The main menu consists of 8 options (Input Configuration, Channel Assign, OUT / AUX
Configuration, CUE Configuration, Clock Timer Setup, System Configuration, Password
Configuration and Save/Recall Setup) - select one of these to access the typical characteristics
of that menu.
I n pu t Con figu r at ion
It is possible to set the different inputs depending on the connected sources. The first step is to
assign the name source (Ie. Line1= CD1), the second one is to enter into the setup menu where
is possible to set the other channel functions.
The inputs already setted will then be assigned to the 8 available channels (slider) by using
"Channel assign" menu.
There are three types of input: 4 microphone, 16 analog line and 4 digital line (AES/EBU).
Obviously, LINE inputs, whether analog or digital, can be of 3 different types: NORMAL,
TELCO 1 and TELCO 2.
Let's see what the Telco mode is. Th is m ode st r ict ly con cer ns an alog or digit al

PRI VATE COMMUNI CATI ON
While the DJ or the m usic are broadcast live, the director talks with the listener via the service
microphone, by pressing the TB Key. The director is able to hear the listener via the CUE line. I f
the channels being broadcast live at the tim e are program m ed to also send their signal toward the
TELCOs, the listener on the telephone, in addition to hearing the director, also hears what is being
broadcast. The system is designed so that, when the TELCO channel is in STOP state (therefore,
in private m ode), the signal directly sent by the m odules to the TELCO bus must be attenuated to
a certain preset degree, whereas the signal com ing from the service microphone m ust be set to
normal level.
DI RECT COMMUNI CATI ON
While broadcasting live, t he DJ t alks wit h t he listener ( also live) via t he DJ m icrophone. The MI C
DJ channel is in START state and t he slider is raised, t he TELCO channel is also in START st at e,

fields of the selected option, and use the up and down arrows to change the value of the data-
item under the cursor. When you have finished entering the field, press "Enter" to exit the option
you have just edited, and proceed to edit other data.
This is the procedure to arrange association of the device at input.
Exam ple: I nput Mike 1 - Guest1 Microphone
- Locate the flashing cursor in the box to the left of the Mike 1 words -
Press "Enter" - Use the up arrow key to select the letter N -
Use the right arrow key to move into the next field -
Use the same technique to fully compose the word Guest1 - remember you have a maximum of
10 fields at your disposal. - Press Enter, and the cursor will move to the left of the word
Setup referring to Mike 1.
You can proceed in the same way for all the inputs.
We shall now see how to set specific parameters for the three types of input.
M ik e Se t u p
You can set all the necessary values by using the editing system we explained previously.
Let's see to what the 26 available parameters refer.
MI C ADJ
Adjustment of input level in the range 0 ÷ +30 dB for microphones with very low levels.
LEVEL
Typical adjustment of input level in range - 12 ÷ +12 dB
PAN

INSERT
This function enables you to shift the pre-amplified microphone signal to the INSERT input/output
instead of to the analog bus. If enabled, it sends the output signal to the insert connector - this
signal can then be used as an input of an external audio processor. The processed signal is then
re-introduced to the insert input for re-distribution to the analog bus.

There are four sections referring to function keys F1, F2, F3 and F4. Similarly, there is a
Out event section, which refers to an event - e.g. arrival of an external command -
pressing of certain keys or sets of keys ,etc. In the Input Name section it is necessary
to assign a name (max 4 char) to control the input photocouplers 13, 14, 15 and 16
status (ie incoming phone call).
We shall now take a look at an example for setting F2.
Using the editing method we described previously, you select one of the 16 available

TB
When the TB key (Talkback) is pressed, the signal of the service microphone is sent to the busses
selected in the "AUX In/Out Setup" menu.
BEW ARE: the Microphone signal replaces the signal which had up to then been directed to the pre-
selected outputs. When the TB key is released, everything returns to its previous state.
PRIVATE communication, using a telephone hybrid (AEV mod. ITB302) if any, can be performed
only by using the TB microphone signal, with "TELCO" channel in STOP and CUE selected.
D ir e ct co m m a nds: H e a dse t se ct io n
The level of the Headset output can be varied with the "Headset" potentiometer on the panel.
The signal directed to the Control Room is usually sent to the
headset output. Whenever one of the CUE keys is activated, CUE replaces the Control
Room signal. There may be exceptions depending on activation of the DIM and SPLIT
functions.
DI M
If activated, it directs the signal on the CUE bus to the L and R headset output,
and adds it to the signal present on the bus selected by the Control Room
section - the latter is attenuated.
SPLI T
If activated, it directs the signal on the CUE bus [(L+R)/2] to the left ear-piece
of the headset, and directs the signal on the bus selected in the Control Room
section [(L+R)/2] to the right ear-piece.
DI M+ SPLI T
The two functions can also be combined, so that the CUE signal is on the
left ear-piece of the headset and the signal selected by the Control Room
section is on the right side, attenuated.
