AUF200S includes two stereophonic balanced A and B channels mixed toward a balanced output. All transitions from one channel to another are performed by an electronic mixing (fade in/out), which the parameters are modifiable. Transitions can be done either by the presence of modulation, or by closing an outside loop, or with a combination of both.

Input/output interfacing:

• "Opto" input
• Relay output showing commutation state.
• Mirror relay output on the input remote control

Four running choices by internal switch programmable. External Sub�-D programming possible too:

• Automatic: modulation on channel B automatically open this channel and disconnect the other one.
• Manual: switching from channel A to channel B by external remote control. Return to channel A by loop opening.
• Automatic or manual: Only one of those previous conditions has to be fulfilled.
• Automatic and manual: both previous conditions have to be satisfied (modulation on channel B and closing of the external loop needed).

APPLICATIONS:

• Insertion of advertisements downstream mixing desks.
• Mixing of advertisements and identification jingles with an unidentified musical program.
• Local program remote insertion on a national program.
• Supervision of the audio modulation presence and in case of absence, management of replacement and automatic back-up.
• AUF is implemented with top quality, extremely well protected output amplifiers which can be used as specialized, long distance shielded or coaxial line drivers.
• The very high bandwidth allows AUF to handle multiplex FM signal.

OPTIONS:

• EE/ET/TE/TT: AUF200S is available in version electronically balanced or Transfo.
• OPT 200: Transformer for balanced input and output(OPT201).
• BYP200: Bypass input A or B directly routed to the output (Security when mains absence).
