18. "INPUT 1 ~ INPUT 10" Inputs
These ten balanced/unbalanced combination type jack (XLR and 6.3mm) input, Meant for
the connection of-condenser type microphone that accept 24V phantom power, dynamic
microphone (30-600ohms) or a high level sound source (e.g AM/FM tuner, cassette desk,
CD player, ect.) In case you are using , it is necessary to use the switch (20).

Note
Connecting unbalance microphones to the appliance when the phantom is switched on could
lead to severe damage on the microphones and is therefore not permissible. It is absolutely
mandatory to perform any plugging or unplugging of microphone cables with the phantom
power turned off. Also make sure that the phantom power is turned off when utilizing microphones
that are not meant to be operated with phantom power, The voltage that is present on pin2
and pin3 of the XLR-connector could lead to severe damages on the microphones. When in
doubt, contact your dealer before you perform any connections.
19. "INPUT 1 ~ INPUT 10" Inputs sensitivity and XLR phantom 24V switch
By turning this switches onto the "LINE" position the input can be connected to an audio source
with high level signal output. By turning these switches onto the "MIC" position, the input can be
connected to a dynamic microphone with low impedance. By turning these switch onto "24V"
position, connects the 24V phantom supply on XLR of pin2 and pin3 of inputs, necessary to
operate condenser type microphone which require this type of external supply. It is recommended
to use this switch with the general volume set on minimum.

20. Input sensitivity switch (AUX1 , AUX2)
By turning switch onto the "1" position, the "AUX 1" , "AUX 2" input suitable for connected to CD
player signal output. By turning this switch onto the "2" position, the "AUX1","AUX2" input suitable
for connected to AM/FM radio signal output. By turning this switch onto the"3" position, the "AUX1"
"AUX2" input suitable for connected to desktop cassette player signal output. By turning this switch
onto the "4" position, the "AUX1", "AUX2" input suitable for connected to high-leven signal
output.
21. TEL. Paging input level control
This control let you set the volume of the sound source that is connected to the "Tel. Paging" (23)
turning control clockwise can increase the volume of the corresponding source. We recommend
to leave the control at it's minimum setting "0" when it is not used.
23. Input "TEL.Paging"
It lets you connect to an auxiliary signal (600 ohms). The input features the "Voice Priority" function
, which overrides all other input signals, once an auxiliary message is sent. If you want to have this
function disabled forever, please contact an EV SERVICE CENTER.
24. "Priority" terminal
When short-circuiting these terminals (i.e means of using an electrical switch). The audio signals
coming form "AUX1", "AUX2","CASSETTE" and "TUNER" are attenuate, while the signals
coming form "IN1" , "IN2" and "IN4" are gaining priority.
25. Output terminal for auxiliary loudspeaker
The terminal is meant for the connection of a small external loudspeaker that gets driven by an internal
auxiliary power amplifier, providing a nominal output 1 watt. Only the mixed audio signal coming from
"AUX1" , "AUX2" "CASSETTE" and "TUNER" are included in the output signal. In addition, the
output signal is controlled only by the volume controls of the "AUX1","AUX2","TUNTER" and music
signal level control(4). This function is toggle switch the "MONITOR OUTPUT"(4) additional loudspeaker.
26. DC switch
This switch lets you turn the battery supply on or off.
