HA80
1. Volume Control -
This controls the volume for each channel and sends the signal to the master mix bus. Typical operation
is between 4 and 8, depending upon the device(s) on the channel. Please remember that this acts like a preamp, so if you are
using a device that has a volume output control (i.e. an MP3 player or CD player) you will need to do some level matching by
adjusting the level controls on each unit.
2. Tone Control -
This adjusts the overall tone for the output of the channel. It is set at 5 kHz. Since it is a cut or boost control
(+/- 15 dB), it will add or diminish the presence of the sound’s content around that frequency.
3. Effect Control -
This is a send control to the Effect, sending the signal from each channel to the delay effect. The output
of the delay is blended back in with the mixer’s overall output using the master effect knob (7).
4. 3 Pin Low Impedance Microphone Input -
Phantom power (1.5 volts) for condenser microphones is consistently available.
Input has an impedance of 1k Ohm. The connector is wired as: Pin 1 = shield; Pin 2 = positive (hot); Pin 3 = negative (cold)
5. 1/4” Line/High Impedance Input -
This input can be used as an input for either a high-impedance microphone or line level
device, like a guitar, keyboard or sampler. It is a 2-conductor input with an impedance of 10k Ohms. Both the high and low
impedance inputs may be used simultaneously.
6. Master Volume -
This controls the overall volume level of the entire amplifier. Typical operation is between 4 and 8.
7. Master Effect -
This controls the level of delay effect added back to the overall mix.
8. Aux Volume -
This controls the level coming in from the Aux In RCA plugs on the unit’s back panel.
9. Master Low -
This controls the overall amount of bass frequencies (100 Hz), al/- 15 dB of boost or cut.
10. Master Mid -
This controls the overall amount of middle frequencies (1.5kHz), al/- 15 dB of boost or cut.
11. Master High -
This controls the overall amount of high frequencies (10kHz), al/- 15 dB of boost or cut.
12. Power -
This switches the unit on or off. When the unit is powered up, a red LED will illuminate.
