PRECAUTIONS
• The MT44D functions as a standard stereo
cassette deck when loaded with any standard stereo
cassette tape. For four-channel multitrack record-
ing a special sensor foil (supplied) must be affixed
to the cassette housing window.
@ The MT44D is designed exclusively for use with
high-quality chrome-formulation cassette tape (High
Bias, 70 џ=5ес ЕО). Avoid C120 tape lengths because
the extreme thinness of the tape can result in
degraded sound quality and damage to the transport
system. |
• То ensure а high signal-to-noise ratio апа mini-
mum distortion, the MT44D has а high-quality
permalloy reproduction head. Oxide flakes from
old tape and dust or dirt can impair the perform-
ance of this head, so it should be cleaned regularly
with cotton buds and a tape head cleaning fluid, or
a head cleaning tape. The pinch roller should also
be cleaned at the same time.
Ф Locate the MT44D out of the direct rays of the
sun, also avoiding locatians subject to vibration,
excessive dust, heat, cold or moisture.
ө Irreparable damage may result from opening
the MT44D cabinet or attempting to alter the
internal circuitry.
@ Avoid dropping your MT44D or subjecting it
to any kind of shock, as impaired performance
may result.
• Do not attempt to clean any part of the MT44D
with chemical solvents (such as alcohol or benzine).
Wipe clean with a soft, dry cloth.
® The 50/60, Hz line frequency selector on the rear
