(6)POWER CONNECTOR WITH FUSE HOLDER

This standard IEC power cord receptacle is used to connect the AC power to your unit. It features a built-in fuse holder for a 5X20mm, 0.5A/250V slow-blow fuse. If the fuse continuously blows, shut off the unit and have it serviced by qualified service personnel.

CONTROLS & INDICATORS

FRONT PANEL

The PRA-8 has eight independent pre-amplifier channels. The unit provides variable rotary gain controls, phantom power and peak indicator lights per channel.

(2)GAIN CONTROLS

Each channel features a rotary gain control for variable adjustment of the desired pre-amplifier level.

(3)PHANTOM POWER SWITCHES

If needed to power condenser microphones, each channel features a phantom power switch for supplying +48VDC across pins 2 and 3 of the XLR input connector. If you don’t need phantom power, be sure to turn this switch to the “OFF” position.

(Note, It is safe to connect balanced dynamic mics even if this switch is on, but connecting unbalanced devices or devices whose transformers are center grounded will cause hum or malfunctions. Shorting the +48VDC can also damage your PRA-8. Also, mute any connected Monitor/PA speakers when turning the phantom power on or off.)

(4)POWER LED INDICATOR

This LED indicator illuminates when the unit is powered on by the rear panel POWER SWICH (8).

(9)CHANNEL PEAK (CLIP) LED INDICATORS

This LED indicator illuminates when that channel’s pre-amplifier is overloaded. To avoid distortion, turn down the GAIN (2) control for the selected channel until the peak clip light is no longer illuminated.

REAR PANEL

(8)POWER SWITCH

To turn the unit ON or OFF, press the upper or lower portion of this button as indicated. The front panel POWER LED INDICATOR (4) will illuminate when the power is “ON”. Before turning on this unit, verify connection to the proper voltage AC source, check all connections and turn down the level controls of equipment connected to the outputs.

(6)AC VOLTAGE SELECTOR SWITCH

Before plugging in the power cord, check to see that the unit is set for the proper voltage for your area: ~115v (60Hz) or ~230V (50Hz).

(Note: use at the improper voltage can damage your unit and void the warranty.)
