Schematic diagram:
System operation is strait forward. You can connect your headset
,
to any of
the bases. Microphone signal from the preamp out of the base #2 is directed to the preamp
input in base#1. Channel Mic A,B,C and D
on/off switches from base#2 corresponds
now to channels E, F, G and H respectively. Listening from the eight channels are
controlled by local volume
and listen level controls
as depicted in this manual, A, B,
C and D on base#1 and E, F, G and H on base#2.
Call signalling
, remote mic kill
and buzzer kill
are to be controlled on each
base independently.
Program input signal must be splitted to each base if needed.
PA outputs from the two bases must be combined externally by using an audio mixer
and then connected to the PA system.
These audio links allows advanced functionalities:
Mic link-Direct microphone out, Mic input from external equipment, etc.
EAR link-Listen connection to external powered speakers, cue input to the operator,
etc.
GENERAL PURPOSE INPUT / OUTPUT CONNECTIONS (GPIO)
EF-202/EF-204 base station, have two general purpose inputs and two general purpose
outputs allowing remote control from/to auxiliary equipment to/from the base station.
These GPIO´s employs standard connectors (3.5 pitch) Phoenix ™ type .
The inputs are logical, with an internal pull-up of 5 Volts and 100 K
Ω
, and therefore the
simplest assembly is a simple switch to ground. Assemblies can also be connected to an
open collector output.
