1.) Mic/Line Input Jack 1 -
this is a 1/4 2 conductor input jack for plugging in your instrument. It is
intended for keyboards or Hi-Z microphones but will accept other instruments as well.
2.) Mic/Line Input Jack 2 -
this is a 1/4 2 conductor input jack for plugging in your instrument. It is
intended for keyboards or Hi-Z microphones but will accept other instruments as well.
3.) Volume 1 -
this control is the output volume control for the Input #1. Slowly increase the control to
increase the volume. If you are using a keyboard with a preamp, set its level for a mid position before
increasing this control otherwise distortion may occur. Both inputs follow the same tone circuit as the
other input.
4.) Volume 2 -
this control is the output volume control for the Input #2. Slowly increase the control to
increase the volume. If you are using a high impedance microphone, be careful when increasing the
volume. Depending on mic position, it may feedback if mic is in front of speaker. Both inputs follow the
same tone circuit as the other input.
5.) Low -
this control is the bass control. It is active and set to boost or cut frequencies at 55 Hz. This
will effect the low frequency signals. Turning it fully clockwise, the signal is boosted 18 db. Turning it
counterclockwise, the low will be rolled off -18db. Especially good for cleaning up preset patches or
making thin patches sound fuller.
6.) Lo Mid -
this control is the Low Midrange control. It is active and set to boost or cut frequencies
at 350 Hz. This will effect the mid-low frequency signals. Turning it fully clockwise, the signal is boosted
12 db. Turning it counterclockwise, the low-mids will be rolled off -12db. Especially good for cleaning
up preset patches.
7.) Hi Mid -
this control is the High Midrange control. It is active and set to boost or cut frequencies
at 2.5KHz. This will effect the mid-high frequency signals. Turning it fully clockwise, the signal is boosted
12 db. Turning it counterclockwise, the low-mids will be rolled off -12db. Increasing this will add punch
to keyboard patches or vocal presence.
8.) High -
this is the high frequency tone control. It is active and set to boost or cut frequencies at 8KHz.
This will effect the high frequency signals. Turning it fully clockwise, the signal is boosted 18 db. Turning
it counterclockwise, the low-mids will be rolled off -18db. This will add or subtract the high end shimmer
and clarity.
9.) Reverb Level -
(only on the KMA16R). This control adds the spring reverb and mixes it into the
main signal buss. Reverberation creates a trail like effect with the sound. It lets the notes hang in the
air longer, extending the sound.
10.) Headphone Jack -
this is a 1/4 3 conductor jack for plugging headphones. It will sum the signal
and put the sound in both ears, thereby creating a pseudo-stereo sound. Volume will be determined
by the volume control on the channel you are on. It will disconnect the internal speaker when plugged
in. This will allow quiet practicing.
11.) Jewel Light -
this jewel light lets you know that the amplifier is on.
12.) Power -
this switch turns on and off the AC power to the amp.
Back Panel -
this is a 2 conductor 1/4 speaker output jack. This will disconnect the internal speaker
and allow an external speaker cabinet to be employed. Rating is 8 ohms.
