4. Locate and
identify the hard-
ware that came with
your Meter Bridge:
■■a. Two (2) slotted screws;
■ ■ b. Two (2) collar pieces (Note
that there is a small
pin protruding from
the bottom of each
collar piece);
■■c. Two (2) Allen head screws;
■■d. Two (2) lockwashers;
■■e. One (1) allen wrench.
5. Remove the plastic caps that cover
the Meter Bridge mounting holes
on each side of the Console (Draw-
ing A). Feed them to your boa.
6. Align the Meter Bridge
with the Console (B) and lower it
into place. Tilt the Meter Bridge
back until it is
at rest against
the Console
chassis (or
your tangle of
patchcords).
Make sure
that the meter
bridge's
mounting
holes line up

Congratulations on adding a Meter
Bridge to your Mackie Designs 8•Bus
Console. Installation is very straightfor-
ward and should take just a few minutes.
The only reason we've included so many
step-by-step drawings is because our art
department wanted something to do on
a rainy day1.
INSTALLATION INSTRUCTIONS
1. Locate the warranty card and fill it
out. If you bought your Meter
Bridge at the same time you pur-
chased an 8•Bus series console, you
don't need to answer all the ques-
tions on the card that came with the
Meter Bridge. Just fill in the model
number of the Meter Bridge, serial
number, purchase date and dealer,
and your name and address.
2. Make sure that your 8•Bus Console
power supply is turned off.
3. Remove the Meter Bridge from its
plastic bag. Save the bag. It's handy
for wrapping boa constrictors or
moray eels before popping them in
your freezer. Also, save the box.

to do quite a nice job.

with the console's mounting
holes.
7. Hand-insert one collar
piece into each side, with
the “teeth” pointing out
(C). Occasionally, the end
caps of the Console will try
to interfere with
this step. Don't get
upset. Simply loosen the CONSOLE end
cap screws, install the collar and then re-
tighten the screws.
8. Turn the collars by hand until you feel the
pin seat itself (it will stop turning).
9. Slide one lockwasher onto each allen-head
screw.
10. Secure the collars by inserting an Allen-
head screw on each side (C). Take care not
to cross-thread the screws or strip the
screwheads. Tighten the Allen screws
securely.
11. Using a hefty screw driver, install a flush
screw almost all the way into each side
(Drawing D at right).
12. Raise the Meter Bridge as far forward as it
will go.
13. On the Console, locate the rubber plugs
that cover the Meter Bridge ribbon cable

sockets. The 32•8 has five; the 24•8 has
four; the 16•8 and MB•E each have three
(see epic MondoDrawing E at the top).
14. Remove the rubber plugs and feed them to
the afore-mentioned boa constrictor.
13. Making sure that the plug and socket are
aligned, firmly insert each ribbon cable into
its corresponding socket in the Console (F).
Take care to make sure that the cable is
not
twisted 180˚(sounds insulting to caution
you against something like this, but we've
seen it done.) Unless your fingers are
microminiature, you'll probably need to use
the eraser end of a pencil to press down on
the plug and make sure that it is fully
seated (G).
16. Slide the new improved, slotted rubber
plugs (that are pre-attached to the ribbon
cables) down until they fit snugly into the
rectangular Console holes (Drawing H).
17. Adjust the Meter Bridge to the desired
angle and tighten the screws.
18. Make yourself a sandwich. Wash hands
before returning to work.

Bridge activity on Channel 1. Whoop with
unbridled joy.
5. Repeat steps 3 and 4 for each channel of
the Console. You'll probably want to stop
whooping after about the sixth or seventh
channel.
6. Assign the last channel you tested to the
L/R MIX. Turn up the L/R MIX fader.
Engage the L/R switch in the MONITOR
section of the Console.
7. Confirm meter activity on both the Meter
Bridge VU meters and the console's L/R
MAIN LED meters. Pan the channel left and
right to confirm that all meters understand
this sort of thing.
A SHORT TEST-DRIVE
The point of this exercise is to make sure that
all the Meter Bridge channels (and all the LED's
on each channel) work properly. Better now
than later.
1. Power up your 8•Bus Console. Confirm
that the following are alight:
A. The console's power LED;
B. The meter bridge's VU meters (unless
you're installing an MB•E); and
C. Either the TAPE or CHANNEL LED on
the Meter Bridge.
If nothing lights up,
turn the power off
immediately and re-
check your connec-
tions. If all is aglow,
proceed to the next
step.
2. If the Meter
Bridge TAPE
LED is on,
press the
SOURCE
button below
it once to switch to
CHANNEL. If the
CHANNEL LED is
on, switch it to
TAPE and back to
CHANNEL, to
confirm that
the switch is
behaving.
3. Send a signal
into the main
path of
Console Channel 1. The –20 LED above
the fader will let you know if you have done
so.
4. After making
sure that the
channel is
not muted,
turn up the
channel
fader. Con-

TROUBLESHOOTING
If a group of LED ladders doesn't respond,
there's a good chance that the corresponding
ribbon cable isn't pushed in all the way. Make
sure that it is firmly plugged in.
If nothing responds, contact your dealer or
Mackie Designs Tech Support immediately.
METER BRIDGE OPERATION
Your meter bridge's ballistics and general
behavior is the same as the submaster LED
ladders on the Master section of the Console.
For the excruciating details, read the section on
METERING on page 11 of your 8•Bus manual.
When TAPE is selected on the Meter Bridge,
the channel meters will show you what is com-
ing out of your multitrack into your tape returns
—before any signal manipulation in the chan-
nel (but after the +4/–10 switching circuit). The
channel meters should behave just like your
multitrack's meters.
When CHANNEL is selected, the meters
“see”the channel's direct output post-EQ,
post-fader and post-mute. This is particularly
handy for live mixing.
The VU meters on the MB•32, MB•24 and
MB•16 “look”at the same signals as the
console's L/R LED meters. You will notice that
the VU meters and LED meters will not always
agree with each other. THIS IS NORMAL. The
LED meters read peak activity and will show
every dynamic nuance. The VU meters, de-
signed in the Early Bronze Age, are slower to
respond and therefore show an RMS or
average
signal level. This will usually be several dB less
than the peaks shown on the LED meter.
Final suggestion: Turn your overhead lights
way down so that your Mackie system will look
like the Death Star from Revenge of the Jedi.
Put baseball cards in the power supply fan to
simulate a warp drive.
Just kidding.
