•Volume Control configurable by software
•Amplification of summed audio signal to 250 mW into 300 Ω or 500 mW into 8 Ω.
•Conditioning of mike audio to 50...400 mV into 150 Ω (standard carbon mike) or 0.5...4 mV into
20 Ω (dynamic mike):
- Automatic Gain Control (AGC).
- Providing the standard mike BIAS voltage supply.
•Generation of a sidetone for the IC.The sidetone is SW configurable (all headsets at the same time).
•Conditioning of mike audio for intercom operation:
- Enhancing to IC Audio Line level 0.775 V into 600 Ω.
- Intercommunication VOX level control by software.
•Addition of an incoming IC audio signal to the summed-up monitor audio; adjustment of the IC audio
level via the SW program by 0 .... -48 dB.
•Interconnection and separation of the IC circuits by using a dedicated alert tone line.
Winchman Individual VOX level adjust is performed via discrete control lines (#1)
If the VOX level push button is pressed for a short time (0.3s to ≤ 3s), the VOX level is increased
by one step, until the maximum value is reached. If the VOX level push-button is pressed for a
time ≥ 3s, the VOX level will be reset to the value set on the corresponding SW location.
•
lnput definition for VOX-level adjust line will be as follows:
- Single click:
Active LO, Input voltage ≤ 1 V (min. LO time 0.3 s, max. LO-time ≤ 2 s)
- Reset click:
Active LO, Input voltage ≤ 1 V (LO-time > 3 s)
•Generation of up to 8 different alert signals (1 continuous, 3 pulsed, 4 intermittent) in the
frequency spectrum of 1200 … 4800 Hz. The quantity is depending on the total of HOTMIKE lines used.
Both functions can not happen at the same time.
These alert tones are activated via 8 discrete control lines (active LO ≤ 1 V) and addition of
those signals to the summed IC audio signal.
Via configuration software it can be set which of the alert signals are:
- Muted individually in each
- Headset set at the priority level
- Set at cancellation possibility
•Interface facility for IC Amplifier Unit configuration.
•Initialization of a system selftest upon power-on (P_BIT) , a background test routine is continuously
running (C-BIT).
•Provision of 2 alternative internal operation voltage(s) from either of the airframe power supply buses.
