A +48V ON/OFF switches 1–16
These switches turn on or off the +48 V phantom power feed to each INPUT.
B PAD switches 1–16
These switches turn on or off the 20 dB pad (attenuator) for each AD Input.
C GAIN controls 1–16
These controls adjust input sensitivity for each AD Input. Input sensitivity is +4 dB to
–40 dB when the Pad is on, and –16 dB to –60 dB when the Pad is off.
D PEAK indicators 1–16
These indicators light up when the input signal level is 3 dB below clipping. Adjust the Pad
switch and GAIN control so that the indicator rarely lights up at signal peak.
E SIGNAL indicators
These indicators light up when the input signal level is 20 dB below nominal.
Note: Screw holes for attaching a cover are located at both sides of the AD input section of the
DM1000. (Size M3, horizontal spacing 417 mm, vertical spacing 36 mm.) You may wish to
fabricate your own cover and attach it to the front panel to prevent the controls from being
operated inadvertently. Yamaha does not sell such a cover. If you fabricate and attach your
own cover, make sure that the mounting screws do not extend more than 10 mm into the front
panel. You will need to allow approximately 15–20 mm between the top panel and the cover
in order to clear the control knobs and buttons.
