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

1

 

signal within -40dBu and +8dBu for line input (see page 28 for

 

 

 

 

details).

<Note>: When you set the [SOURCE] switch on each of chan-

4

 

 

nels 15 and 16 to "SUB IN" (

 

 

 

 

), the [TRIM] control is not

 

 

 

 

 

 

 

 

effective.

(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

 

 

 

 

 

 

 

 

 

 

 

8

 

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

13

 

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

 

 

 

 

 

 

 

 

 

 

 

14

 

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

15

 

and boost/cut range of each EQ band.
