INSTALLATION

Please place the amplifier in a level. DRY place
away trom direct sunlight. We recommend that
the amp not be placed on a thick pile carpet. it
you locate them near your speakers, as this will
block the cooling vents in the amp bottom.
There are accessory amplifier stands available
to ensure good cooling. It is possible to install
this amplifier out of sight as it is equipped with
an Auto On Sensing Circuit and will turn on
when a signal from the preamp is sensed.

Do not'install the amplifier where it will become
wet as this will damage the circuitry. Please do
not sit anything on top of the RMB 100 as this
will block the cooling vents and could cause it to
overheat. It the RMB 100 is mounted inside a
cabinet. please be sure that the cabinet has a
large opening for cool air to circulate and cool
the amplilier.

"were are NO user serviceable parts inside the
RMB 100. Please do not open the cabinet as
this will expose you to potentially high volt-
age and a risk at shock. This could also dam-
age the circuits and possibly void your warranty.

Please retain the packing box and packing ma-
terial for RMB 100. This will make it easy to
transport if it should ever need service

Connecting RMB 100 to your stereo.

We have provided Unbalanced RCA input con-
nectors on the back panel ol the amplifier.
These are the most common connector tor conv
necting an amplifier and preamplilier. We have
also included an XLR connector to allow for
prearnpliliers with Balanced outputs. This con-
nector is especially useful it the amplifier is situ-
ated a long distance from the preamplifier (10-

20 Meters) and Balanced cable is inherently less
likely to pick up external noise tron-i outside in-
terference sources. Please set the input Selec-
tor Switch. located next to the input connectors.
to the input you choose.

There are Dual Speaker Output Terminals on
the RMB 100. These will make it easier to Bl-
ere speakers with the appropriate connec»
tions. These terminals may also be connected
to an RSS 900 Speaker Selector for use in a
mono or stereo installation. Consult your Hotel
hi fl Authorized Dealer lor advice about this.
It Bi-Wiring is chosen. we suggest the use of
matched sets at high pertorrnance speaker wire
to enhance the sound of your system.

(Speaker wire should be chosen by a careful au-
dition at home.)

Connect the RED (+) terminal(s) on the RMB 100
to the Positive or RED terminal(s) on the
speaker. Connect the BLACK (-) terminal(s)
on the HMB 100 to the Negative or BLACK
terminal(s) on your speaker.

NOTE: Minimum Combined Load (when Bi-
wiring) should not be lower than 4 ohms. Ask
your Rotel hi I] Authorized Dealer for advice it
you are in doubt about this. The RMB 100 will
work well with speakers from 4 to 16 ohm im-
pedance. Bi-wlnng will result in a Impedance
load that is halt of the rated speaker imped-
ance since the tweeter and wooter sections
will be in parallel.

(Example: An 8 ohm speaker will be equivalent
to a 4 ohm load it Bi-wired.)
