Voice Projector Portable PA System GENERAL DESCRIPTION The VP18R is designed for “wide angle” sound coverage. The natural tone quality of the cone type speaker used in this unit is ideal for indoor applications. The VP18R will work fine outdoors, however, the audience coverage will be more limited than indoors. The unit comes with a hand-held dynamic cardioid microphone, a 16-foot coiled microphone cord, carrying strap and charger.
CONTROLS AND FUNCTIONS The on/off switch on the microphone body controls only the microphone output. It does not switch the power on or off on the main unit. Current is being drained from the battery pack whenever the red indicator lamp is lighted. VOLUME - ON/OFF This knob is used to switch the power on or off on the main unit. The PWR lamp will light when the unit is turned on, but does not indicate the charged status of the battery. It is more of a reminder to turn the unit off after use.
Voice Projector Portable PA System OPERATING INSTRUCTIONS 1. These systems are normally supplied with an M121S dynamic cardioid hand-held microphone. If you are using the hand-held microphone, insert one end of the microphone cord into the microphone, and the other end of the cord into the 1/4 INCH JACK on the control panel. 2. If you are using a Lectrosonics headset microphone, plug it into the MINI JACK on the control panel.
TROUBLESHOOTING GUIDE BEFORE GOING THROUGH THE FOLLOWING CHART, BE SURE THE BATTERY PACK IS FULLY CHARGED. The POWER LAMP should light up when the unit comes on. The POWER LAMP will grow dim as the batteries discharge. Because of the nature of nicad batteries, the batteries may fail during use or be permanently damaged by the time the POWER LAMP is dim enough for you to notice a change. Keep the batteries fully charged when not in use to insure long battery life.
Voice Projector Portable PA System DISTORTED SOUND FROM SPEAKER 1) Volume set too high. Reduce volume control. 2) Excessive wind noise or breath “pops”. Use windscreen on mic. 3) Batteries very low. As the batteries discharge you have to turn up the volume. When the volume knob is turned all the way up and you’re still not getting much volume out of the system, the amplifier is being driven to its limit so it produces a distorted sound. EXCESSIVE FEEDBACK 1) Volume too high. Reduce volume control.
