MMTS20 and other compatible
modular units
The R.L. Drake MMTS20 is an MTS stereo
encoder which accepts left and right channel
audio input and generates a composite BTSC
format stereo signal. The composite signal is
applied to the audio input of a compatible
audio/video modulator. The modular design of
the MMTS20 permits convenient pairing with a
Drake Mini-rack fixed channel or agile type
Video Modulator in a multiple unit rack
configuration.
Rear panel left and right audio inputs allow
either balanced or unbalanced operation. The
MMTS20 must be supplied with the modulator
video in order to provide the MMTS20 with sync
information for the encoding process. A front
panel Audio Level control with corresponding
Overmodulation indicator permits setting the
proper audio input levels to the MMTS20.
A Pilot Lock indicator is provided to verify that
the encoder is properly synchronized to the
supplied video horizontal sync. A built-in audio
test tone generator, turned on or off from a front
panel switch, is provided for calibration of the
modulator Audio Input level.
As previously described, front panel controls
include Audio Level and Test Tone switch. Front
panel indicators are Power, Pilot Lock, and
Overmodulation. A rear panel 'F' type connec-
tor is provided for the video sync reference.
Left and right audio inputs are through rear
panel 3.5 mm 'stereo' type receptacles. The
composite BTSC signal output is through a rear
panel RCA type phono connector. The unit is
powered by a compatible Drake Mini-rack
power supply module.
