Thank you for purchasing the Dukane Wireless Microphone System
WMIC1. This system operates using digital voice coding which is transmitted by radio frequency signal
at 2.4GHz.
The system consists of a small lightweight transmitter into which a headset, lapel or other mic can be
plugged. The transmitter unit has a lanyard or cord so it can be worn around the user’s neck.
The wireless radio frequency, RF, signal is sent to a receiver unit that can be placed somewhere in
the room. The receiver is typically near a audio amplifier. Or the receiver can be placed on or near a
projector which has a “mic input”. The projector can then amplify the signal for it’s internal speakers.
Inside the projector the signal can also be switched and mixed with other audio inputs. Furthermore
the projector can control the volume level and the signal can be obtained from the audio output for use
with external amplifiers and speakers.
The range for the mic transmitter is about 100 feet. The system can operate on any of 80 selectable
channel frequencies. The channel is set by the receiver and visible on the LED numeric display of the
receiver. The channels range is from 2.400 to 2.480 GHz starting with 2.401 and increasing in 0.001
steps to 2.480 GHz.
Upon initial operation the transmitter is paired to the preset receiver channel by bringing the mic trans-
mitter within about 6 ft. of the receiver. Once paired the system can operate at the full range. Due to
the many channels available, other identical mic systems paired to a different channel can operate in
close proximity.
The transmitter has a red LED to indicate low battery charge, and a green LED to indicate the “paired
to receiver” status. A flashing green LED on the transmitter or receiver means the system is “seeking a
device” for pairing.

FCC Statement: DECLARATION OF CONFORMITY
Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interfer-
ence received, including interference that may cause undesired operation.
Radio Frequency Interference Warnings & Instructions This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is encouraged to try and correct the interference by one or
more of the following measures:
Reorient or locate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.

SETUP
1. RECEIVER
Screw on the long antenna ( see 10 below). The receiver audio output (6 below) is via a
3.5 mm mini plug on the front of the unit . Connect this output to an amplifier or the MIC
input of a projector.
The audio out is at line level, so if connecting to a Dukane projector set the MIC
LEVEL to HIGH. This is found on the projector at ADVANCED MENU then AUDIO /
MIC LEVEL / then HIGH. For the projector set the volume to about mid-range.
The receiver is powered by a DC voltage from a power adaptor (5V ,500mA) which is
next plugged into a 115 VAC power line outlet. The adapter connector is plugged into the rear of the re-
ceiver, (see 13 below).
Next turn the power switch to ON (12 below) on and switch (11 below) to “20 dB / mic” you will see green
LED light “Status” (3 below) begin flashing.
The NUMERIC LED display (5 below) may light up with the “01” . This display shows the Channel number
or the Volume level of the receiver. For initial setup the volume can be set to about mid range at 17 ( Vol
Range is 0 to 31) . The Ch (Channel) can be set to avoid another know system channel ( channel range is 1
to 80). For initial operation any channel may work.
Note the green “Status” LED ( 3 below ) on the receiver continues flashing.

2. TRANSMITTER
Wireless microphone transmitter (cream colored plastic unit)
Attach an antenna.
First open backside compartment and insert the Li-battery into transmitter. Line it up
with the contacts in the compartment.
Next connect a microphone unit to the transmitter via the 3.5mm mini jack port on
the transmitter top. Use either the headset mic or the clip on mic.
Using the left side power button ( see 8 below) hold it down for 3 seconds to turn ON the
power. The indicators will flash red and green.
After power is ON the green LED ( signal indicator light) will continue flashing.
If the red LED is flashing or remains ON, the battery needs to be charged.

3. Pairing; Bring the transmitter close to the receiver ( within 3 ft if possible ). After a short time
the transmitter will lock to the receiver. When this happens the transmitter light will remain ON, a solid green.
The green receiver LED will go out.
No light on the receiver means it is locked to a transmitter. ( Or the power is off )
The mic should now be active.
The range extends to 150 ft. and through solid objects.
The “Vol +/- “ buttons on the right side of the transmitter will change the mic sensitivity and the resulting sys-
tem volume. One suggestion is to set all levels at the midpoint and adjust from there. Remember the Re-
ceiver also has a Volume adjustment.
For projectors there are also a “Mic Vol “ and the Output “Vol” controls. Also, the internal projector speaker
can be set in the ON or OFF state.
Please note that the headset microphone is a little more sensitive than the clip-on lavaliere type mic. The
transmitter can be worn by placing the lanyard ribbon around the user’s neck.
System operation.
The system operation uses 48k digital audio sampling. There are 80 channels available for the transmitter and
receiver. The frequency of operation is 2.400 to 2.480 GHz.
Channel changing; Changing the channel on the receiver will cause the transmitter and receiver to loose
their lock. The receiver channel can be set using the Ch + or - buttons.
Please turn the transmitter OFF for about 10 seconds. Then turn it back on and the transmitter green LED will
flash till it locks to the receiver. The receiver LED will also flash till the lock occurs and then it will go OFF. A
flashing green LED indicates the system components are seeking a pairing..
Turning OFF the transmitter or receiver will require the system when turned ON to again seek and pair.
Low Battery;
Operation with a low battery in the transmitter can result in weak signals which will result in noise and loss of
pairing.
A fully charged battery in the transmitter can operate for over 8 hours. The low battery is indicated by a red
LED. The transmitter battery is charged using the line plug adapter with the USB port. Use the USB to 3.5mm
mini jack cable. The battery is a rugged cell phone battery, Nokia BL-5B Lithium-ion, 3.7V . It is charged by the
5V DC from USB ports.
