1.2 Application
The IC6100, IC Amplifier Unit, is part of the Digital Voice Communication System DVCS6100 and is
provided for installation in aircrafts and helicopters. Together with the ACU610X Audio Control Units
and the REU6100 Remote Electronic Unit, the IC6100 complement the intercom system of the
aircrafts and/or helicopters, in cases when it is needed more operators positions.

1.3 General Description
1.3.1 Mechanical Description
The IC6100 IC Amplifier Unit is designed for installation in the avionics compartment of an aircraft.
The IC6100 IC Amplifier Unit is a device in standard ¼ ATR short case.
Two unit connectors are fitted on the front and two unit connectors on the back side. The IC Amplifier Unit consists
of the following circuit boards:
•Dual-Headset Amplifier Board (max. 3 ea.),
•Analog Board,
•DSP Board,
•CPU Board,
•Bus Board,
•Connector Board.
1.3.2 Electrical Description
The IC6100 IC Amplifier Unit is an Intercom System, software configurable and accordingly influences and
processes all incoming and outgoing audio signals from the headsets and from IC Ring, performs the logical
functions necessary for aircraft intercommunication and provides the creation of up to 2 IC Ring groups which
can communicate together or isolated at will, by using the Alert Tone activation Line #2. Also allows the
generation of up to 8 different aural tone signals which may be activated through discrete control lines, which can
be used as HOT MIKE lines (up to 6 as Hot mike) or Alert Tone activation lines (alert tones from 3 to 8) and 2 as
Alert Tone activation lines or one as alert tone (#1) and the other as ISOLATION line (#2).
The IC Amplifier Unit provides the following features:
6 balanced SW configurable audio fixed inputs
•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.
•
•6 control inputs for specific logical IC-action.
•3 control outputs for specific logical external activations.
•8 alert tone activation inputs (active low).

•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.

•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.
•Relay controlled fall-back in case of emergency operation (Back up): Fix 1 to headset 1, and Fix
2 to headset 2 (intercomunication between headset 1 and headset 2 remains) . Back-up
operation can be iniciated manually by using an external hard-wired switch, or automatically upon
power supply failure to the IC Amplifier Unit, or, if any internal power supply of the Unit itself is
defective.
The audio processing circuits are realized in a modular design.
Pict. 1: External Memory EM6100-(XXX)
The EM6100-(XXX) is the memory device (optional). It is a small device connected to the IC6100 and
stores all system configuration parameters. It allows a quick field replacement of the IC6100 without
reconfiguration when replacing by a new IC6100.

All data for IC Amplifier Unit are stored in the IC6100 itself and EM6100, if connected. If control elements on
the SW are altered, a data transmission immediately takes place to the IC Amplifier Unit. Saving the current
configuration is necessary for permanent validation. The software was classified as level C in accordance with
EUROCAE / RTCA document ED-12B / DO-178B.
