Introduction  
The Bogen Enhancer is an infrared wireless microphone system offering professional performance and  
operating features. Infrared transmission is used to reduce room-to-room interference while sending a sig-  
nal from a presenter’s microphone to a dual-channel receiver.The receiver works in tandem with an  
amplifier and speaker(s) to reduce the effects of poor room acoustics and the weakening effect of voice  
traveling through air.

Connecting the Audio Output  
The BCWR Receiver provides an unbalanced, line-level mixed output to the RCA Jack (3).This can be  
connected to a mixer or a P.A. system using the supplied RCA to RCA audio cable.The audio of both  
Channels A and B are mixed together at this output.The Channel A and B mix is dependent on the sepa-  
rate Channel A and Channel B Volume Control (4) settings located on the back panel of the receiver.  
Always make sure the mixer/P.A. volume is turned to minimum before plugging the audio cable into the  
receiver or before turning the receiver ON/OFF (if the audio cable is already connected) to avoid possible  
sound system damage.  
Connecting the BCIRS IR Sensors  
Connect the BCIRS Infrared Sensors to the BCWR Receiver by plugging both sensor coaxial-type plugs  
into the Infrared Sensor Inputs (5). Each sensor input will receive both Channels A and B.  
Powering the Receiver  
Using the AC Power Adapter, connect the AC Power Input (6) to an AC outlet (110-120V AC).Turn  
ON the BCWR Receiver using the Power Switch (1).The IR Reception LED Indicators (2) will now  
light either green or red, depending on whether the corresponding transmitters are ON or OFF.

BCIRS Infrared (IR) Sensors  
Operation  
The IR Sensors act as "antennae" for your infrared  
wireless microphone system.A multiple array of  
wide-angle IR-sensitive LEDs (behind the front  
panel receptors) receive the infrared signal emitted  
by your IR Transmitter. Connect each BCIRS Sensor  
to the rear jacks on the BCWR (labeled IR In),  
then turn the BCWR Receiver ON.The Sensor  
Power LED (1) will light to indicate that the sen-  
sor is properly connected to the BCWR Receiver.  
The Channel A and B IR LED indicators will light  
green when an infrared signal on the corresponding  
channel is detected.

Installation  
The BCIRS Sensors can be mounted on any surface  
using any of the Mounting Brackets (2) and  
screws, included.To ensure proper operation, observe the following installation rules:  
a. Position the IR Sensors with their front panel receptors facing the entire area of transmitter operation.  
If this is a wide area, angle the receptors to cover the maximum area range.  
Note:The IR sensors will need to be positioned differently for each environment. During installation, power up the  
Bogen Enhancer System and have one person walk around the desired location, with the transmitters on, while  
another person positions the IR Sensors for greatest range of mobility.  
b. Since the unit utilizes infrared light reflected off of room surfaces, do not mount the sensors near a  
black ceiling, wall, or heavy curtains as they may limit the range by eliminating such reflections.  
c.Although the unit can be used in most brightly lit rooms, it works best if bright lights do not shine  
directly on the sensors. (Note: System is not designed for use in high ambient light conditions such as out-  
doors in sunlight or on stage with strong stage lighting.)  
d. Never cover the IR Sensors as this will disrupt normal operation. If they become dirty, clean with a soft  
cloth. Make sure the sensors are not obstructed and always have a clear line of sight to the transmitters.  
e. Position sensors and wires away from Plasma TVs and other equipment that may produce high levels of  
electrical and RF interference.  
Note:Additional BCIRS IR Sensors can be added using the BCYA Multiple Sensor Adapter which allows multiple sen-  
sors to be connected to each input.

position.The two-color Power ON/LOW Battery LED Indicator (7) will light green, indicating that  
the transmitter is ON. In the case of low power batteries, the indicator will light red, indicating that  
the alkaline batteries should be replaced with fresh ones or the NiMH batteries should be recharged.  
(Note:The Rechargeable Battery Pack should only be charged with the Battery Charger listed. Never attempt to  
recharge alkaline batteries.) The optional BCBRA Recharging Adapter can be plugged directly into the  
BCWBT DC Input Charge Jack (8) from an AC power outlet for easy charging of NiMH batteries.  
When the recharging adapter is plugged in, the recharger’s LED Indicator will light red. The LED  
Indicator will light green when the batteries are charged. (Note:Always remove batteries from the BCWBT  
Transmitter when not in use.)  
c.The BCWR Receiver's IR LED Indicator of the corresponding channel should now be lit green.While  
wearing the microphone and speaking, slowly increase the BCWBT’s Volume Control (5) and adjust  
the volume control on the receiver, and also on the Mixer/P.A. to the desired level while taking care to  
avoid acoustic feedback.The microphone is now ready to use. For optimum performance and range,  
make sure that the IR Emitter (4) is not covered by the body or clothing and has an unobstructed  
line-of-sight with the IR Sensor.  
Note: Observe care in selecting volume, transmitter location, and speaker placement so that acoustic feedback  
(howling and screeching) will be avoided.
