If you wish to use phantom power, you must also
turn on the +48V switch located on the front panel
of the AI8 input unit. If this switch is off, no phan-
tom power will be supplied to the cards installed in
that unit.
4. While watching the level meter, drag the on-screen
GAIN knob to adjust the input sensitivity of the
channel.
The GAIN knob adjusts the input sensitivity of the
head amp. The supported range of levels is 10 dB —
–68 dB, and the current value is shown in the numer-
ical box located immediately below.
Hint
As an alternative to the on-screen knob, you can also
adjust the input sensitivity using the INPUT [GAIN]
encoder of the INPUT block. In this case, the periph-
eral LEDs around the encoder will indicate the
approximate value.
The PAD will be internally switched on or off when
the gain of the LMY4-MLF card (including the AI8-
ML8F unit) internal head amp 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 card when using phantom power.
5. If you want the gain or input jack A/B selection to
be linked between adjacent input channels in the
screen, turn on the GAIN GANG button and A/B
LINK button for each channel.
If the GAIN GANG button is on, gain settings will be
linked while preserving the level difference between
channels. If the A/B LINK button is on, the A/B input
jack selection will be linked. Be aware that even if the
A/B LINK button is on, link will not be valid until
the A/B button is switched for one of the channels.
