Control unit (input channel 1 through 16)
(1) [TRIM] control
Adjusts the gain of each input signal. Set this control appropriately
so that the [PEAK] indicator lights at the maximum input level.
By adjusting this control appropriately, the LM16 can accept a
signal within -60dBu and -12dBu for mic input, while it can accept a
signal within -40dBu and +8dBu for line input (see page 28 for
details).

(2) [PEAK] indicator
Lights up when an input channel signal overloads.
You should set the [TRIM] control appropriately so that this
indicator does not light frequently (see page 28 for details).
(3) [LOW CUT] switch
Switches on (
) or off (
) of the low cut filter (high pass filter).
When on, the frequency range below 80 Hz is cut at -12 dB/oct.
This function is performed in the analog stage (see page 29 for
details).
(4) [LIMITER] switch
Switches on (
) or off (
) of the limiter function.
The limiter works to prevent signal clipping when the input level
exceeds the certain level. The limiter function is performed in the
analog stage (see page 29 for details).
(5) [SOURCE (INPUT/SUB IN)] switch
Available only on channels 15 and 16. It selects the channel
input source (see pages 28 and 34 for details).
When the switch is in the INPUT (
) position, a signal from the
[INPUT] connector is selected. When the switch is in the SUB IN
(
) position, a signal from the [SUB IN] jacks (L for channel 15,
R for channel 16) is selected (each press of the switch alternates
the input source). The input signal from the [SUB IN] L (or R)
jack is level-adjusted using the [SUB IN] control and sent to the
channel fader 15 (or 16) via the EQ section.
(6) [EQ HI/MID/LO] controls
These controls control gain for each EQ band (high, middle, and
low) , as well as the middle frequency.
When you set the gain control at the center position, no boost or cut
is applied (see page 29 for details).
The following table shows the EQ type, center (or cut-off) frequency
and boost/cut range of each EQ band.
When you set the [SOURCE] switch on each of chan-
nels 15 and 16 to "SUB IN" (
), the [TRIM] control is not
effective.
