DESCRIPTION
PRT668 is designed for simultaneous translation in radio and TV. It features:
One ultra low noise microphone preamplifier with input level control and three line level
balanced outputs. Option : 48V phantom supply.
In simultaneous translation, the same people translate the two languages, language 1 to
language 2 for the foreign guest and language 2 to language 1 for broadcasting.
PRT668 features 2 lighted switches with memory to switch the two language outputs. Actuating
one of the switches, enable the require audio, and disable talkback.
Two GPO loops one for each channel, allow remote control.
A fugitive talback key, allows the translator to send order to the control room, using a third
output. When pressed this key cuts the other outputs, return to normal on release.
A GPI allows to send an external control to mute at the same time the two languages output (1
and 2). This is the case when an talkback matrix is used in the translator room.
An ON AIR indicator, enabled by the PRT668, or from the control room.
One balanced stereo program input to feed the embedded headphone amplifier.
The headphone amplifier features a volume control and a balance between the external program
(return from control room) and the signal from the microphone. Some translators prefer to hear
themselves, others no.
An talkback system, with program fade. Fade is activated by order signal or external loop or both.
Talkback
can be sent to both earphones, or either left or right. A unique Sub D 25 eases fast integration.
