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. Repeat
this for each receiver to be installed. After all receivers are in place, hold them in postion and tighten the front panel
screws first. These screws should be fairly snug but excessive force should be avoided and is unnecessary. You
are compressing a natural rubber tension tube. Tighten the rear panel screws last. Press firmly on the front of each
receiver to be certain that the receivers are secure.
At the front panel, attach the antenna leads to each receiver, making sure the BNC connector is securely and twisted
and locked into place. Set the power switch on the receivers to the EXT position. Antenna leads serving empty slots
do not need to be terminated.
At the rear panel, insert the power connectors into the power jack of each receiver. Note that the battery compartment
of each receiver may still be opened. It is recommended that each receiver have a fresh battery in place to serve as
backup power in the event that the internal battery pack or external power source fails for any reason.
OPERATING INSTRUCTIONS
After all the receivers have been installed, check to be sure that the receivers have their power switch set to EXT. Au
dio leads should be balanced audio cables leading to the mixer or recorder.
Turn the system on by switching the power switch on the distribution module to MAIN-EXT. The power indicator LEDs
should light on all the receivers and the distributon module/s. If the internal gel-cell batteries are the power source,
the 12V LED will light. If the charger is connected and plugged into an AC source, the AC, 12V, and perhaps the
CHARGING LEDs will be on as well. If the power source is an external 12 VDC power supply, the EXT LED will be on.
Operate the wireless microphone according to the instructions included with the wireless systems.
After use, recharge the batteries immediately to prolong their life. The system incorporates industrial quality gel-cells
which can be left on charge indefinitely without damage (the charging circuitry will automatically limit the current flow
to the batteries). There are no “memory” problems with these batteries. The CHARGING LED will activate to indicate
the batteries are charging and will extinguish when the batteries are at full charge.
The external 12 VDC power supply may be connected to the system through the 4 pin XLR connector on the rear
panel. The connection is made by supplying the voltage through pins 1 and 4. Polarity is not critical since each
receiver contains a diode bridge at their external power input. When an external 12 VDC supply is used the EXT LED
activates. The internal batteries are automatically bypassed by a relay.
In emergencies, the system may also be operated from the internal 9V alkaline batteries in the individual receivers
and the distribution module/s. Switch all units to the INT power switch position. Operating time should be about 4 to 5
hours with an alkaline battery, 8 to 10 hours with lithium (see receiver instruction manuals for accurate operating times
with the receivers).
