2 WCLK (AD8HR/AD824 only)
Specifies the word clock signal to be used by the head
amplifier(s).
Available settings of the AD8HR are “D OUT A,”
“WCLK IN,” “INT44.1K,” “INT48K,” “INT88.2K,” and
“INT96K.”
D OUT A: Sets the word clock signal at the digital input
as the master clock of the AD8HR.
WCLK IN: Sets the word clock signal at BNC connector
as the master clock of the AD8HR.
INT44.1K: Sets the 44.1 kHz internal word clock as the
master clock of the AD8HR.
INT48K: Sets the 48 kHz internal word clock as the
master clock of the AD8HR.
INT88.2K: Sets the 88.2 kHz internal word clock as the
master clock of the AD8HR.
INT96K: Sets the 96 kHz internal word clock as the
master clock of the AD8HR.
Available settings of the AD824 are “SLOT,” “BNC,”
“INT44.1K,” and “INT48K.”
SLOT A: Sets the word clock signal input via I/O cards
installed in the I/O slots as the master clock of the
AD824.
BNC: Sets the word clock signal at the BNC connector as
the master clock of the AD824.
INT44.1K: Sets the 44.1 kHz internal word clock as the
master clock of the AD824.
INT48K: Sets the 48 kHz internal word clock as the
master clock of the AD824.
3 Format (AD8HR only)
Displays the 88.2/96 kHz audio signal transfer mode. The
input setting is on the left and the output setting is on the
right.
No Display (default): 44.1/48 kHz audio signal
transfer.
SP (Double Speed): Allows direct transfer at 88.2 or
96 kHz.
CH (Double Channel): 88.2 or 96 kHz audio is
transferred by using two 44.1/48 kHz channels to transfer
each audio channel of 88.2 and 96 kHz respectively. The
number of audio channels that can be handled in this
mode is half the number of channels normally handled by
the AD8HR.
4 Gain
Individually sets the gain of each head amplifier channel.
Edit using the “Numeric Parameters” editing procedure
described on page 35.
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.
• Phantom power should only be used with phantom-
powered condenser microphones. Turning phantom
power ON when other types of equipment are
connected can result in damage. Balanced dynamic
microphones, however, will not be affected by phantom
power.
• 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 38).
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 35.
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.
