GENERAL DESCRIPTION
1.1
INTRODUCTION
This publication provides operating and installation information on the Model TAC-200A,
Dual Audio Controller manufactured by Technisonic Industries Limited. This unit is designed
to provide high performance operation for installations requiring two completely independent
audio controllers in a single panel mounted box. The pinout configuration of the rear
interconnects, is optimized for superior operation specifications, and is plug and pin
compatible with the ACCESS/A family of products.
1.2
DESCRIPTION
This high power audio controller delivers 500 mW of audio per side into 600 ohms at less
than 2% distortion. Separate pilot and co-pilot transmit selector switches allows either
operator to select any of the five aircraft communications transceivers or PA amplifier, while
an audio input selector switch for each input allows selection of any combination of, or all,
of the eight available aircraft audio inputs.
The TAC-200A has front panel selectable and adjustable VOX, LIVE or KEYED intercom
(ICS). An EMERGENCY mode switch provides “straight through” transmit and receive audio
for the pilot on the selected communications channel. The ISOLATE switch allows the pilot
to isolate himself from the co-pilot (and the ICS system), so that he and the co-pilot may
access different communications at the same time. In the NORMAL position, the pilot’s
audio is provided as selected by the co-pilot and is part of the ICS system. Separate RX and
ICS volume controls are provided on each side of the panel along with a single ICS VOX
threshold control. The TAC-200A will also provide ICS support for up to seven headsets.
1.3
PURPOSE OF THE EQUIPMENT
The TAC-200A Dual Audio Controller is designed to provide centralized audio management
and control within an airborne communications environment. The unit has been packaged
to minimize size and weight characteristics and is ideally suited for helicopter installations.
The TAC-200A meets all of the requirements of US Forest Service “contractor furnished
avionics” and can be used in conjunction with a TiL FM airborne transceiver to comply with
all US Forest Service Contract Requirements. The product is also compliant with DO-160C
categories relating to frequency response, cross-talk, vibration, humidity, temperature and
altitude in an airborne environment.
1.4
MODEL VARIATION
The TAC-200A comes in two possible configurations. A +28VDC panel lighting version
and a +5VDC panel lighting version. Operationally the two are identical. The default is
+28VDC backlighting. The backlighting is achieved through solid state devices, and
produces virtually no heat and a light wavelenght of approximately 580nm. The front panel
background colour itself, is a choice of either matte black or Cessna cadet grey. Default is
black. See TAC-200A price list for model variations.

SECTION 2
INSTALLATION INSTRUCTIONS
2.1 GENERAL
This section contains information and instructions for the correct installation of the TAC-
200A,
Dual Audio Controller.
Make certain that the unit is correctly operating in accordance with the equipment user’s
requirements prior to releasing the equipment for service.
2.2 EQUIPMENT PACKING LOG
Unpack the equipment and check for any damage that may have occured during transit.
Save the original shipping container for returns due to damage or warranty claims. Check
that each item on the packing slip has been shipped in the container. Verify that the
equipment’s backlighting configuration is the same as that required.
2.3 WIRING REQUIREMENTS
Airframe wiring should be MS22759 Tefzel or Raychem 44 (81044) single conductor and
shielded wire. Heatshrink solder sleeves (such as Raychem or equivalent) should be utilized
for shield termination.
All Microphone audio input line connections should be made with Shielded Cables. Audio
output lines may be twisted pairs. The power cables should be a minimum of #22 AWG.
Keying lines may be #24 AWG
DO NOT bundle low level audio lines with RF coaxial cables, motor, pump or blower wiring
which can cause coupling between the various systems, especially during RF transmission
or pump\blower mechanical operation. Maintain as much distance as possible from these
types of wire bundles.
2.4 AUDIO PANEL INSTALLATION
The TAC-200A Audio Panel is designed to be Dzus mounted and should be installed in
conjunction with installation kit P/No. 969732. See Figure 2-1 for and outline drawing of
the unit with dimensions to facilitate the installation.
All configurable and variable options of the TAC-200A can be set or changed simply and
without requiring the opening of the unit.
