right positive (+) terminal to right speaker positive (+).
Right negative (-) terminal to right speaker negative (-).

Binding post outputs:
1. Strip back insulation not more than 13mm(1/2 inch)
2. Insert wire fully so that none of the conductor is exposed: tighten barrel (use coin if
necessary)
3. Non-European models only…
4. Spade lugs must have insulated barrels to prevent electric shock.
Speaker TM Output:
The PSAamplifier offers a choice of output connections, with two Neutrik NL4MD speakon
jacks and two pairs of “touch-proof” binding posts.
The speakon connector is designed specially for high-power speaker connections. It locks
in place, prevents shock hazard, and assures the correct polarity.
The upper speakon jack has both Channel 1 and Channel 2 output, so it is especially useful
for parallel, bi-amp, or bridged mono operation. The other speakon carries only Channel 2’s
output. See the illustrations as above.

For easier insertion, use the newer-style NL4FC speakon connectors with quick-lock thumb
latches.
WARNING: To prevent electric shock, do not operate the amplifier with any of the
conductor portion of the speaker wire exposed.
SPEAKER CABLING
Larger wire sizes and shorter length minimize both loss of power and degradation of damping
factor. Do not place speaker cables next to input wiring.
