PPA-300 PORTABLE SOUND SYSTEM OPERATING INSTRUCTIONS
IMPORTANT SAFETY INSTRUCTIONS The PPA-300 should not be exposed to liquid, nor should items filled with liquid be placed on the device. The MAIN plug disconnects device. Warning: The disconnected device could still have electricity or heat circulating even after being disconnected. Warning: The user should not place this device in a confined area during operation so that the main switch cannot be accessed. 1. Read these instructions before operating this device. 2.
PPA-300 PORTABLE SOUND SYSTEM INTRODUCTION • 8-Channel powered mixer. • Four XLR MIC inputs. • Two TRS stereo Channels with RCA 3.5mm Stereo inputs. • Channels with 3-bend EQ, EFX Sound, Pan, Level. • USB PORT CONNECT TO FLASH DRIVE, MP3 PLAYER. • Effects send on every channel with stereo return. • Internal Digital delay effects processor with 16 selections end foot switch jack, including echo, delay end vocal enhancement. • Effect parameter adjustment allows you to customize each effect selection.
SAFETY PRECAUTIONS The AVTRONICS PPA-300 sound system is supplied with a detachable power cable with an lEG female connector and a male AC connector. Depending on the territory in which the PPA-300 system is purchased, the power cable will be supplied with one of a number of male AC connectors in order to accommodate the different safety and code requirements of specific countries. All AC cables supplied with PPA-300 products are three pin grounded type.
FRONT PANEL –3–
CONTROL FUNCTIONS 1) HIGH - Adjusts the relative level of the high frequency content. Rotating the knob counterclockwise decreases the high or low frequency response. Likewise, rotating the knob clockwise increases the high or low response. 2) MID -Adjusts the relative level of the mid frequency content. Rotating the knob counterclockwise decreases the high or mid frequency response. Likewise, rotating the knob clockwise increases the high or mid frequency response.
18) STEREO / DUAL SELECTOR SWITCH - Allows the PPA-300’s power amps to be configured as stereo or “dual - mode”. In the Stereo mode, the system operates as a traditional stereo power mixer / amplifier. In the dual mode, the channel level controls set the level for the Main mix (LEFT master volume control). The Rev / Aux controls set the individual channel levels for the Monitor (RIGHT master volume control).
28 & 29) AMPLIFIER SEND / RETURN JACKS - Each channel of the amplifier has a Send and Return jack. These jacks provide a point to patch in an equalizer, or other processor into the sound systern. The signal at the send jack is located after the mixer section and before the power amplifier. The send jack should be connected to the output of the external device. 31) SPEAKER OUTPUTS - These are speaker level (powered) output jacks designed to feed each of your PPA300 speaker enclosures.
REAR PANEL –7–
REAR PANEL CONNECTOR / LINE CORD - The PPA-300 is equipped with a grounding type lEG supply cord to reduce the possibility of shock hazard. Be sure to connect it to a grounded AC receptacle. DO NOT ALTER THE AC PLUG. The power main (AC) fuse and fuse holder are under the IEC (power cord) socket. Replacement fuses must be of the same rating (6A 250V) and size as originally equipped. To replace a blown fuse, remove the lEG power cord, pull out the fuse holder and find the spare fuse inside.
SET-UP SYSTEM VOLUME AND LEVELS To set system volume and operating levels, be sure to follow these simple set-up guidelines: I. First, slowly raise the large Left and Right Master volume controls to their 12 o’clock notched positions. 2. Use a microphone (or other source) in the same position as it will be used on stage and in the manner in which it will be used for the event.
SPECIFICATIONS Frenquency Response 20 Hz to 20 kHz 1dB (at send output) 30 Hz to 20 kHz 1dB (at speaker output, with processor threshold exceeded) Distortion <0.05%, 20 Hz to 20 kHz, I dB below rated output System Signal to Noise Ratio >80dB @ 1w. “A” WTD Power Output 150 W/ch continuous average power, 8 ohm, both channels driven with THD <1% Input Impedance (Channels 1-2-3 and 4) “Mic” 2k ohm “Line” 33k ohm Input Impedance (Stereo Channel 5/6,7/8) 33k ohm Max. Input Level Mic: -7 dBu Line: 30 dBu Stereo.
