Plug the AC/DC adapter (provided) into the 9VDC INPUT JACK (3) on the back of the receiver. Then plug the power supply into an AC outlet. Switch the POWER (1) to the ON position. The POWER ON LED (2) will now light and the receiver is operational. 2. Rotate and extend ANTENNAS (4) fully, angled at 60° position as shown. 3. The 1/4" AUDIO OUTPUT JACK (5) provides a fixed, unbalanced MIC level audio output for connection to your mixer with the 1/4" to 1/4" cord supplied. As when making any connection, make sure the mixing board's volume is at the minimum level before plugging in the receiver to avoid possible sound system damage. [Note: this output is the sum of the signals received by both the internal receivers (CH 1 + CH 2). Use the CH 1 & CH 2 VOLUME CONTROLS (6) to adjust the individual relative channel volumes.] OPERATION (11) (10) (9) (8) HANDHELD MIC TRANSMITTER 1. Unscrew the BATTERY COMPARTMENT COVER (8) and remove. Insert a fresh 9V BATTERY (9), observing correct polarity as marked, and screw the cover back on to the microphone. To ensure proper battery contact, the cover must be screwed on completely. 2. Turn on the handheld mic by sliding the OFF/ON SWITCH (10) to the ON position. The BATTERY INDICATOR LED (11) will give a single quick flash, indicating usable battery strength. In the case of a dead or low battery, the LED will either not go on at all or will stay on continuously, indicating that the battery should be replaced with a fresh one. 3. The microphone is now ready to use. The corresponding Rx LED (7) on the DKW-DUO receiver should now be lit, indicating a received signal from the transmitter on that Channel (1,2). Adjust the VOLUME (6) control of the receiver channels you are using clockwise to about 3/4 rotation, until the volume level is comfortable for your application. If using both CH 1 and CH 2, adjust the relative volume of each channel as desired in the mixed (summed) receiver AUDIO OUT (5). [Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic feedback (howling or screeching) will be avoided.] SPECIFICATION OVERALL SYSTEM PERFORMANCE Frequency Response: 80-14,000 Hz, +/-3dB Dynamic Range: 95dB Total Harmonic Distortion: <0.7% RF Carrier Frequency Range: 170-216 MHz Frequency Stability: +/- 0.005%, crystal controlled Modulation: FM (F3E), +/-15KHz max.
