EXTERNAL EFFECTS SENDS AND RETURNS
29
➤
EFF SEND: level control for the effect send. It is the mix of the
signals sent from the EFF send volume on each channel and sets the
level of the signal appearing at the EFF SEND jack output.
30
➤
EFF RETN: level control for the effect return. Sets the signal
level of the external effect return.
31
➤
EFF TO AUX: sets the level of the external effect to be sent to
the AUX output (monitor).
32
➤
EFF BAL: stereo balance of the external effect.
Allows to adjust the level of the stereo signal of the effect in the
L and R master outputs.
●
connections:
33
➤
EFF SEND: jack output socket for the external effect send.
34
➤
EFF RETN L/R: 2 jack inputs for the external effect return.
• They can also be used as 2 extra line inputs.
■ Connect the EFF SEND output to the input of the external effect.
■ Connect the L and R outputs of the external effect to the
L and R EFF RETN inputs of the stereo effects return.
• For a mono effect connect its 'only effect' output to the 'L / mono' socket.
■ Use the EFF controls on each channel to determine the quantity
of channel's signal to be sent to the external effect, the EFF SEND
control (29) to determine the quantity of signal to be sent to the "eff
send" output, and the EFF RETN, EFF TO AUX and EFF BAL (30, 31,
32) controls to adjust the effect return level in the "aux" and master
"L/R" outputs.
• The EFF control on each channel is also the effect send for the internal effect.
To exclude the internal effect, turn it off by releasing its 'on' button.
Note : The AUX output (if not used as monitor output) can be used in place of
the EFF SEND output. In this case the signal of the external effect is adjusted by
means of the AUX send control on each channel and it is thus fully independent.

MASTER SECTION:
35
➤
L/R MASTER: volume faders for the left and right master
outputs.
36
➤
LEFT/RIGHT LEVEL: two 12 segment LED arrays give istanta-
neous reading of L and R outputs levels.
37
➤
PROCESSOR: pushing this button activates an internal
processor which has effect on the L and R master outputs allowing
to obtain a 'full-bodied' sound even with a soft sound level (very
useful when performing in clubs, small venues etc.).
In the XD13 this processor has effect only on the XLR outputs
whereas the L and R Insert sockets are not affected by it.
In the AD52 this processor affects the power outputs
38
➤
AUX MASTER: volume control for the auxiliary output.
The auxiliary master output is the mix of the individual channel's
AUX sends.
39
➤
TAPE IN VOL: sets the level of the signal at the 'Tape in'
socket of the mixer.
40
➤
PHONES VOL: level control for the phones output.
41
➤
POWER: mains power switch.
● connections:
42
➤
XD13 LEFT/RIGHT OUTPUTS: L/R master outputs for the
connection of power amplifiers or active speaker enclosures.
■ Connect the L/R master outputs to the inputs of the self-powered
speaker enclosures or to the inputs of the power amplifiers.
Adjust the volume fader on each channel as well as the L/R master
volume faders.
10
CONTROLS AND CONNECTIONS
Each output can drive up to 10 parallel connected active speaker
enclosures or power amplifiers.
Note : Using standard mono jack plugs the L/R insert sockets may be used as
normal jack outputs. In this case the XLR outputs are disconnected.
☛
see fig. 1A page 17
43
➤
AD52 L/R SPEAKER OUTPUTS: output sockets for the internal
power amplifiers. Minimum load impedance for each amplifier is 4
Ω
.
Note : Each output is fitted with 2 jack and 1 XLR sockets (parellel connected)
and features speaker protection fuses, electronic protections, delayed power-up
sequence, automatic troubleshooting and forced cooling.
☛
see fig. 1B page 18
44
➤
L/R INSERT: these stereo jack sockets (post-master faders)
allow the connection of external auxiliary equipment such as stereo
equalizer, limiter, audio processor, etc… to the master outputs.
☛
see fig. 2A page 19
In the mixer XD13 they may also be used as normal jack outputs
(using standard mono jack plugs). In this case the XLR outputs are
disconnected.
☛
see fig. 2A page 19
In the powered mixer AD52 these sockets can also be used as
preamp-outputs for connecting powered speakers or external power
amplifiers.
■
It is possible to use either the line and power outputs at the same
time (thus adding external amplification). Take out the signal from
the insert sockets by means of two stereo jack plugs, in which you
have previously joined the RING with the TIP and send it to the
inputs of the active speakers by means of mono jack plugs.
☛
see fig. 2B page 19
• If you plug mono jack into the stereo insert sockets, the power outputs are
automatically excluded.
45
➤
AUX OUT: auxiliary output (monitor). It can drive up to 10
parallel connected powered monitors.
■ Connect the AUX socket to the input of the self-powered stage
monitor. Adjust the AUX send of each channel and the AUX
MASTER volume.
☛
see fig. 3 page 19
• If it is not required as monitor output, it can be used as effect send (see fig. 4).
46
➤
L/R TAPE IN/OUT: PIN in-out sockets. They allow connection
to stereo tape recorder.
■
Connect the L/R TAPE OUT sockets to the inputs of the tape
recorder (line in) and the outputs of the tape recorder (line out) to
the L/R TAPE IN sockets of the mixer. If the TAPE IN inputs are not
used, it is suggested to keep the volume control fully closed, to keep
output noise to the minimum value.
■ For playback: switch the recorder to play and adjust the TAPE IN
VOL control on the mixer (and the output volumes of the tape
recorder, if available).
■
For recording: switch the recorder to the 'record' mode and adjust
the input volume of the tape recorder. Set the output volume
control of the tape recorder to its lowest setting. In case your tape
recorder has no output volume control, disconnect the cables from
the TAPE IN sockets. The signal sent to the tape recorder is
unaffected by the L/R master faders settings.
• The L/R Tape inputs accept any line signal. You can thus use them as 2
extra line inputs to connect instruments, expanders or the L/R outputs of a mixer.
