TTL55-A
INPUT PANEL
1 XLR INPUT.
2 XLR LINK OUTPUT.
3 DATA INPUT.
This port is used for the network input of RD NET
remote monitoring
4 DATA OUTPUT. This port is used for the network daisy chain output
of RD NET remote monitoring.
5 BY PASS (RESET). This switch by-pass (reset) the last preset loaded
on TTL55A DSP with RD NET remoting control.
6 HIGH FREQUENCY CORRECTION. The combination of the 2
top switches gives 4 possibilities of high frequencies correction
depending on target distance (air absorption correction):
-near field ( up to 25 meters)
-mid field ( from 25 to 40 meters)
-mid far field ( from 40 to 60 meters)
-far field ( more than 60 meters)
7 CLUSTER SIZE.
The combination of the 2 central switches gives 4
possibilities of mid low frequencies correction depending on cluster size:
• 4-6 modules (small flown systems)
• 7-9 modules (medium fl own systems)
• 10-12 modules (medium large flown systems)
• 13-20 modules (large flown systems)
8 ACTIVE NETWORK LED. This led flash when there’s a data
transmission.
9 LINK NETWORK LED. This led is ON when the speaker has been
recognized and connected from the RD NET master unit.
10 RED/ORANGE - LIMITER LED. This led is ON when the limiter circuit
is active to prevent output distortion or damage of the speaker:
- ORANGE - Soft limiter circuit. When the LED is flashing ORANGE one of
the power amplifiers reaches the maximum output for short periods of time
and the working condition can be considered normal.
- RED - Hard limiter. When the LED is flashing RED (following the signal)
one of the power amplifiers reaches the maximum output for longer periods
of time. When the LED is blinking RED one of the RMS limiter circuit is active
in order to prevent damage to one of the transducers or power amplifiers.
Always avoid operating conditions where the System works for
long periods of time with the RED LED flashing or blinking.
11 GREEN - SIGNAL LED. This led is ON when the audio input
signal is superior to -20 dB. When there is no input signal the led is
flashing
12 YELLOW - STATUS LED. This LED is flashing during the
bootstrap procedure and in case of communication problems with the
DSP processor.
13 GREEN - POWER LED. This led is ON when the system is
connected to the AC power source and the main on/off switch is in
position ON.
