4 Gain
Individually sets the gain of each head amplifier channel.
Edit using the “Numeric Parameters” editing procedure
described on page 36.
5 +48V
Individually turns phantom power ON or OFF for each
head amplifier channel.
Use the [
E] and [F] keys to position the cursor at the
desired channel, then press the [ENTER] key to alternately
turn phantom power for that channel ON and OFF.
• Always turn the phantom power off when it is not
needed.
• When turning phantom power ON, make sure that no
equipment other than phantom-powered devices such
condenser microphones are connected to the [IN]
connectors (DME24N only). Applying phantom power
to a device that does not require phantom power can
damage the device.
• Do not connect or disconnect a device to a [IN]
connector (DME24N only) while phantom power is
applied. Doing so can damage the connected device
and/or the unit itself.
• To prevent speaker and possible hearing damage, be sure
to turn power amplifiers OFF when turning phantom
power ON or OFF. It is also a good idea to turn the
output level all the way down (page 39).
6 Phantom Master Switch (AD8HR only)
Displays overall phantom power ON or OFF.
7 High-pass Filter (HPF) (AD8HR only)
Individually turns the high-pass filter for each AD8HR
head amplifier channel ON or OFF. This parameter is only
available for the AD8HR head amplifier. Use the [
E] and
[
F] keys to select a channel, then press the [ENTER] key
to turn the HPF for that channel ON or OFF.
8 High-pass Filter Frequency (Frq) (AD8HR
only)
Individually sets the high-pass filter frequency for each
AD8HR head amplifier channel. This parameter is only
available for the AD8HR head amplifier.
Edit using the “Numeric Parameters” editing procedure
described on page 36.
Cascade Setup (CASCAD) Page
Shows the status of the [CASCADE] connectors. Refer to
“CASCADE Connection” on page 31 for connection
details.
Settings are made from the DME Designer application
running on the connected computer.
1 Head Margin
Sets the head margin for cascade connection.
-18dB: Use this setting when cascading DME64N units
or when connecting to a mixer’s normal cascade bus.
0dB: Use this setting when connecting to a PM5D in
situations in which the PM5D SLOT OUT port signal is
being output via the CASCADE OUT terminal.
2 Unit No
Shows how many devices the unit is from the beginning of
the cascade chain.
NOTE
The gain of the DME24N internal head amplifiers can be
adjusted from +10 dB to –60 dB in 1-dB increments. The
internal circuitry switches at about the –45-dB point, and the
signal is automatically muted at that point to prevent noise.
The AD8HR gain can be adjusted from +10 dB to –62 dB in
1-dB steps, and the AD824 gain can be adjusted from +10 dB to
–62 dB in 6-dB steps.
The PAD will be internally switched on or off when the gain of
the DME24N built-in head amplifier is adjusted between -8 dB
and -7 dB. Keep in mind that noise may be generated if there is a
difference between the Hot and Cold output impedance of the
external device connected to the IN connector when using
phantom power.
CAUTION
NOTE
This page only appears on the DME64N.
NOTE
The Head Margin setting only applies when connected to a
mixer. When not connected to a mixer the head margin is
automatically set to 0 dB.
