@ POWER
Controls power to the SF-700 unit.
@ LEVEL LOW
Controls the low-channel output level. Turning it clock-
wise
will increase the level, and turning it counterclock-
wise will decrease the level.

NOTE:
If both
LOW-MID

Controls the high-channel
output level. The use of this
switch is essentially the same as that of LEVEL LOW.
@ SLOPE
Selects the crossover cut-off characteristics of the SF-700
outputs.
Each SLOPE
switch can select either 6 dB/oct.,
12 dB/oct. and 18 dB/oct. cut-off characteristics.
