INPUTS - The PA-500 amplifier allows you to use two types of input connectors per channel, a XLR female jack for balanced connections and
a 1/4” TRS female jack that will accept balanced and unbalanced connectors. Use these connections to connect the output signal from a mixer,
cross-over or EQ to the PA-500 amplifier. A balanced connection is recommended for cable runs longer than 20ft. When constructing your own
XLR cables follow the pin configuration described below for proper connections. For cable runs shorter than 20ft., you may choose the 1/4TS
unbalanced input option. The 1/4” TS unbalanced input option may be more convenient for most users due to the abundant supply of
prefabricated cables available at your local audio dealer.
BINDING POST/BANANA PLUG: Connect your speakers to the binding post outputs on the rear of the amplifier. The speaker wire may be
connected by bare wire (directly connected, usually for permanent connections), banana plug, or spade connector. Connections are made to
channel one and channel two outputs for Stereo Mode or across the red terminals of channel one and channel two for Mono Bridge Mode.
IMPORTANT NOTICE: Although a speaker will operate with the positive and negative leads plugged into either terminal on the amplifier binding
post, be sure to plug the negative lead into the black terminal and positive lead into the red terminal. Ensuring proper polarity will avoid speakers
being out of phase that can cause a loss of bass response.

BANANA PLUG: (Figure 6)
When connecting your speakers to the amplifier using banana plugs, be sure that the red and black caps on
the binding post are completely screwed in. Insert the banana plugs into the caps of the binding post, be sure
that the banana plugs are inserted securely to avoid the risk of popping out.
BARE WIRE CONNECTION: (Figure 7)
When connecting your speakers to the amplifier using bare wire, unscrew the red and black caps on the
binding post, be sure not to completely remove or unscrew the red and black caps. Strip back the wire
insulation 1/2” (13mm). Insert the bare wire into the hole that was revealed by unscrewing the binding post
cap. After inserting the wire into the binding post hole, screw the binding post cap down on the wire. To
reduce the risk of shock or damage to your amplifier, be sure that the wire connected to one binding post
does not come in contact with that of another.
SPADE CONNECTOR: (Figure 8)
When connecting your speakers to the amplifier using spade connector, unscrew the red and black caps on
the binding post, be sure not to completely remove or unscrew the red and black caps. Insert the spade
connector into the binding post and tighten the caps down on the spade connector. To reduce the risk of
shock or damage to your amplifier, be sure that the wire connected to one binding post does not come in
contact with that of another.
MONO BRIDGE CONNECTIONS: (Figure 9)
Mono bridge operation connections will follow the above descriptions, however, when operating in mono
bridge operation the speaker connections will run between the two positive (red) leads, Use channel two
positive output terminal for the negative connection and the channel one positive output terminal for the
positive connection.

Important Precautions Introduction Front Panel Rear Panel Set Up Operating Modes Specifications Protection Features
PROTECTION
SAFE POWER LEVELS AT DIFFERENT OUTPUT LOADS:
8-Ohm Loads: The amplifier can operate at its rated power level without risk of overheating. However, it may caused excessive temperature if it is pushed hard enough
to continually light the “CLIP” indicator, the amplifier's average output power can reach its maximum peak.
4-Ohm Loads: If the “CLIP” indicator flashes occasionally, the amplifier is approaching its Maximum long-term power capacity. If it is lit about half the time,
the amplifier channel will probably go into thermal protection within a few minutes.
2-Ohm Loads: Except for an occasional flash, keep the “CLIP” indicator dark to avoid overheating the amplifier channel. Clipping should be kept to a
reasonable minimum. An amplifier's peak current draw at full output power into 2 ohms is several times what the “normal” draw is, but its various protection
circuits will prevent this condition lasting more than a minute or two.
SHORT CIRCUIT PROTECTION - The PA-500 amplifier comes with built-in Output Short Circuit Protects. The Output Short
Circuit Protection protects the output devices of the amplifier from short circuits and stressful loads. If your speaker lines shorted, the
amplifier automatically detects this problem and discontinued operation for that channel. If one side of your amplifier becomes shorted
and goes into protect mode, the other side will continue to operate normally. During short circuit protection, the “ACTIVE” LED will light
indicating amplifier fault. Channel output during the “Short Circuit Protection” will be interrupted (i.e. no sound output). Short Circuit
Protection can usually be traced back to the signal output line (i.e. speaker line). Check the line from the output terminal of the
amplifier to the speaker. If this line is good, check the internal speaker connections and components. A short circuit will usually be
traced to a bad cable or a bad speaker component and is rarely traced to the amplifier itself.
INPUT/OUTPUT PROTECTION - The input circuits are isolated by resistors. An ultrasonic network uncouples RF from the output and helps to keep the amplifier
stable with reactive loads.
OPERATING VOLTAGE (AC MAINS) - On the rear panel will indicate the correct AC mains voltage. Connecting to the wrong voltage is dangerous and may
damage the amplifier. Always be sure the source voltage for your areas matches the required voltage for your amplifier.
GAIN CONTROLS - The gain controls are located on the front panel and are calibrated in 2dB of attenuation from full gain. It is best to adjust the amplifier so no
“hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion during normal operation.
AMPLIFIER FEATURES
SWITCH-MODE POWER SUPPLY: The PA-500 is designed with SMPS power with CLASS D of Power Stage Topology instead of the traditional toroidal
transformer, therefore the total weight of the amplifier is ultra-light, and also the complete performance is better.
LED INDICATORS: Each channel has three LEDs. One green LED indicates signal, one red LED indicates signal clipping and one red/blue LED indicates
protections mode for shorts/overload.
