1. GENERAL DESCRIPTION
The TOA wireless microphone WM-3310 is of lavalier type and is designed to conform with the regulations.
It employs an optimized PLL-synthesizer and a compander noise reduction circuit to minimize the influence of
ambient RF noise.
2. FEATURES
(1) Up to 6 operating frequencies are made available for selection.
(2) An optimized PLL-synthesizer minimizes the oscillation frequency drift resulting from the ambient
temperature or voltage fluctuation.
(3) The sensitivity trim pot control optimizes the system in any locations.
(4) Battery lamp indicates battery consumption to prevent the unit from malfunctioning when the battery level
remarkably decreases.
(5) The compressor and low-pass filter on the audio circuit protect the unit against out-of-band energy
produced by overload.
(6) Chip components make the unit smaller in size yet more reliable.
(7) 6 frequencies of 169 - 216 MHz
3. SPECIFICATIONS
Model No. WM-3310
Oscillator Crystal-controlled PLL-synthesizer
Nominal Frequency 6 frequencies of 169- 216 MHz
RF Power Output Less than 50mW
Modulation Frequency Modulation
Nominal Supply Voltage 9.0V
Usable Battery 6LR61(9.0V Alkaline)
Marginal Battery Voltage Level Approx. 6 V (When the battery voltage falls below this level, the battery
lamp begins to flash.)
Antenna Wired Antenna
4. TEST CONDITIONS
(1) Modulation and Non-modulation
[Modulation]
To perform continuous modulation, connect the plug of the jig supplied with the microphone sample to CN1
and the jig output to an AF signal generator. Then, connect the jig output to an AF oscillator using the shielded
or coaxial cable. For connection, refer to the figure below.(Since the phantom power is present at the HOT
side of the plug, a capacitor to block a DC current is connected to the HOT side.)
