7. POWER INDICATOR.
When this yellow LED is illuminated, the foregoing informa-
tion should be correct. If darkness is present at this location, most or all of the above will
be inoperative.
6. OUTPUT LEVEL CONTROLS.
Each pair of output controls sets the individual chan-
nel output levels. The inner knob is for channel A, the outer is channel B.
5. STEREO/MONO SWITCH.
To make one of the inputs on the FPS 28 available to all
eight outputs, this switch needs to be in the MONO position. In the STEREO mode, Input
A drives bus A only; Input B connects to bus B only.
4. MASTER A AND B LEVEL CONTROLS.
These concentric controls set the level to
each of the buses. Output levels may be selected via the four pairs of controls connected to
the output sections. This is true, however, only if the internal PRE/POST switches are in
the POST position (as shipped).
In the PRE position, the Master Level Control is bypassed for that respective output
and only the Input Gain Control and the Output Level Control have any effect on an in-
dividual output.
3. PHANTOM POWER SWITCH.
In the ON position, 15VDC phantom power will be
present on both 3-pin inputs on the rear of the module.
2. A AND B OVERLOAD INDICATORS.
These red LEDs illuminate whenever the com-
bination of input level and input gain adjustment cause the input amplifiers to reach or ex-
ceed a level equal to 4dB below clipping.
1. INPUT LEVEL CONTROLS.
These concentric level controls set the level of each
input to be routed to the channel A bus and the channel B bus. The inner knob controls
the level to be sent to bus A, the outer knob controls the signal applied to bus B. Rotating
the knobs upward together from the “0” position creates a “pan centered” effect. Leaving
one off and increasing the other emulates a full pan to one bus or the other.
