CAUTION!
Never place drinks on top of the amplifier for obvious reasons. Liquids can cause
the glass envelopes of the hot vacuum tubes to crack possibly shorting out the amplifier.
Liquids can also cause damage to switches and potentiometers and generally reduce the
reliability of your amplifier as welt as require an expensive repair. If
an accidental spill
does occur, remove the amplifier from the cabinet, remove the tubes, and thoroughly
clean and dry the chassis before attempting to use the amplifier.
Be mindful not to restrict airflow to the back of the amplifier!
Never replace the protective fuse with one of a higher amperage rating. If
an
amplifier starts blowing fuses, it may be a warning of an impending problem with the
amp and should be looked over by a professional.
USE IN OTHER COUNTRIES:
Your MATCHLESS amplifier is equipped with a multiple primary winding
enabling the user to set the amplifier for various voltages and line frequencies available
in foreign countries. This is an internal connection change and should be done by a
qualified technician. MATCHLESS amplifiers can operate on voltages ranging form
110-120 volts A.C. at 60 Hertz and 220-240 volts A.C. at 50 Hertz.
If
you have any
questions about this conversion, please contact the factory.
OPTIONS:
MATCHLESS offers an effects loop option for most amplifier models. An effects
loop enables the user to insert any desired effects device between the channel
preamplifier and the power amplifier. MATCHLESS amplifiers provide two independent
loops, one for channel one and one for channel two. The effects loop jacks are located on
the rear panel
of
the amplifier. The upper jack is for the "ToneBoost" channel, while the
lower jack is for the "Pentode" channel. Each jack is configured in a
Ring, Tip, Sleeve
manner similar to a recording studio console
insert
point. Each jack
is of
the
normalizing type and contains the
send
and return information on a single 1/4" stereo
phone jack. The Tip is used for the send signal and the
Ring
is used for the return signal.
The
Sleeve
is ground. The SEND signal is derived just after the channel volume control
and the RETURN signal is inserted at the phase inverter,
just before
the Master volume
control.
A stereo "Y-cord" is required for loop operation. When the loop is not being used,
the signal is "normalized " through the jack.
The effects loop option is intended for use with guitar type foot pedals and
semi-pro
level
rack type effects. It is not designed to drive effects units requiring high
level signals (+4), as encountered in a professional recording studio.
