Adcom GTP-740 - Manual (Page 14)

20 Digital RF Demodulator bypass switch
(see illustration on preceding page)
This switch adds flexibility to the GTP-740. If you play laserdiscs with Dolby Digital-encoded
soundtracks, put this switch in the IN position. This places the demodulator circuit in the signal
path and allows proper Dolby Digital decoding.
If you do not have a laserdisc player with a digital RF output, place the switch in the OUT position.
You can then use this input in exactly the same way as you would use the DVD input.
21 12 volt trigger output
(see illustration on preceding page)
To facilitate remote turn-on and turn-off of other components (power amplifiers, for example), this
2.5 mm mini-jack provides a constant signal (12 volts DC) whenever the GTP-740 is fully
powered. When the GTP-740 is turned off (via the front panel switch) or placed in standby mode
(via the “power” button on the remote controller), the jack has no output.
22 Analog Audio and Standard (Composite) Video inputs and outputs
LD (laserdisc) inputs:
Use these inputs as you have already used the digital source inputs (see #19 above.)
After selecting and connecting the laserdisc player’s composite video output to the GTP-
740’s yellow-center RCA jack immediately under the “LD in" label, connect the player’s
left channel analog audio output to the white RCA jack under the “LD In” label. Then
connect the player’s right channel analog audio output to the “LD in" red RCA jack.
