1.4.2 Control Units and External Preamplifier
The Control Unit or External Preamplifier is a required component of a CVR installation and functions as
the FA2100 CVR cockpit user interface. Control Units contain a preamplifier printed wiring assembly
(PWA) for interfacing the cockpit area microphone with the FA2100 CVR, and provide a means for
activating the test function via a green push button and an indicator. Bulk Erasure of the FA2100 CVR
storage media is also accomplished by pressing the Control Unit’s red Bulk ERASE push button. All
Control Units contain a headset jack for verifying system operation.
The Model S151/S161, Model S152/S162, and the Model S251/S261 Control Units are for use in
FA2100 CVR ARINC–757 / ED–56A System installations. The Model S151 and Model S251 Control
Units house the Microphone Preamplifier PWA, and have front panel TEST and Bulk ERASE switches.
The Model S151/S251 Control Units are used with an externally-mounted electret condenser-type
microphone (Model S055, see paragraph 1.4.3).
The Model S161/S261 Controls Units are used with remote microphone modules with internal amplifiers
for reducing RF interference (Model S056, see paragraph 1.4.3). These control units also have front
panel TEST and Bulk ERASE switches, TEST indicator lamp and a HEADSET jack.
The Model S152/S162 contains a built-in electret condenser-type microphone, Microphone Preamplifier
PWA, TEST and Bulk ERASE switches, TEST indicator lamp and a HEADSET jack.
The Model S150/S160 Preamplifier is available for FA2100 CVR ED–56A System installations that do
not require a Control Unit. However, because ARINC Characteristic 757 does not address microphone
preamplifiers, the Model S150/S160 Preamplifier is not considered ARINC–757 compliant. The S150 is
designed to be used with the S055 remote microphone. The S160 is used with the S056 remote
microphone.
The FA2100 CVR is compatible with installations using the Model A151B and A152B Control Units;
however, such installations do not comply with ARINC Characteristic 757 or EUROCAE ED–56A. The
