Front Panel
1. Power Switch
This switch turns the AC Mains power to the amplifier on or off.
2. Power LED
Illuminates Red when the power switch is depressed. Red means the amplifier has AC mains power to
the unit and is standby or sleep mode. When LED is Blue the unit is active and will pass audio.
3. Limit LED
The Limit LED will illuminate Red if either channel of the PA702 reaches maximum output power or if
a fault is detected with in the amplifier. The PA702 features a true limiter circuit which help prevents the
amplifier from hard clipping or from being over driven. An occasional flash of the LED is OK, if the LED
is on continuously reduce the input level of the amp. After the reducing the input level and the Limit LED
remains on, recheck the load connections to the amp.

to increase and counterclockwise to decrease the signal level.
6. Bass Control
Normally set at the 12:00 position unity gain, rotating clockwise will increase (boost) bass frequencies to
a maximum of +6dB at 100Hz. Rotating counterclockwise from the 12:00 position will decrease (cut) bass
frequencies to a maximum of -6dB at 100Hz. Note: This feature affects both the Left and Right Channels
the same.
7. Treble Control
Normally set at the 12:00 position unity gain, rotating clockwise will increase (boost) treble frequencies
to a maximum of +6dB at 10kHz. Rotating counterclockwise from the 12:00 position will decrease (cut)
