1 Description
The FHA2054 audio transformer kit is for a reliable ground disconnection of the
low-level audio source in booster amplifier station EBA2001. The FHA2054 audio
transformer kit is installed in booster amplifier station EBA2001 and must be
connected to 'Line in' 'X4' at the booster amplifier mainboard (100 W) EBA2004.
The FHA2054 comes with all individual parts for installation.
The kit contains a shield connection terminal block, an isolating transformer
module with connector for the low-level audio connection, a terminating resistor for
supervision and a terminal block for the wiring to the low-level input.
Properties
● Ensure solid Earth Ground connection
● Allows for terminal landing of shielded cables
● Uses 1:0.75 audio transformer with low distortion and good frequency response
● DC decoupling, impedance of 10kΩ at 1kHz
● Allows DC wire supervision and ground fault detection of audio source
● Allows 1.00/1.55 V
rms
operation
● Harmonic Distortion: <1 %
● Crossover distortion: <1%
