Interference
If this unit is placed very near a television, picture disturbance
or noise may occur on the TV. In such a case, move the RMDS-1
preamp/processor as far as possible from the television. If the problem
persists, re-route the TV antenna cable so that it is as far as possible
from the power cable and audio and video connection cables of the
RMDS-1 system. Since the phenomenon is most likely to occur when
using a TV antenna with a 300-ohm feeder wire, we recommend using
an outdoor antenna connected via a 75-ohm coaxial cable.
Safe Limits of Operation
The RM Digital Solution system was made with the highest quality
materials for years of trouble-free performance. However, damage to
the system can occur if the system is played at excessive listening
levels. When the sound becomes harsh or distorted, you have reached
the safe limit of operation. Turn down the volume until the sound is
clear and undistorted.
Protection Circuits
The RMDS-1 amplifier features several circuits to protect the
amplifier and speakers from damage from overheating, shorts, and
other electrical faults. If these protection circuits are tripped, all
channels will turn off, even if the fault occurs on only one channel.
In such cases, turn off the RMDS-1 preamp/processor, remove the
fault (usually a short on one of the speaker wires where the + and -
wires have touched each other) and turn the system back on again.
In the case of overheating, allow the system to cool down for about
15 minutes and re-start the system. Overheating is usually a sign that
the amplifier (in the subwoofer enclosure) does not have enough air
circulation. Move the subwoofer to a less enclosed space.
Maintaining the Appearance of Your System
The preamp/processor and speaker enclosures may be cleaned with a
soft damp cloth or duster. Do not use harsh detergents and cleaning
fluids, they can permanently damage the finish. Vacuum the speaker
grilles to remove dust.
Q. “Why does my system hum?”
A. “It doesn’t know the words.”
This is what passes for humor in the audio business.
Here is the real answer.
In some installations you may hear a humming noise from the
subwoofer. Most hum problems are caused by ground loops. That is, the
electrical grounds of the components in your system are not at the
same electrical potential. To help avoid hum problems, make sure that
every component in the audio/video system is plugged in to the same
electrical circuit (not necessarily the same outlet). A common ground
loop source is cable TV. Disconnect the coaxial cable from your TV
and/or VCR. If the hum goes away, the cable TV is the ground loop
villain. In that case, you need a 75-ohm ground loop isolator. This
device is about the size of a pen and is attached to your coaxial cable
where it plugs into your VCR (or television). You can obtain this device
from some audio dealers, Radio Shack stores, Xantech (1-800-843-
5465) or Channel Plus (1-800-999-5225).
Ground loops and hum can also be the result of faulty electrical wiring
in your home. Consult a licensed electrician to evaluate and, if
necessary, repair the AC wiring in your home. Light dimmers also tend
to introduce noise into audio systems. Remove them.
