18 .
Exposure to extremely high noise levels may cause permanent hearing
loss. Individuals vary considerably in susceptibility to noise-induced hearing loss,
but nearly everyone will lose some hearing if exposed to sufficiently intense
noise for a period of time. The U.S. Government’s Occupational Safety and
Health Administration (OSHA) has specified the permissible noise level exposures
shown in the following chart.
According to OSHA, any exposure in excess of these permissible limits could
result in some hearing loss. To ensure against potentially dangerous exposure to
high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels use hearing protectors
while the equipment is in operation. Ear plugs or protectors in the ear canals or
over the ears must be worn when operating the equipment in order to prevent a
permanent hearing loss if exposure is in excess of the limits set forth here.

conditions. We’ve applied these experiences to
the mechanical design of the 24•4-VLZ PRO
and 32•4-VLZ PRO mixers.
Live sound only? No way! Although both
mixers are aimed primarily at sound reinforcement, they have features such as 4-bus,
metering and control room circuitry, that make
them serve easily as recording or mixing consoles.

ABOUT THIS MANUAL
The stuff you MUST read:
First, you must read and follow all the safety
instructions on page 2.
Before you get to work, please read the
“Quick Start” section on page 6. It’s a list of
steps that will familiarize you with the mixer
and help you set up a basic performance. The
rest of the manual explains the mixer’s features in excruciating detail.
24•4-VLZ PRO and 32•4-VLZ PRO
This manual covers both mixers. The 32•4VLZ PRO has eight more mic/line channel
strips, otherwise the two models are identical.
About all those numbers:
Every feature on the mixer has a number assigned to it. Whenever a feature is illustrated
described or mentioned, its number will be
right next to it. They’ll help you find your way
around this whopping opus, and we opus you
will like it.
Every feature of the mixer is described “geographically;” in other words, in order of where
it is physically placed on the mixer’s top or rear
panel. These descriptions are divided into
three chapters, just as your mixer is organized
into three distinct zones:
PATCHBAY (page 14)
Along the back where everything plugs in.
CHANNEL STRIPS (page 19)
The mono mic/line channel strips and the
two stereo line channel strips.
MASTER SECTION (page 22)
The section on the right.
Further information:
This icon marks information that is critically
important or unique to your
mixer. For your own good,
read and remember them.
This icon will lead you
to in-depth explanations of
features and practical tips.
While not mandatory, they
usually have some valuable
nuggets of information.
This entire manual is condensed onto one
page, albeit in hieroglyphics: see the Block Diagram on page 28.
Please come on by and visit our website, at
http://www.mackie.com. It contains helpful
stuff about mixers and audio, as well as specific information about this and other Mackie
products.

MAKE THE CONNECTIONS:
1. Make sure your amplifiers are turned off
before making any connections.
2. Connect speakers to your amplifier’s
outputs (unless, of course, you have
powered speakers, such as the Mackie
SRM 450 active monitors).
3. Plug all the sound system components into
suitable AC outlets; properly grounded and
capable of delivering adequate current. Use
power strips to minimize ground loops.
4. Using TRS or XLR cables, make connections from the mixer’s MAIN OUTS (12),
(16) to your amplification system’s line
inputs.
5. Make connections from your microphones
and instruments to the mixer: Connect
balanced microphones to the mono
channel MIC (1) jacks. (For condenser
microphones, engage the PHANTOM (19)
switch.) Connect line-level instruments
(synthesizers, guitar effects devices, direct
boxes) to the mono or stereo channel LINE
IN (2) (4) TRS jacks.
6. Follow the procedure shown on page 6 to
zero the console. This will also MUTE (38)
each channel.
7. Turn on all the AC power switches, including the mixer and all other equipment.
Leave the amplifier’s power switch for last.
This prevents power-up thumps which can
damage speakers.
8. Turn up the MAIN MIX FADER (72) to the
“U” label. You should hear nothing at this
point.
SET THE LEVELS:
1. Choose one of the microphones or instruments you’ve connected. Make some noise.
If it’s a microphone, speak at your normal
singing volume. If it’s a synthesizer, play it
at its normal output level.
2. While making noise, engage that channel’s
SOLO (39) switch.
3. Turn up that channel’s TRIM (25) up until
the METERS (54) peak near the “0” label.
4. Disengage that channel’s MUTE (38).
5. Turn up the CHANNEL FADER (42) to the
unity gain (“U” label). You should now be
hearing your noise in the phones or control
room (70).
6. If necessary, apply channel EQ (28-34)
changes. Resultant level changes can be
corrected by readjusting the TRIM (25).
7. Disengage that channel’s SOLO (39)
switch.
8. Repeat steps 1 through 7 for the remaining
active channels.
9. Stop making noise, start making music.
TWEAK THE MIX:
1. Engage MUTE (38) on all channels except
your rhythm section (drums & bass).
2. Adjust the rhythm section’s channel PANs
(37) and CHANNEL FADERs (42) to get a
good balance of levels.
3. Un-mute the other active channels and
adjust their pans and faders.
4. Tweak the fader, pan and EQ controls. Fine
tune your mix. Walk the room to see how it
sounds away from the mixer. Keep tweaking.
5. Consider applying the proper EQ adjustments by cutting certain frequencies,
rather than boosting. Compensate for EQ
cut by a slight boost in volume. For live
sound applications, this technique allows
for more gain before feedback, and gives
improved system reliability.
KNOW THESE THINGS:
• Never listen to loud
music for prolonged
periods. See the safety
instructions on page 2.
• Never plug amplifier
outputs into anything except speakers.
• Never use guitar cables to connect amplifiers to speakers.
• Before making connections to an amp or
reconfiguring an amp’s routing, turn the
amp’s power off, make the changes and
then turn the power back on.
• When you shut down your equipment, turn
off all the amplifiers first. When powering
up, turn on the amplifiers last. This
prevents power-up and power-down
thumps which can damage speakers.
• Save the shipping box and packing material. You may need them someday.

The mono channels are equipped with
Mackie’s cutting-edge XDR
preamplifiers; providing up to 60dB of rugged,
low-noise, crystal-clear, phantom-powered amplification. Their balanced circuitry rejects all
manner of extraneous interference. Professional condenser, dynamic and ribbon mics will
all sound excellent through these XLR inputs.
The inputs will accept almost any kind of
balanced mic that has a standard XLR-type
male mic connector.

Parallel Device
With nothing plugged into this jack, the
channel’s signal goes straight through the mic/
line preamp to the channel strip. With an external effects device plugged into this jack, the
channel’s signal leaves the mixer, goes through
the effects device and back into the channel
strip.
Use these jacks to send the channel signal
through a compressor, graphic equalizer or
similar device. Since the insert is before the
CHANNEL FADER (42), moving that fader will
not alter the level sent to a compressor,
thereby preserving the original signal’s characteristics.
These unbalanced jacks are wired thusly:
Tip = Send (to effects device input)
Ring = Return (from effects device output)
Sleeve = Common ground (connect shield
to all three sleeves)
EFFECTS: SERIAL OR PARALLEL?
Effects devices are used
either in serial or in parallel:
Serial means that the entire signal is routed through
the effects device. Examples
include: preamps, compres-
sor/limiters, graphic equalizers. Connections
are typically made via the channel insert jacks.
Parallel means that a portion of the signal
is tapped off to the effects device processed
and returned, to be mixed with the original
“dry” signals. Multiple signals (via multiple
mixer channels) can all make use of the same
parallel effects device. Examples include:
reverb, delay, chorus. Connections are typically
made via aux sends & aux returns.

pre EQ.
Here are three ways to use the INSERT

4. STEREO LINE IN
These balanced inputs are designed for TRS
balanced or TS unbalanced signals, from -20dB
to +20dB. They can accept any line-level instrument, effects device or tape player.
When connecting a stereo device (two
cords), use the LEFT (MONO) input and the
RIGHT input.
When connecting a mono device (just one
cord), always use the LEFT (MONO) input and
plug nothing into the RIGHT input. A trick
called “jack normalling” will cause the signal to
appear on both sides.
These inputs accept 1/4” TRS balanced and
1/4” TS unbalanced plugs, see the previous
page for wiring details.

5. TAPE OUT
Use these stereo jacks to capture the entire
performance to tape. The signal at these jacks
is the main mix, post-MAIN INSERTS (13) and
post-MAIN MIX FADER (72). Signals at these
jacks will depend on the levels set by the main
mix fader.
RCA unbalanced wiring:
Tip = hot, sleeve = shield
6. TAPE IN
Patch the outputs of an intermission entertainment device here. Any line level mono or
stereo device can be used: tape, CD player,
television audio, etc. See TAPE RETURN TO
PHONES/C-R (69) and TAPE RETURN TO
MAIN MIX (71) for more information.
When connecting a mono device (just one
cord), use a “Y-splitter” RCA adapter. It turns a
mono cord into two cords; so both the left and
right tape input jacks can be patched. This
adapter is widely available.
7. SUB INSERTS
With nothing plugged into these jacks, the
subgroup mix goes straight through the SUBGROUP FADER (60) to the SUB OUTS (8).
With an effects device plugged into these jacks,
the subgroup mix leaves the mixer, goes
through the effects device and back into the
mixer’s subgroup faders.
Use these jacks to send a subgroup mix
through a compressor, graphic equalizer or
similar device. Since the insert is before the
subgroup faders, moving the fader will not

8. SUB OUTS
In live sound applications, these jacks can
be patched into secondary amplifiers, allowing
levels to be controlled, independently of the
main mix, via the SUBGROUP FADERs (60).
Alternatively, the MAIN OUTS (12) (16)
could feed the amplifiers while the subgroups
feed a recorder.
In studio applications, these outputs can be
used as four separate paths to feed four or
more tracks of a multi-track recorder.
See 1-2 & 3-4 (40) and L/R ASSIGN (59) for
more information.
Accepts 1/4” TRS balanced or 1/4” TS unbalanced plugs, see page 14 for wiring details.
DOUBLE BUSING
Although this is a “four-bus mixer,” meaning
there are four separate subgroups available, it
can be used to feed all eight tracks of a multitrack recorder, thanks to a trick called Double
Busing.
SUB OUTS 1 and 5 carry the same signal,
and so do 2 and 6, 3 and 7, 4 and 8. Patch these
outputs into the corresponding inputs of your
multi-track recorder.
To record onto track 1, for example, put
track 1 in record mode, but leave track 5 in
safe mode. To record onto track 5, put track 5
in record and put track 1 in safe mode.

Page 17
9. STEREO AUX RETURNS
Patch the outputs of external parallel effects devices (reverb, delay, etc.) to these
inputs.
When connecting a mono device (just one
cord), always use the LEFT (MONO) input and
plug nothing into the RIGHT input. A trick
called “jack normalling” will cause the signal to
appear on both sides.
Accepts 1/4” TRS balanced or 1/4” TS unbalanced plugs, see page 14 for wiring details.
10. AUX SENDS
With aux sends in “pre” mode, patch these
jacks into stage monitor amplifier inputs. With
aux sends in “post” mode, patch these jacks
into the inputs of an effects device. See AUX
(26) and PRE (27) for more information.
Accepts 1/4” TRS balanced or 1/4” TS unbalanced plugs, see page 14 for wiring details.
11. CONTROL ROOM OUT
These line-level jacks are used to feed amplifier inputs in a control room situation,
typically found in a recording studio.
The stereo signal at these jacks is the same
as the MAIN OUTS (12) (16), except when any
SOLO (39) (47) (52) (57) or the TAPE RETURN TO PHONES/C-R (69) is engaged. Its
level is independently controlled by PHONES/
C-R LEVEL (70).
Accepts 1/4” TRS balanced or 1/4” TS unbalanced plugs, see page 14 for wiring details.
12. MAIN OUTS (TRS) and
16. MAIN OUT (XLR)
Available in two types, XLR and TRS, the
main output represents the end of the signal
path, just after the MAIN MIX FADER (72),
where the fully mixed stereo signal enters the
real world.
The XLR balanced outputs will add 6dB
when connected to balanced inputs, thereby elevating signal from the noise floor by that
amount.
The TRS balanced outputs offer the advantage of having no 6dB level change to deal
with, while still providing extraneous noise rejection. These accept 1/4” TRS balanced or 1/4”
TS unbalanced plugs, see page 14 for wiring
details.
13. MAIN INSERTS
With nothing plugged into these jacks, the
main mix goes straight through the MAIN MIX
FADER (72) to the MAIN OUTS (12) (16).
With an effects device plugged into these jacks,
the main mix leaves the mixer, goes through
the effects device and back into the mixer’s
main mix faders.
Use these jacks to send the main mix
through a compressor, graphic equalizer or
similar device. Since the insert is before the
main mix fader, moving the fader will not alter
the level sent to a compressor, thereby preserving the signal’s characteristics.
These unbalanced insert jacks are wired exactly the same as shown for INSERT (3) on
page 15.
14. MONO MAIN OUT
The signal sent out of this XLR jack is a sum
of the left and right signals at the MAIN OUTS
(12) (16). It can be used to feed a mono sound
system or a mono recording device. See OUTPUT LEVEL (15) for more information.
This XLR balanced output will add 6dB
when connected to a balanced input, thereby
elevating signal from the noise floor by that
amount.
Accepts XLR balanced plugs, see page 14.
15. OUTPUT LEVEL
Use this knob to independently set the level
of the MONO MAIN OUT (14). The level is also
dependent on the level set by the MAIN MIX
FADER (72). Unity gain is at 3 o’clock, and
there is 6dB additional gain available when
turned fully up.
To feed a microphone input, like that found
on a camcorder, turn this knob down to the
9:00 range. Use the device’s input meters to assure a good level.
17. TALKBACK MIC
Connect a balanced dynamic microphone to
this XLR jack to utilize the mixer’s talkback
feature (66) (67) (68). This input does not
provide phantom power, so it cannot accept
condenser microphones.
Accepts XLR balanced plugs, see page 14.

18. PHONES
The stereo signal from each of these identical outputs is a high-current version of the
signal from CONTROL ROOM OUT (11). Connect TRS headphones to either or both jacks.
The stereo signal at these jacks is the same
as the MAIN OUTS (12) (16), except when
SOLO (39) or TAPE RETURN TO PHONES/C-R
(69) is engaged. Its level is independently controlled by PHONES/C-R LEVEL (70).
TRS stereo wiring:
Tip = left, ring = right, sleeve = shield
19. PHANTOM
Engage this switch to provide phantom
power to all the MIC (1) input jacks. All of the
XLR mic inputs, except TALKBACK MIC (17),
are capable of simultaneously providing phantom power. Phantom power is required to
operate most condenser microphones (some
condenser microphones are battery-powered).
+48VDC phantom power is delivered to pins 2
and 3 of the XLR connectors.
For dynamic, ribbon or tube mics that do
not require phantom power, leave this switch
off. If both condenser and dynamic mics are
used, turn the switch on. Phantom power will
not hurt most dynamic mics. If unsure, check
the microphone’s user manual.
Caution: Turn all output levels down before
operating this switch to avoid the possibility of
a “pop” in the speakers.
Caution: Connecting an external line-level
device to an XLR input connector with the
phantom power activated could damage that
device. Use the LINE IN (2) or STEREO LINE
IN (4) jacks for connecting line-level signals.
20. POWER
The POWER switch is located on the rear
panel, adjacent to the AC RECEPTACLE (21).
Push in the top side of the switch to turn on,
this connects the mixer to main AC power. The
POWER (55) LED in the top right corner of the
console, will glow in confirmation.
To turn the mixer off, push the switch the
other way. Note: turning off the switch does not
remove all power from the mixer. To remove all
power, the power cord must be disconnected
from the power source.
21. AC RECEPTACLE
Connect the supplied AC linecord into this
IEC socket to provide AC power to the Mixer.
Plug the cord into a suitable AC outlet; properly grounded and capable of delivering
adequate current.
Replacement AC linecords are widely available at any office or computer supply store.
22. FUSE INSIDE
An AC power fuse is located in a tiny slideout compartment inside the AC RECEPTACLE
(21). It’s a good idea to carry spare fuses.
Always remove the power
cord before changing the
fuse.
Always use the correctly
rated fuse for your specific
mixer:

CHANNEL STRIP FEATURES
The channel strip is where you dress up
each channel’s audio: setting the gain, adding
EQ, riding the fader, tapping signal off to stage
monitors and effects devices. After a signal
leaves the channel strip it goes through a mix
stage and on to the master section (page 22).
The 24•4-VLZ PRO has 20 mono channels
and two stereo channels. The 32•4-VLZ PRO
has 28 mono channels and two stereo channels. All of the mono channels are identical,
and all of the stereo channels are identical. In
this chapter, both flavors are described with
the help of an illustration from the 24•4-VLZ
PRO. This shows a mono channel strip 20 and
its neighbor, the stereo strip 21/22.
25. TRIM
If you haven’t already, please read SET THE
LEVELS on page 8.
TRIM adjusts the input sensitivity of the mic
and line inputs connected to the channels,
mono or stereo. This allows signals from the
outside world to be adjusted to optimal internal operating levels.
Through a mono channel’s MIC (1) XLR input, there is 0dB of gain fully down and 60dB of
gain fully up.
Through a mono channel’s LINE IN (2)
TRS input, there is 15dB of attenuation fully
down and 45dB of gain fully up; with a “U”
(unity gain) label at about 10:00 (knob onethird up).
Through the stereo channel’s STEREO LINE
IN (4) TRS inputs, there is 20dB of attenuation
fully down and 20dB of gain fully up; with a “U”
(unity gain) label at 12:00 (knob halfway up).

EQ: (28 through 34)
The mixer has low shelving, mid
peaking and high shelving EQ. “Shelving” means that the circuitry boosts or
cuts all frequencies past the specified
frequency. For example, boosting the
LOW EQ knob boosts bass frequencies at
80Hz and below. “Peaking” means that
only a selected “hill” of frequencies surrounding a center “hilltop” frequency is
affected by the EQ control.
All EQ gain controls provide up to
15dB of boost (clockwise) or cut
(counter-clockwise). They are flat (no
boost or cut) at their center detents, effectively bypassing their circuits.
Note: EQ boost is a form of level
boost. With excessive amounts, the signal may become too hot and overload
subsequent circuitry. Should this happen, either back off the EQ gain, or
repeat the SET THE LEVELS on page 8.
The following graphs show how the
frequency response changes when the
various controls are adjusted.(The
graphs are simplified for entertainment
and enlightenment purposes only).
28. HI
This control is centered at 12kHz and
above. Boost it to add sizzle and definition to sounds with high-frequency
transients, such as cymbals. Reduce it to
attenuate sibilance or to mask tape hiss.

29. MID and 30. FREQ
The mono channels employ a semiparametric mid-sweep EQ. The gain is
set via MID (29), and then “aimed” at a
specific frequency, from 100Hz to 8kHz,
via FREQ (30).

LOW control,

not engaged.
34. LOW CUT
This switch (only on the mono channels)
cuts the bass frequencies below 75Hz at a rate
of 18dB per octave. Low Cut is also known as
High Pass (low cut dress=high pass rate).
To prevent muddy mixes, use low cut on every mono channel except those which carry
kick drum, bass guitar or other bass-intensive
sounds. Low cut can also help reduce the possibility of feedback in live situations and it helps
to conserve amplifier power.

Desirable low frequencies can be boosted
whilst undesirable lower frequency stage
rumble, mic handling clunks and P-p-pops are
attenuated.

35. THIS OL’ LED
This LED represents a bad thing: If a
channel’s OL LED lights up, its signal is too
hot, and subsequent circuitry may overload
(clip). To correct this, perform the SET THE
LEVELS procedure on page 8.
36. -20 LED
This LED represents a good thing: This LED
will flicker in time with a channel’s signal
when its level peaks at -20dB or higher. Also
known as a “signal present indicator,” it confirms an adequate signal level.
37. PAN
PAN adjusts the amount of channel signal
sent, left versus right, to the MAIN OUTS (12)
(16) and SUB OUTS (8). On mono channels,
the knob places the signal somewhere between
hard left and hard right. On stereo channels, it
works as a balance control, by attenuating one
side or the other.
With the PAN knob hard left, the signal will
feed LEFT MAIN, SUB 1 or SUB 3, depending
on the channel’s L-R (41) and 1-2 & 3-4 (40)
assignment settings.
With the PAN knob hard right, the signal
will feed RIGHT MAIN, SUB 2 or SUB 4, also
depending on the channel assignment settings.
With the PAN knob set somewhere in between, the signal will be shared across both
sides of the mix(es).
The PAN circuits employ a design called
“constant loudness.” As the knob is rotated
from left to center to right, the sound will remain at the same apparent volume. To attain
this, both sides of the signal must dip down
about 4 dB when panned center, to account for
the “doubling” of the signal.
38. MUTE
Engaging a channel’s mute switch severs its
signal from all subsequent outputs. Additionally, the adjacent MUTE/SOLO LED will glow.
Note: A muted channel can still be soloed
(set MODE (63) to PFL).
Note: The mixer’s pre-fader aux sends, typically used for stage monitors, follow this mute
switch. To effectively mute the signal sent to
the main mix without muting monitor feeds,
use that channel’s fader instead of the mute
switch.
39. SOLO
Engaging this switch isolates the associated channel’s signal and sends it
to the control room, phones and
meters. See RUDE SOLO LIGHT (61)
and MODE (63) for more information.
Note: A muted channel can still be
soloed (set MODE (63) to PFL).
40. 1-2 & 3-4
Used in conjunction with the PAN
(37) knob, these switches allow a
channel signal to be sent to the subgroups in stereo pairs. Typically, if a
channel signal is routed to the subgroups, it will not be directly assigned
to the main mix via the L-R (41)
switch.
For live sound, subgroups allow a
group of channels to be controlled by
one or two subgroup faders. For multitrack recording, subgroups can be used
to route groups of channels to specific
tracks of a multi-track recorder.
See PAN (37), L/R ASSIGN (59) and
SUBGROUP FADER (60) for more information.
41. L-R
Used in conjunction with the PAN
(37) knob, this switch allows a channel
signal to be sent directly to the stereo
main mix. Typically, an active channel
will always have this switch engaged,
unless its signal is being sent to a subgroup, via the 1-2 and 3-4 (40)
switches.
See PAN (37) and MAIN MIX
FADER (72) for more information.
42. CHANNEL FADER
The fader is the master level control
for the channel’s signal output. If the
TRIM (25) is set correctly, the fader
position will be best positioned somewhere between -20dB and 0dB (U).
If a fader is set all the way up,
thereby adding 10dB of gain, that’s a
sign that the TRIM (25) is set too low.
Conversely, if the fader is set way down,
the TRIM may be set too high.

In the master section, signals leaving the
channel strips are mixed, manipulated and
sent to the outputs in the patchbay. Additionally, there are four more stereo inputs here,
used to add effects to the main mix or other
destinations.
45. LAMP
This female BNC connector provides 12
volts on its center pin. Connect any quality
gooseneck lamp here.
AUX SEND MASTER: (46 and 47)
46. AUX SEND MASTERS
Aux send signals originate at each channel’s
AUX (26) knobs, are mixed together, sent
through these controls, and exit at the
patchbay’s AUX SENDS (10). Turned fully up,
these controls provide 15 dB of additional gain,
the center “U” label is unity gain and fully down
is off.
When an aux send is used for monitors,
these knobs can be used to raise or lower individual monitor mixes to suit the performer’s
taste. For recording work, these knobs are typically set near unity and left alone; most
adjustments are made per channel.
47. SOLO
Engaging any of these switches will isolate
the associated signal and send it to the control
room, phones and meters. See RUDE SOLO
LIGHT (61) and MODE (63) for more information.

Page 23
STEREO AUX RETURNS: (48 to 52)
48. STEREO AUX RETURNS
Having entered through the STEREO AUX
RETURNS (9) jacks, effects returns are controlled by these knobs, and typically continue
on to the MAIN MIX FADER (72). Effect returns are the “wet” signals, to be combined
with the channels’ original “dry” signals in the
main mix.
Turned fully up, these controls provide
20 dB of additional gain; the center “U” label is
unity gain and fully down is off. These knobs
are typically set near unity and left alone.
49. TO AUX SEND 1-2
These knobs work just like the channel
strip’s AUX (26) 1 and 2 knobs; but here, the
source signal is the STEREO AUX RETURNS
(9) 1 and 2. Typically, these knobs are used to
add effects to the stage monitors.
Via these knobs, aux return 1 combines its
left and right sides to feed aux send 1; stereo
aux return 2 combines to feed aux send 2.
Turned fully up, these controls provide 15 dB of
additional gain, the center “U” label is unity
gain and fully down is off.
50. ASSIGN TO SUB and 51. SUB
These switches allow stereo aux return 4 to
be sent to pairs of subgroups, instead of being
sent directly to the main mix. Engage ASSIGN
TO SUB (50) to divert aux return 4 to the subgroups; use SUB (51) to choose the subgroup
pair, 1-2 (switch up) or 3-4 (switch down).
For live sound, subgroups allow a group of
channel levels (and aux return 4) to be controlled by one or two subgroup faders. For
multi-track recording, subgroups can be used
to route groups of channels (and aux return 4)
to specific tracks of a multi-track recorder.
See L/R ASSIGN (59) and SUBGROUP
FADER (60) for more information.
52. SOLO
Engaging this switch isolates the associated
signal and sends it to the control room, phones
and meters. See RUDE SOLO LIGHT (61) and
MODE (63) for more information.
Note: In PFL mode, aux returns are not
soloed before their master level controls, but
are instead summed after the controls into a
mono signal and sent to the PFL mix.
53. TAPE RETURN
Having entered through the TAPE IN (6)
jacks, tape returns are controlled by this knob,
and then sent to TAPE RETURN TO PHONES/
C-R (69) and TAPE RETURN TO MAIN MIX
(71).
Turned fully up, this provides 20dB of additional gain, the center “U” label is unity gain
and fully down is off. This knob is typically set
near unity and left alone.
54. METERS
The mixer’s peak metering system is made
up of two columns of thirteen LEDs each, with
thresholds ranging from -40dB up to “CLIP”
(+22dBu at TRS MAIN OUTS (12), +28dBu at
the XLR MAIN OUT (16)).
The meters display the main mix, post
MAIN MIX FADER (72). However, when a
SOLO (39) (47) (52) (57) switch is engaged,
the meters will instead display the solo information.
A good mix will show the meter’s peaks
flashing anywhere between -10 and +10dB. Remember that most amplifiers clip at about
+10dB, and some recorders aren’t so forgiving
either. For best real-world results, try to keep
your peaks between “0” and “+7.”
ZERO EQUALS ZERO
You may already be familiar with “+4” and “-10”
operating levels. Basically,
what determines an operating level, besides available
headroom, is the relative
0dB VU chosen for the meters. A “+4” mixer,
with a +4dBu output signal, will actually display 0dB on its meters. A “-10” mixer, with a
-10dBV output signal, will also display 0dB.
To eliminate that confusion, Mackie’s compact mixers use a simpler method, where zero
equals zero: 0dBu (0.775V) at the output
shows as 0dB VU on the meters. If a “+4” output is desired, set the mix levels so the meters
“average” at +4dB. If a “-10” output is desired,
set the mix levels so the meters “average” at 10dB.
55. POWER LED
This LED glows when the POWER (20)
switch is turned on.

57. SOLO
Engaging this switch isolates the associated
signal and sends it to the control room, phones
and meters. See RUDE SOLO LIGHT (61) and
MODE (63) for more information.
Note: To solo a subgroup in AFL mode, L/R
ASSIGN (59) must be engaged.
58. PAN
When a mono subgroup signal is assigned to
the main mix via L/R ASSIGN (59), it effectively becomes another channel signal and can
be panned from left to right. This knob then
adjusts the amount of signal sent, left versus
right, to the MAIN OUTS (12) (16).
The mixer’s pan circuits employ a design
called “constant loudness.” As the knob is rotated from left to center to right, the sound will
remain at the same apparent volume. To attain
this, both sides of the signal must dip down
about 4 dB when panned center, to account for
the “doubling” of the signal.
59. L/R ASSIGN
This switch allows a subgroup signal to be
sent to the main mix. Engaging this switch will
not interrupt signal at the SUB OUTS (8) jack.
For live sound, subgroups allow a group of
channels to be controlled by one or two subgroup faders, and then sent to the main mix
using this switch and its associated PAN (58)
control.
For multi-track recording, subgroups can be
used to route groups of channels to specific
tracks of a multi-track recorder via the SUB
OUTS (8). In this case, L/R ASSIGN should not
be used.
24
Page 25
60. SUBGROUP FADERS
These faders provide 10dB of gain fully up,
unity gain at the “U” label and are effectively
muted fully down. Each fader is the master
level control for a subgroup’s signal, affecting
both the SUB OUTS (8) and the main mix, via
L/R ASSIGN (59).
SOLO: (61 through 65)
lar for studio recording applications; providing
the actual outputs of individual or multiple
channels.
64. AUX LED
Along with the RUDE SOLO LIGHT (61),
this LED blinks when any aux send master
SOLO (47) or the global aux return SOLO (52)
is engaged.
61. RUDE SOLO LIGHT
Engaging any SOLO switch (39),(47),(52)
or (57) has this result: The CONTROL ROOM
OUT (11), PHONES (18) and METERS (54),
which ordinarily receive the main mix signals,
will instead receive the solo signal. The MAIN
OUTS (12) (16) and MONO MAIN OUT (14)
are not affected by a solo condition.
Additionally, an LED associated with the
solo switch and the RUDE SOLO LIGHT will
blink obnoxiously.
The solo signal will be mono in PFL or stereo in AFL, as determined via the MODE (63)
switch. Any number of solo switches may be simultaneously engaged.
62. LEVEL
This is the master level control for all solo
signals, regardless of MODE (63). It can be set
as desired, as it only affects the CONTROL
ROOM OUT (11) and PHONES (18). It does
not affect the solo levels sent to the METERS
(54).
63. MODE
With this switch up, solo signals are PFL
(pre-fader listen). With this switch down, solo
signals are AFL (after-fader listen).
In PFL mode, the solo signal is tapped
(mono) before a circuit’s associated level control (except aux return SOLO (52)). PFL is
popular for live sound applications; providing
quick inspections of individual or multiple
channels, even if their level controls are turned
fully down.
Note: In PFL mode, when engaging a solo
switch whose associated level control is set
well below “U” (unity gain), turn down solo
LEVEL (62) to compensate for the difference.
In AFL mode, the solo signal is tapped (stereo) after a circuit’s associated controls (trim,
EQ, pan, fader, mute, etc.). It’s the equivalent
of muting all the other channels. AFL is popu-
65. SUB LED
Along with the RUDE SOLO LIGHT (61),
this LED blinks when any subgroup SOLO (57)
is engaged.
TALKBACK: (66 through 68)
66. LEVEL
Having entered through the TALKBACK
MIC (17) jacks, talkback level is controlled by
this knob, and then sent to the MAIN MIX (67)
and AUX 1-2 (68) switches. It can be set as desired by the engineer.
67. MAIN MIX
Engaging this switch sends the talkback signal to the main mix, allowing the user to speak
to the audience (live sound), or to slate a
song’s start (studio recording).
To prevent the possibility of feedback, engaging this switch will attenuate control room
output levels by 20dB.
68. AUX 1-2
Engaging this switch sends the talkback signal to aux sends 1 and 2, allowing the user to
speak to the talent, providing that they are using those aux sends for monitoring.
To prevent the possibility of feedback, engaging this switch will attenuate control room
output levels by 20dB.
69. TAPE RETURN TO PHONES/C-R
Ordinarily, the main mix (or solo) stereo
signal is sent to the control room and phones.
Engaging this switch will replace that with stereo signal from the TAPE IN (6) jacks, via the
TAPE RETURN (53) level control.
It’s typically used for studio recording, to
patch a mixdown deck’s outputs directly to the
control room and phones; thereby always listening to the mixdown deck, whether it’s in
playback or input mode.

70. PHONES/C-R LEVEL
After the MAIN MIX FADER (72), the main
mix is sent to the MAIN OUTS (12) (16) and
MONO MAIN OUT (14). It is also sent through
this control, and exits at CONTROL ROOM
OUT (11) and PHONES (18).
This knob allows engineer’s listening levels
to be set as desired without disturbing the
main mix outputs. Engaging TAPE RETURN
TO PHONES/C-R (69) or TAPE RETURN TO
MAIN MIX (71) will replace the main mix signal at the control room and phones outputs
with the TAPE IN (6) signal.
When a channel’s SOLO (39) is engaged,
the main mix signal will be replaced by the solo
signal(s), allowing the engineer to audition
channels without disturbing the main mix.
To prevent the possibility of feedback, engaging either talkback switch (67) (68) will
attenuate control room output levels by 20dB.
71. TAPE RETURN TO MAIN MIX
Ordinarily, the main mix (or solo) stereo
signals are sent to CONTROL ROOM OUT (11),
MAIN OUTS (12) (16), MONO MAIN OUT
(14), PHONES (18) and METERS (54). Engaging this switch will replace these signals
with stereo signals from the TAPE IN (6) jacks,
via the TAPE RETURN (53) level control.
Also known as a “break switch,” this switch
is useful for live sound, to play recorded entertainment between sets. It can also serve as a
global mute switch simply by patching nothing
into the TAPE IN (6) jacks.
72. MAIN MIX FADER
This fader controls the main mix levels sent
to CONTROL ROOM OUT (11), MAIN OUTS
(12) (16), MONO MAIN OUT (14), PHONES
(18) and METERS (54). The stereo main mix
can be processed before this fader by patching
an effects device into the MAIN INSERTS
(13).
The fader turned fully up provides 10 dB of
additional gain, the “U” label is unity gain and
fully down is effectively muted. Typically, this
fader is set near the “U” label and left alone,
but it can be used for song fade-outs or quick
system-wide mutes.

SERVICE INFORMATION
TROUBLESHOOTING
If you think your Mackie product has a problem, please do everything you can to confirm it
before calling for service. Doing so might save
you from the deprivation of your mixer and the
associated suffering. Here’s a few troubleshooting suggestions:
No channel signal
• Is the 1-2 & 3-4 (40) or L-R (41) switch set
correctly?
• Is the CHANNEL FADER (42) turned up?
• Try soloing that channel. Does it appear on
the METERS (54)?
• On mono channels, try unplugging any
INSERT (3) effects devices.
• Try the same signal in another channel, set
up exactly like the suspect channel.
No Output
• Are the L/R ASSIGN (59) switches set
correctly?
• Are the MAIN MIX FADER (72) or SUB-
GROUP FADERs (60) turned up?
• Try unplugging any insert (7) (13) effects
devices.
• If it’s one of the MAIN OUTS (12) (16), try
unplugging the other. For example, if it’s
the MAIN OUTS (TRS) (12), unplug the
associated MAIN OUT (XLR) (16) output.
If the problem goes away, it’s not the mixer.
• If it’s one bad side of a stereo pair, try switch-
ing them around. For example, if a left output
is presumed dead, switch the left and right
cords, at the mixer end. If the problem stays
on the left side, it’s not the mixer.
Noise
• Turn the CHANNEL FADERs (42) and
STEREO AUX RETURNS (48) down, one
by one. If the sound disappears, it’s either
that channel or whatever is plugged into it,
so unplug whatever that is. If the noise
disappears, it’s from your whatever.
Power
• Our favorite question: Is the POWER (20)
switch on?
• Turn off the power from the wall, unplug
the power cord and check the fuse (22).

REPAIR
Service for the 24•4-VLZ PRO and the
32•4-VLZ PRO is available at our factory, located in sunny Woodinville, Washington.
Service for Mackie mixers living outside the
United States can be obtained through local
dealers or distributors.
If your mixer needs service, follow these
instructions:
1. Review the preceding troubleshooting
suggestions. Please.
2. Call Tech Support at 1-800-898-3211, 7 am
to 5 pm PST, to explain the problem and
request an RA (Return Authorization)
number. Have your mixer’s serial number
ready.
You must have an RA number before you
can obtain service at the factory.
3. Keep this owner’s manual. We don’t need it
to repair the mixer.
4. Very Important: Move all Faders to their
UP position as this will help prevent
damage to the faders during shipping.
5. Pack the mixer in its original package,
including endcaps and box. This is very
important. When you call for the RA
number, please let Tech Support know if
you need new packaging. Mackie is not
responsible for any damage that occurs
due to non-factory packaging.
6. Include a legible note stating your name,
shipping address (no P.O. boxes), daytime
phone number, RA number, and a detailed
description of the problem, including how
we can duplicate it.
7. Write the RA number in
top of the box.
8. Ship the mixer to us. We suggest insurance
for all forms of cartage. Ship to this
address:
MACKIE
SERVICE DEPARTMENT
16220 Wood-Red Rd. NE
Woodinville, WA 98072
9. Ask Tech Support for the latest turn-
around times when you call for your RA
number. We normally send everything back
prepaid using three-day shipping. However,
if you rush your mixer to us by next day air,
we’ll treat it in kind by shipping it back the
same way in which it was received. This
paragraph does not necessarily apply to
non-warranty service.

SR24•4/SR32•4 LIMITED WARRANTY
Please keep your sales receipt in a safe place.
A. LOUD Technologies warrants all materials, workmanship and proper operation of this product for a

may, at their option, require proof of the original date
of purchase in the form of a dated copy of the original
dealer’s invoice or sales receipt. Final determination
of warranty coverage lies solely with LOUD Technologies or its Authorized Service Centers.
G. Any Mackie product deemed eligible for repair or
replacement under the terms of this warranty will be
repaired or replaced within thirty days of receipt by
LOUD Technologies. LOUD Technologies may use
refurbished parts for repair or replacement of any

responsibility for the quality or timeliness of repairs
performed by Authorized Mackie Service Centers.
I. This warranty is extended to the original purchaser
and to anyone who may subsequently purchase this
product within the applicable warranty period. A copy
of the original sales receipt is required to obtain
warranty repairs.
J. This is your sole warranty. LOUD Technologies does
not authorize any third party, including any dealer or
sales representative, to assume any liability on behalf of
LOUD Technologies or to make any warranty for
LOUD Technologies Inc..
