Mackie M800 Manuale Utente

9. In

STEREO and MONO, connect speaker

cables to the

SPEAKER OUTPUTS

either binding post or 1/4" TS:

• The binding posts are wired
red = positive (+) and black = negative (–)

• The 1/4" TS connectors are wired
tip = positive (+) and sleeve = negative (–)

10. In

BRIDGE mode, using a single speaker:

• The speaker positive (+) connects to

CH 1’s red binding post.

• The speaker negative (–) connects to
CH 2’s red binding post.
• Plug nothing into the black posts or the
1/4" speaker output jacks.

11. Plug the amp’s power cord into the IEC

receptacle

and the other end into a

3-prong AC outlet capable of delivering at
least 12 amps (US model).

12. Make sure the signal source feeding the

M•800’s inputs is powered up and deliver-
ing signals to the amp.

13. Turn the M•800’s

POWER

switch on

and verify that the

NORM

Channel

Status LED is on.

14. Slowly turn both

GAIN

controls up:

You should now hear the lovely music.

15. If the topmost LEDs (named

OL, for

OverLoad) are flashing, turn down either
the

GAIN controls on the amp or the source

signal’s level controls (e.g., master faders).
The point is: The

OL LEDs should not light

continuously in normal use.

16. For quieter listening, it is preferable to

adjust the amp’s

GAIN

controls rather

than the source signal’s output level
(unless you have the source’s control all
the way up!)

Things to Remember:
• Never connect the
amplifier speaker outputs

into anything except
speakers (unless you have

an outboard box specifi-

cally designed to handle speaker-level
signals).

•

Read and follow all the safety informa-
tion shown on page 2 before using the
amplifier.

•

Turn the amplifier off before making any
connections, reconfiguring cables or
setting the rear panel switches.

•

When you shut down your sound system,
turn off the amplifiers first.

•

When powering up your system, turn on
the amplifiers last.

•

Keep the load above 2 ohms for stereo
and 4 ohms for bridge operation.

•

Keep the

LIMITER

ON for most

appliciations.

•

Make sure the

OL lights do not come on

very often. Turn down the amplifier or
mixer/preamp gain if they do. Failure to
do this may lead to the amplifier over-
heating, speaker distortion and damage.

•

Save the shipping boxes! You may need
them someday, and you probably don’t
want to have to pay for them again.
