2.12 Dyloc processor
(PD 10.14 only)
When the DYLOC+DTC button (44)
is depressed, a super-fast and
intelligent digital/analog circuitry
gradually switches itself into action
(as can be seen by the correspon-
ding LED slowly becoming lit). After
a few seconds, you will notice con-
siderably more weight behind the
bass notes and an additional 'airy'
brightness for the high frequencies,
making for an overall improvement
of your PA sound.
At the same time, the sound
processor accurately analyses the
power output signal and protects
the speakers from mechanical
damage or thermal overload. The
bass response is enhanced in the
30Hz-80Hz range, so that no power
is wasted on inaudible frequencies.
At high sound levels, the frequency
corrections become progressively
withdrawn for a linear frequency
response, which can again be veri-
fied by the darkening control LED.
Disengaging the processor by
switch also works slowly, so that no
abrupt sound changes will be
noticed.

2.13 Limiter (PD 10.14 only)

The built-in limiter detects and
counteracts non-linear conditions
inside the mixer circuits, caused by
signal overload or impedance
mismatching. It protects your PA
system through a specially calcula-
ted control algorithm that has been
optimized for best acoustical beha-
vior without any loss in signal dyna-
mics. It works so great, it should be
always kept on - that's why we`ve
provided no switch to turn it off!
2.14 Speaker outputs
(PD 10.14 only)
Following the latest standard, the
PD 10.14 features Speakon SPEA-
KER OUT connectors (72). When
making connections, keep in mind
that the Speakon plugs have to be
twisted clockwise into their contact
position after insertion.
The pin layout of the Speakon jacks
uses pin '1+' for the signal (hot)
and pin '1-' for ground.
For the amount of speaker cabinets,
we advise that the total impedance
of the connected speakers should
not fall below the minimum recom-
mended value of 4 ohms per side.
Although the internal amplifiers
would work with no problems in
most cases, the built-in overheat
protection circuit may become trig-
gered after a while (depending on
the cooling air supply), shutting off
the amplifiers.

2.15 Headphones

If no PFL button is depressed
anywhere on the mixer, the stereo
PHONES output jack (55) always
carries the master signal. Activating
the PFL function with any button
on the desk automatically switches
the PHONES output to PFL and
makes the corresponding signal
audible in the phones.
The phone output level can be
adjusted with the PHONE VOLUME
control knob (56).

2.16 Standby

The STAND BY switch (57) can be
used for noise-free muting of the
left and right master output signal.
The standby mode is indicated by
the red LEDs (43) in the master LED
display. The tape input is not
affected by the standby switch, so
that you can still playback music
during show intermissions.

2.17 Power supply

The Mains input connector (70) is
located on the rear side of the
mixer. The connector has an in-
tegrated fuseholder for the power
supply fuse. If the fuse should blow,
replace it only with the same type
as specified on the back panel.
Near the power supply connector is
the POWER ON switch (69) which
turns the whole mixer on and of.

3. Monitor path

The monitor signals are 'tapped'
from the pre-fade channel signal
through the MON control knobs
(12) and mixed together to become
the monaural monitor signal. This

signal is again send to the MONITOR
SEND output jack (29) with the
MON fader (53) serving as a level
control. The MONITOR SEND jack
has line level for driving external
power amplifiers or active monitors
(e.g. Zeck MS 15/3 aktiv).
If one wants to hear the master
signal in the monitors instead of a
separate monitor mix, the L/R TO
MON button (47) provides just this.
Now a mono-mix of the master
signal appears at the monitor out-
put, defeating the channel monitor
controls.
A 3-band monitor EQ section (46)
with parametric mids allows to
adjust the monitor sound and helps
to combat feedback.
The effect signal can be gradually
added to the monitor signal with
the EFF TO MONITOR control knob
(48).
Sending a too strong monitor signal
from the channels can cause the
monitor output to distort. If the
CLIP LED (50) in the monitor section
lights up, gradually reduce the
MON controls of the channels until
the signal level stays with the SIG-
NAL LED (51). Use the MON fader
to compensate for the level loss.
The PFL switch (49) allows to send
the monitor signal to the head-
phone output.

4. Effect section

The PD 10.14 / MD 10.14 mixer is
equipped with an on-board stereo
digital effect unit with 99 highly
useful and professional-sounding
programs. Engaging the EFFECT
ON/OFF button (65) changes the
program number display from
flashing to constant and switches
on the effect. The effect level can
be controlled with the EFFECT
fader (54).
The effect signal can added be to
the headphone signal by using the
PFL switch (66).
