NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. A The lightning flash with the arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a electric shock to persons. A The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. Description: The JENSEN PA500 is a universal public address system that can be utilized as a stand alone PA (when connected to speakers) or operate in conjunction with any existing radio/speaker set up. Operation: The PA500 system amplifier connects in line between the vehicle's radio and the installed speakers. The installed radio will operate normally. When the microphone is activated by the "Push to Talk" (PTT) switch on the microphone, the speakers are electrically disconnected from the radio and engaged with the PA. The microphone triggers activation of the PA through the same speakers (muting/overriding the radio source). There is no need to adjust PA volume at the radio since the PA volume can be set using the volume/gain control on the PA500 itself. If the PA500 is installed in an enclosure the volume level can be pre-set by the installer.

In this method, the microphone volume may be adjusted or turned on/off to meet the operator's preference. 2 Troubleshooting: Symptom Possible Cause Possible Solution Has audio from radio but not PA500 - PA not turned on - Volume set too low on PA - In-line fuse blown - Input and output wired backwards - Turn PA on - Adjust volume of PA to higher level - Check and replace in-line fuse - Reverse input and output wiring High pitched squeal (feed back) - Volume on PA set too high -Turn volume on PA down Hand held MIC keyed and gets feed back - Volume on PA set too high - Volume on MIC set too high - Turn volume on PA down - Turn volume down on MIC PA500 will not turn on, (does not have power) - In-line fuse on PA blown - Replace fuse Specifications: 4 Channels Current Draw Frequency Response Size Weight 25 Watts per channel, 4 ohm load 7 Amp Max. 100-10,000 3.08" x 1.85" x4.0"(WxHxD) 15 oz. 11 Speaker Connections: 3 Pair- 40hm Speakers Curb Side 6 Ohm Total Impedance Driver Side 6 Ohm Total Impedance Align Speakers with "+" on top and on bottom as shown ©- 4 Pair- 40hm Speakers Curb Side 4 Ohm Total Impedance Driver Side 4 Ohm Total Impedance Right Front Left Front Align Speakers with "+" on top and on bottom 5 Pair- 40hm Speakers Curb Side 4.8 Ohm Total Impedance Driver Side 4.8 Ohm Total Impedance Align Speakers with "+" on top and on bottom Optional Flange Mount Installation: The PA500 may also be mounted in a "blind" location, using the mounting holes on the flanges. In this case, the microphone volume must be pre-set by the installer prior to the completion of the installation. The 30 ft. microphone extension/adapter cable (P/N 1401035) or the 36" microphone extension/adapter cable (P/N 1401040), is to be used to allow connection of a PTT (Push To Talk) type microphone by the operator. 3 Typical Wiring Connections: INPUT NOTES: Wire Radio according to Manufacturer Spec. PA500 can accept any radio (up to 4 Channels). Maintain appropriate load requirements.
