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.

4.Left & Right Signal LED’s

The Signal LED’s illuminates Blue if there is audio signal present at the input of the amp.

5.Left & Right Input Gain

The Left and Right rotary control varies the amplitude of the signal fed into the amplifier. Turn clockwise 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) treble frequencies to a maximum of -6dB at 10kHz. Note: This feature affects both the Left and Right Channels the same.
