INSTALL
For each input channel (A/B/C/D) is a female XLR connector. Even channel
numbers are for analogue inputs only.
Analog signal input:
The HOT, "+" or "in phase" connecon should be made to pin 2 of the XLR
connector.
Pin 1 of the XLR connector is internally connected to the chassis.
The AC voltage provided by the audio processor with built-in global voltage
operaon must be within ±10% of the specified line voltage (90/240V~). The
third pin (grounding pin) on the power cord that comes with the package is a
necessary safety component; please do not try to disable the ground
connecon by using an adapter or other methods.
AC POWER INPUT
SIGNAL INPUT AND OUTPUT
Like all digital signal processing equipment, the signal level supplied to the
unit must be appropriate to avoid working in a low signal-to-noise rao or
distoron. The DLM series processors can accept up to +20dBu analog signal
level, which is greater than the linear output level of most mixers, so the
impact of this type of problem is reduced. When performing equalizaon
processing, pay aenon to the boosted gain value not to be too large, so as
to avoid the gain of the unit from causing digital clipping (of course, you can
use the built-in an-clipping funcon to prevent this event from happening).
It must be noted that the maximum input level in the specificaon is a clipping
level, not a safe praccal level. It must be ensured that the clipping level is not
lower than the next device in the signal chain and a certain margin must be
le during use.
The COLD, "-" or "out of phase" connecon should be made to pin 3 of the
XLR connector.

1) 2 * 24 alphanumeric display
5) INPUT SIGNAL LEVEL METERS: these meters display the Input signal
level before the Input Gain: MUTE does not affect the displayed level; the
MUTE status is shown by the "mute led" which turns red when the related
channel is muted; when the SIG led is on, it means the input signal reaches
the -40dBu; -12dBu, 0dBu, +6dBu, +12dBu represent the actual RMS
value of the signal; the CLIP/OVER led is on to indicate that the signal is
exceeding the maximum level before the A/D analog-to-digital
conversion OR that an internal Overflow is occurring due to excessive
added gain on the signal path (normally the Overflow is controlled by an
internal process and doesn't bring to signal distoron, but need to
decrease the signal level along the path); the LIMIT light will turn on when
the Input RMS Compressor is operang a dynamic control.
9) OUTPUT CHANNEL SELECTION KEY: short press this key to edit the
parameters of the output channel processes (Gain, Polarity, Delay, Xover,
Parametric EQ / RMS compressor) or general parameters as the channel
inputs to output channel Matrix. Press and hold for three seconds to mute
the current channel.
6) OUTPUT SIGNAL LEVEL METERS: these meters display the Output signal
level before the output Gain, therefore aer the all processes: MUTE
affects the displayed level; the MUTE status is shown by the Mute led
which turns red when the related channel is muted; when the SIG led is on,
it means the input signal reaches the -40dBu; -12dBu, 0dBu, +6dBu,
+12dBu represent the actual RMS value of the signal; the OVER led is on
to indicate that an internal Overflow is occurring due to excessive added
gain on the signal path ( normally the Overflow is controlled by an internal
process and doesn't bring to signal distoron, but need to decrease the
signal level along the path); the LIMIT light will turn on when the Output
RMS Compressor or/and the Output Peak Limiter is/are operang a
dynamic control.

COMPRESSOR
RMS compressor reduce the start threshold to use the compressor to
control the dynamics of the input signal. Using a lower start me (such as
5ms) and a higher release me (such as 1000ms) can firmly control the input
signal within a certain range, of course, this will bring an obvious sense of
compression (flatness).
Seng different start/release mes in combinaon with music types will
bring different listening feelings, and make up can also be used to
compensate for the loss of loudness; and with a variable knee seng, the
default 0 is the hard knee and the threshold is the compression starng
point; 100% is the so knee when the compression starng point is lower
than the set threshold and gradually exceeds the threshold to achieve full
effect.
Under high compression raos, it is easy to hear unnatural and abrupt
sounds when using hard knees. On the contrary, using so knees can make
the compression transion smoothly and bring a natural sense of hearing.
