7. Lo Mid Control
This control is used to adjust the lo-mid frequency ("thickness")
level of the amplifier. Rotate the control clockwise to increase
the low-mid range frequency output, rotate counter-clockwise to
decrease.
8. Hi Mid Control
This control is used to adjust the hi-mid frequency ("definition") level
of the amplifier. Rotate the control clockwise to increase the hi-mid
range frequency output, rotate counter-clockwise to decrease.
9. High Control
This control is used to adjust the high frequency (treble) level of
the amplifier. Rotate the control clockwise to increase the high
frequency output, rotate counter-clockwise to decrease.
10. Reverb Control (MK50 only)
This control, found on the MK50 amp, will adjust the level of
reverberation that is added to the signal. The signal will be
completely dry when the control is turned all the way to the left
(counter-clockwise); the reverb will increase gradually as you turn
the control to the clockwise.
11. Level Control (MK50 only)
This control adjusts the final output level of the MK50 amplifier.
The Master level control is not featured on the MK15.
12. Limit LED (MK50 only)
Internal limiting circuitry has been adopted by the MK50 amplifier
to avoid excessive output signals causing damage to the unit.
The Limit LEd will light up when this circuit is activated. Typically,
the limiting circuitry may be momentarily activated during play. If,
however, the LEd remains illuminated for excessive periods, it's
advisable to reduce the appropriate level controls. The limit func-
tion is found on the MK50 only.

13. CD Input
These stereo RcA jacks are used to connect the output from a cd
player or tape deck to the amplifier. The signal received by these
jacks is combined to become a mono signal, which is sent to the
built-in power amp circuit.
14. Insert Jack (MK50 only)
This 1/4" TRS jack - found on the MK50 amp only - can be used to
connect external effects to the MK50 amplifier. This will require a
y-cable wired as so: ring = line out, tip = line in, sleeve = ground.
15. Headphones
This jack can be used to connect headphones to the MK15 and
MK50. The internal speaker is turned off when headphones are
used.
CAUTION: It is advisable that users do not use headphones for ex-
tended periods of time at extremely loud levels, as this could cause
irreversible damage to hearing.
16. On Indicator
This LED will light up when the amplifier is activated.
17. Power
This switch will turn the MK15 or MK50 on and off.

18. AC Power Connector (rear panel)
This Ac power receptacle is for a grounded Ac power cord. The
power cord should only be plugged into a grounded power outlet
that conforms to all required electrical codes. The Ac power outlet
this unit is plugged into should correspond with the voltage and
frequency requirements outlined on the rear panel of this amp.
NB. Do not attempt to defeat the ground pin of your AC cable, as this
is provided for safety reasons.
