<Memo>: It is important to set the [TRIM] con-
trol appropriately. Otherwise, the signal may
be distorted or noisy.
The [TRIM] control adjust the head amp gain
of each input signal. To get the optimum gain,
set this control appropriately so that the
[PEAK] indicator lights at the maximum in-
put level.
By adjusting this control appropriately, the
LR16 can accept a signal within -60dBu and
-12dBu for an XLR connector is connected,
while it can accept a signal within -40dBu and
+8dBu when a phone plug is connected.
• Connecting sources to the input connectors
• Phantom power supply setting
<Memo>: When the [PHANTOM] switch is set
to ON, the corresponding [PHANTOM] indi-
cator on the control panel is illuminated.
<Note>:
When you turn on the phantom
power, make sure that the [TRIM] controls
on the corresponding mixer channels are set
fully left (minimum) or the LR16 is powered
off.
Usually phantom power does not damage a
dynamic microphone, however, do not con-
nect an old ribbon microphone to an input
connector to which phantom power is sup-
plied.

Adjusting the input level
<Note>:
The [TRIM] control the gain of the
head amplifier with a two-stage pre-amp and
there is a point where the gain is switched
(at approx. -35 dBu for XLR input, -15 dBu
for phone input). At this point, a noise may
be generated.
• Selecting channel source
Each of mixer channels 1 through 16 provides
a combo type -- a combined XLR connector
and phone jack in one. You can connect a
microphone to the XLR connector or connect
a line signal to the phone jack. (The phone
jack can accept both balanced and unbal-
anced signals.)
You can adjust the input gain using the [TRIM]
control on each mixer channel strip.
48 V phantom power can be supplied to the
XLR input connectors. For most of condenser
microphones, the phantom power is required.
You can turn on or off phantom power using
the [PHANTOM] switches in eight channel
groups (1-8 and 9-16) using these switches.
Setting the [SOURCE] switch on each mixer
channel to "INPUT" (
) selects the channel
input signal. Setting the [SOURCE] switch to
"TRK" ( ) selects the track playback signal,
or the [SUB IN] signal or the memory play
signal when it is assigned to the channel.
