GENERAL DESCRIPTION
• The MAW-201 modulator generates double sideband, mono sound TV channels of the
systems B/G/D/K/I/L/M/N/Australia.
• Appropriate use with TV satellite receivers, VCR’s and video cameras.
• Possible connection of stereo sound sources. L and R signals are
summed by the modulator itself.
• Panel potentiometers for audio modulation and RF output level settings.
• Indoor mounting.

INSTALLATION INSTRUCTIONS
- Read the safety instruction first.
- To change the modulator settings, open the plastic cover.
- If RF IN connector on the modulator is not used, connect the 75 Ω load supplied.
- When modulators are cascading, space between channels must be no less than two (for example 21, 24, 27 and etc.).
- Fix the box on the wall using two screws through the internal holes.
DEFAULT SETTINGS
1. Output channel E02;
2. Audio subcarrier deviation ±50 kHz (when audio signal level 1 kHz is 775 mV);
3. B/G standard; audio subcarrier 5.5 MHz ( Display b5);
4. Test pattern generator OFF ( Display no);
5. Frequency shift none ( Display 0);
6. P/S ratio -16 dB ( Display 16);
7. Output signal on ( Display on);.
OPERATING
The modulator has two modes of operating:
1. NORMAL: sets after plug in;
Output channel can be selected in normal mode by pressing buttons “-“ or “+” (see tables).
2. SETTING: to enter the setting mode press and hold “-“ and “+” buttons simultaneously for 1 second, to exit
setting mode press and hold “-“ and “+” buttons simultaneously for 1 second.
Select of necessary to change parameter by pressing button “-“ and set necessary mode by pressing “+” button.
1. TV system setting:
a) after switching settings mode, indicator displays current TV system (see table);
b) set necessary TV system by pressing “-“ button (see tables);
c) after TV system changing, modulator sets to first channel of selected TV system (see tables), other settings
remains unchanged.
2. test pattern generator:
a) press “-“ button;
b) switching between OFF and ON by pressing button “+”, “no” - test pattern generator OFF, “t5” - test pattern
generator ON.
3. fine tuning of video carrier frequency:
a) press button “-“;
b) shift video carrier frequency by pressing button “+” (see table).
4. picture/sound ratio switching:
a) press button “-“;
b) switching between 12 dB and 16 dB by pressing button “+”.
5. output signal switching:
a) press button “-“;
b) switching between RF ON and RF OFF by pressing button “+”, “on” - RF ON, “oF” - RF OFF.
PROTECTION FROM UNAUTHORIZED ACCESS
To prevent unauthorized access press buttons “-” and “+” simultaneously twice in 0.5 sec. “LO” will briefly be
displayed. To revert to normal operation, repeat above procedure. “UL” will briefly be displayed. The symbol “LO”
appears, if you try to change settings in locked mode.
SOUND SUBCARRIER DEVIATION SETTING
When input signal level is from 340 mV to 775 mV in both audio inputs, use a regulator to set the sound
subcarrier deviation ±50 kHz. The factory set sound subcarrier deviation is ±50 kHz for an input signal level of
775 mV in both audio inputs.
OUTPUT SIGNAL LEVEL ADJUSTMENT
Use a regulator (figure 1, position 6) to adjust an output level. Output level adjustment range is 0 ÷ -20 dB.
