ADAT XT Reference Manual 53

FOOTSWITCH CONTROLS

The XT provides two footswitch jacks: [LOCATE/PLAY/LRC REMOTE] and [PUNCH

IN/OUT]. Both accept any momentary, single pole/single throw, 1/4-inch mono (T/S)

footswitch. During power-up, the XT checks the footswitch to determine whether it is

normally open or normally closed type, and calibrates itself accordingly. If you use a

footswitch and its operation seems “reversed,” make sure it is firmly plugged into the

jack, then turn off the XT, wait a few seconds, and turn the XT on again. It will

calibrate itself to work with the footswitch.

Either the [PUNCH IN/OUT] or [LOCATE/PLAY/LRC REMOTE] jack can also be

used for connecting an LRC Remote Control. The PUNCH footswitch and the LRC

cannot be used at the same time, since they occupy the same jack, unless you

connect them with a Y-cord. However, you can interchange them if you observe

certain precautions (see next section).

FOOTSWITCH CONTROLLED PUNCHING

The [PUNCH IN/OUT] footswitch is used to enable and disable recording.

• If a track (or tracks) is record-enabled, and the tape is playing, pressing the

punch footswitch puts the track(s) into record mode at the instant you punch. This

is equivalent to pressing [PLAY] and [RECORD] to enter record mode.

• If the XT is already in record mode, pressing the footswitch punches out of record

(the track(s) will remain record-enabled should you need to punch in again later

on) and the tape will continue to play. This is equivalent to pressing [PLAY].

FOOTSWITCH CONTROLLED AUTOLOCATING

The [LOCATE/PLAY] footswitch has three functions:

• If the transport is currently stopped, pressing the Locate/Play footswitch is the

equivalent to pressing the [PLAY] button.

• If the transport is currently playing or recording, pressing the Locate/Play

footswitch causes the transport to punch out of record, fast wind to the Locate 1

point (this may be entered by pressing [SET LOCATE] followed by the [LOCATE

1] button; see page 47), and then either Stop or Play, depending on the setting of

the Auto-Play function.

• If the XT is in the process of locating, pressing the Locate/Play footswitch will

stop the transport.
