AUX 1 SEND
The MDR16 has two auxiliary sends which can be used for sending signals to the
external effects devices or for creating a monitor mix. The AUX1 section is often used
for a monitor mix in a live sound application, or for a headphone mix in a recording
application. Each input channel includes an AUX 1 send which controls the amount of
that channel's signal that is sent to the AUX 1 bus. The Input channels' AUX 1 sends are
mixed together and are sent to the AUX 1 OUT jack.

AUX 1 PRE/POST switch
On channels 1 through 8, it is possible to set the Aux 1 control knob to send signal
from before (PRE) or after (POST) the channel fader. Following is a description of the
signal paths.
PRE FADER AUX send - If you want to use AUX 1 as a send for a monitor, set the PRE/POST switch to the up or PRE
position. When AUX 1 is set to "PRE", the channel's signal will be sent directly to the AUX1 output using the chan-
nel AUX 1 control knob. In this mode the channel fader has no effect on the signal being sent from the AUX1 knob.
So in a stage monitor situation, only the Aux 1 knob, and not the channel fader, controls the level sent to the AUX1
output, and therefore, the overall volume of that channel in the monitors.
POST FADER AUX send - If you want to use AUX 1 as a send to an effects processor, set the PRE/POST switch to the
down or POST position. In this mode the channel signal will be sent to the AUX1 output using the channel AUX 1
control knob in conjunction with the channel fader. So when using AUX 1 for a mix being sent to an effects proces-
sor, the Aux 1 knob, and the channel fader both control the overall level sent to the AUX1 output. If you are sending
to a delay or reverb, when you push the channel fader up you are sending more signal to the delay or reverb. Pull
the fader down and you are sending less level to the delay or reverb. Keep in mind that when the AUX 1 is in POST,
the Aux send follows the fader.

AUX 2 / DSP Send
The MDR16 provides high quality, 24 Bit digital effects, and the level of effects can be set independently on
each channel. The channel's AUX 2/DSP knob controls the amount of signal that is sent to the AUX 2/DSP bus.
The signal of the AUX 2/DSP bus is routed to the internal DSP effects section for onboard signal processing. The
AUX 2/DSP signal can also be sent to an external effect device connected to the AUX 2 OUT jack located in the
MASTER SECTION jack field.
NOTE: The channel's AUX 2/DSP signal is sent to the AUX 2/DSP bus from a location in the signal path after the
channel's LEVEL control. This is commonly referred to as a POST FADER send. This means that the amount of signal
that is sent to the EFFECT bus will be affected not only by the setting of the AUX 2/DSP knob control, but it will also
be affected by the setting of the LEVEL control.
11
PAN
The MDR16's PAN control is used to place or position the mono signal into the stereo main Left and Right MIX bus.
You can create a stereo image by panning some input signals to the left and others to the right. The MDR16's PAN
control is a Power-Pan circuit, which includes a 3dB dip in the center position. This is desirable since there's a 3dB
increase in gain when the mono input signal is heard at the same level in both the Left and Right MIX bus.
