RESONANCE CHANNEL 2 (11)
Used to fine tune speaker enclosure low frequency response by varying the damping factor of channel 2 at
low frequencies.
NOTE:
Not operational in mono mode.
PRESENCE CHANNEL 2 (12)
Used to fine tune speaker enclosure high frequency response by varying the damping factor of channel 2 at
high frequencies.
NOTE:
Not operational in mono mode.

SPEAKER OUTPUTS CHANNEL 1 (13)
Two r/4 " speaker outputs are provided. These jacks are in parallel. The impedance switch for channel 1 selects
the total impedance plugged into the channel 1 output.
NOTE:
When switch (mono/stereo) is switched to stereo use the numbers 16, 8, and 4 that are above the
channel 1 impedance switch.
When switch (mono/stereo) is switched to mono use the numbers 8, 4, and 2 that are below the channel 1
impedance switch.
SPEAKER OUTPUTS CHANNEL 2 (14)
Two '/4 fl speaker outputs are provided. These jacks are in parallel. The impedance switch for channel 2 selects
the total impedance plugged into the channel 2 output.
NOTE:
Not used for mono operation.
IMPEDANCE SELECTOR CHANNEL 1 (l5)
Used to select the impedance for the speaker cabinet bemg used.
NOTE:
4, 8, and 16 ohms are for stereo mode. 2,4, and 8 ohms are for mono mode (see mono/stereo switch).
IMPEDANCE SELECTOR CHANNEL 2 (16)
Used to select the impedance for the speaker cabinet being used. 4, 8, and 16 ohms are for stereo mode.
MONO/STEREO SWITCH (17)
Used to select mono or stereo operation of the amplifier.
NOTE:
When in mono mode, only channel 1 inputs, outputs, and controls will function. Use channel 1 im-
pedance selector, level, presence, resonance, and line out controls. Make sure BOTH standby switches are
on (both green LED's are illuminated).
When in stereo mode channel 1 and channel 2 may be operated independently.
LINE OUTPUT LEVEL CHANNEL 1 (18)
Controls the signal level at the line output jack. This control may be used as a balance control when slave
power amp/speaker systems are driven from the line output.
