The two master faders (49) are the
final volume control for the mixer.
If the PFL LED (39) is dark, the two-
row LED chain (38) shows the level
of the stereo master signal.

2.1 Master EQ section

34
The 5-band master EQ's (42) main
35
purpose is room-acoustic compen-
sation. For this reason the frequen-
37
cies are tuned differently from the
channel EQs. Frequency corrections
of the PA speakers should be done
extremely carefully with the master
EQ and preferably in a subtractive
manner - the Profiler has a powerful
55
amplifier! Excessive boost of treble
frequencies always increases the
danger of noise and feedback.
43
If you think your Profiler should
56
produce some more top and bottom
57
end, use the DIGITAL SOUND PRO-
CESSOR switch (see 2.10). As a rule,
the master EQ should always be ad-
58
justed before the channel EQs, pre-
59
ferably with a test CD through the
60
AUX RET jacks (23).

2.2 Insert jacks

62
64
The master INSERT LEFT/RIGHT jacks
65
(20) allow to send the master signal
52
through an external effect device
before it enters the power amplifier.
The pin layout is the same as on the
53
channel insert jacks (tip=send,
51
ring=return).
These insert jacks also allow the
54
connection of Zeck DCA 501L active
subwoofers for an active two-way
PA system. The DCA 501L's built-in
active crossover filters out the bass
frequencies for its own amplifier,
sending back only the highs to be
amplified by the mixer. Appropriate
Y-cables for this kind of setup can
be ordered from Zeck.

2.3 Amp In

Whenever you want to use the PD's
internal power amplifier for external
sources, e.g. an external mixing con-
sole,the AMP IN LEFT/RIGHT jacks
(21) are the right inputs. Inserting a
phone plug into these jacks auto-
matically disconnects the power

amplifier inputs from the rest of the
mixer. The master faders do not
work in this mode.
This input is also usable for the
mixer's own purposes: whenever
one wants to use an external power
amplifier through the Line Out out-
puts, the unemployed internal amp
can be operated as a monitor power
amplifier by running a
Y-cord from the MONITOR SEND
(27) jack to the AMP IN jacks.

2.4 Mono Out

Having a monaural signal available
is handy for driving subwoofer
speaker systems or remote back-
ground speakers. The MONO OUT
jack (26) provides a line-level
monaural master signal, mixed
together from the left and right
channel. The signal level of this out-
put is sufficient for driving external
power amplifiers and is controlled
by the MONO OUT control knob
(31). It is also affected by the
master faders.

2.5 Line Out

The Line Out jacks (22) carry the ma-
ster signal and are electronically lo-
cated between the master EQ
section and the master faders. For
this reason, the line-out level is not
affected by the master faders but
can be level-controlled by the LINE
OUT control knob (32).
