MEITNER MTR-101 MONO
Thank you for
buying this Museatex product. Please read the following operating instructions
to ensure that you obtain the maximum enjoyment from this product.
In a typical installation,
the amplifier may be stacked above or below a preamplifier. The Meitner MTR-101
will function adequately in this type of installation. However, to optimize
the sound quality of the unit we recommend that you:
- Place the amplifier
close to the speakers and use the shortest possible length of speaker cables.
This method requires long interconnect cables between the preamplifier and
the amplifier. This may be a problem with some preamplifiers, and we recommend
that you check with the preamplifier manufacturer regarding maximum length
of interconnect cables.
- The Meitner
PA6i along Museatex Audio interconnects can be safely used for lengths of
up to 100 feet.
- Place the power
amplifier alongside the preamplifier, rather than one on top of the other.
- The MTR-101
has a custom designed transformer, and one of the design objectives of separating
preamplifiers from power amplifiers is to ensure that magnetic field interference
from the transformer to the preamplifier is kept to a minimum.
- The unit should
be allowed to "breathe". Ensure that the heat sink assembly is kept free of
obstructions with at least four inches of space behind it if placed in a closed
- Connect speaker
to the red/black binding post at the rear of the unit.
- Input of the
MTR-101 is an RCA type jack at the rear of the unit.
- Switch on the
MTR-101 by pressing "power" on front panel. Red light comes on; unit is ready
for listening. Turn up volume!
In the event of
excessively high power demands, into very low speaker impedances and over long
periods of time, the temperature of the heat sink may rise above 85 degrees
Celsius. When this happens, the light will flash very quickly, and the amplifier
will shut down. It cannot be re-started until the unit has cooled down, at which
time the light will be flashing slowly. When the slow flash begins, press "power"
once to reset; light goes out. Press "power" again to turn unit on; light comes
A "DC offset error"
protection is also incorporated into the MTR-101. "DC offset error" may occur
if speakers and/or cables are shorted, or when a faulty preamp (with excessive
offset) is plugged into the MTR-101.
The flashing sequence
for these errors is the same:
- Fast flash when
- Slow flash when
error is corrected.
- Press power
once to reset. (light goes off)
- Press power
again to turn on. (light goes on)
The MTR-101 is
designed to give you many years of use without adjustments or service. The following
suggestions should help prolong its life:
- If convenient,
leave the amplifier "on" at all times. If you are leaving the unit unattended
for several days we recommend that you switch off the unit and unplug the
- Avoid placing
the unit in direct sunlight as the wood may change colour.
- The wood sleeve
should be treated as any other fine funiture, and wiped regularly with suitable
- The front panel
should NOT be cleaned with cleaners that contain ammonia. Wiping with a damp
cloth should take care of any marks left by fingerprints, etc.
