Wire Gauges
Selection of the appropriate wire gauge is important to system operation. A cable
that is too light will result in amplifier power being wasted due to the series
resistance of the cable. In addition, loss of low-frequency performance may be
experienced due to degraded damping f actor. The chart below illustrates the
appropriate minimum wire gauge for various cable length and speaker
impedance combinations.
When using this chart, k eep in mind that the two 8 ohm speakers in parallel will
equal a 4 ohm load (see "Looping Speakers" below).
Additional Information
Polarity
A positive voltage applied to the tip of the NL-4 plug and plus one of the NL-4
connector will produce a forward mov ement of the speakers cone. These
conv entions should be maintained throughout the hook -up of speaker systems to
maximize performance.
Looping speakers
Running too many speakers from a single amplifier channel may result in
damage to the amplifier and/or degraded audio performance. To calculate the
combined impedance of multiple identical speak ers in parallel.

Input Panel
Loop thru capability
The two jacks on the rear panel of the MK-12A are wired in parallel. This
means whatever you plug in to either of the two jacks is av ailable to patch out of
the other jack to
another
loudspeaker.
Sonic Guard
MK-12A speakers are equipped with SonicGuard circuitry which protects
your high frequency driv er against damage from occasional ov erpowering of the
system. SonicGuard gently compresses the signal in a virtually inaudible manner
by div erting the exc ess power away from the compression driver.

SonicGuard provides protection against peak and average ov erpowering
while passing transients that contribute to the character of the music.
Note: SonicGuard circuitry incorporates light bulbs which illuminate when the
circuitry activates.
