GAIN section

1 [GAIN] encoder and LEDs

If an AD card with head amp is patched to this chan-

nel, this encoder sets the input sensitivity of the head

The range of levels is +10dB — –68 dB.

The approximate current setting is shown by the

perimeter LEDs.

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.

This section attenuates the level of the input signal.

1 [ATTENUATOR] encoder and LEDs

This encoder attenuates the signal level of the

selected channel, and immediately before the HPF.

The range is –96 dB – 0 dB (1 dB steps), and the

approximate current value is shown by the perimeter

2 GAIN [CLIP] LED

This LED will light if the input signal of the input

channel clips.

If this LED lights for an input channel to which an

AD card with head amp has been patched, use the

[GAIN] encoder ( 1 ) to lower the input sensitivity.

If this LED lights for an input channel to which an

AD card without head amp or a digital I/O card has

been patched, lower the output level of the sound

source that is connected to the card.
