QUAD195 QUAD195D MULTI-CHANNEL WIRELESS SYSTEM WITH RF/POWER DISTRIBUTION OPERATING INSTRUCTIONS and trouble-shooting guide LECTROSONICS, INC.
QUAD195/D INTRODUCTION The design of Lectrosonics Quad Pak systems has evolved over the years as a result of suggestions garnered during many conversations with industry sound mixers and production engineers. These suggestions, together with meticulous attention to de sign and construction details, have resulted in a system that offers portability, versatil ity, and “bullet-proof” reliability of operation.
Multi-channel Wireless System GENERAL TECHNICAL DESCRIPTION The QUAD195 consists of two sub-systems; the housing which contains the gel-cell power supply and the RF/power distribution module/s. The housing is constructed of machined aluminum. A strap handle is bolted directly to the top panel of the housing for ease of carrying. The lead-acid gel-cell batteries are connected in series to provide 12 VDC (nominal) power to all the modules installed into the system.
QUAD195/D ANTENNA LEADS - These BNC terminated leads provide isolated RF signals for each receiver installed in the sys tem. ANTENNA - The helical antenna provided with the unit attaches to this BNC connector directly with a twist lock mo tion. Other 50 Ohm antennas may also be used. POWER SWITCH - The power switch has three positions. The OFF position turns off power to all modules in the sys tem.
Multi-channel Wireless System REAR PANEL DESCRIPTION SERIAL/FREQUENCY LABEL - This label indicates the serial number of the distribution module. It also indicates the RF pass-band of the unit. IMPORTANT - The receivers installed in the unit must fall between the frequencies indicat ed on the label. Serious signal loss results if the receivers are outside the RF pass-band.
QUAD195/D The QUAD195 is designed to contain up to four receivers. Installation of these receivers is quite simple. First, loosen but do not remove, the two large counter-sunk phillips head screws in the front panel and the two in the rear panel of the housing. (See drawings on previous pages) Insert the receivers, front end first (the end with the antenna con nection), in through the rear panel. Seat the front end of the receiver into the recessed lip of the front panel.
Multi-channel Wireless System SYMPTOM POSSIBLE CAUSE NO POWER LEDs OR AUDIO 1) Power switch in the OFF position. Switch to MAIN/EXT. POWER LED LIGHTS ON CDM4smt BUT NO LIGHTS ON RECEIVERS 1) Power leads in back not connected to receivers. Check power connections. NO POWER LEDs, ALL CONNECTIONS CHECK OK 1) Gel-cell battery charge too low. Either switch to INT 9V setting on CDM4smt, use an external 12 Vdc power supply, or operate on 110 Vac with the CH-50 charger.

Multi-channel Wireless System We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connec tion, send the unit to the factory for repair and service. Don’t attempt to adjust any controls inside the units. Once set at the factory, the various controls and trimmers do not drift with age or vibration and never require readjustment.
LIMITED ONE YEAR WARRANTY The equipment is warranted for one year from date of purchase against defects in materials or workmanship provided it was purchased from an authorized dealer. This warranty does not cover equipment which has been abused or damaged by careless handling or shipping. This warranty does not apply to used or demonstrator equip ment. Should any defect develop, we will, at our option, repair or replace any defective parts without charge for either parts or labor.
