Tascam 424MKIII owner manual Mkiii Recorder

24.EFFECT 1 SEND jack : The signal available at this jack comes from post-fader, for connection to effects devices. Nominal level is –10 dBV (0.3 V).

25.EFFECT 2 SEND /TAPE CUE OUT jack: This jack is for connection to an additional effects device, or to a studio speaker amplifier. The signal source is determined by the EFFECT 2/TAPE CUE select switch (# 20). Nominal output level is –10 dBV (0.3 V).

26.TAPE OUTPUTS 1-4:These jacks get signal directly from the tape (jack 1 from track 1, jack 2 from track 2, and so on). Use them if you want to mix the tape down with an external mixer or to make a backup copy of your master 4-track onto another tape recorder.

Sync tones recorded on track 4 are sent out of jack 4, for MIDI instruments to play synced up to the tape.

27.PHONES jack (on the front panel): Connect any stereo headphones with a 1/4" stereo TRS 3-conductor plug to this jack.

28.REMOTE PUNCH IN/OUT jack: For connection to an optional RC-30P remote footswitch.

Cassette Loading and dbx System

29.Cassette compartment door: To access the cassette compartment for inserting or removing a cassette, or cleaning the heads, etc., lift the door, using the tab at the lower right corner of the door. Once a cassette is inserted, be sure to close the door to prevent objects, dust or liquids from falling into the tape path.

Tape path components

30.DBX NR switch: When this switch is set to its ON position, the built-in dbx noise reduction system for all 4 tracks is turned on. This is the normal position for all recording and playback.

When it is set to the SYNC position, Track 4 is disconnected from the dbx system, so the process does not affect the sync signals going to and from track 4, but tracks 1-3 still go through the dbx encode/decode process. Use the SYNC position for recording and playback of FSK sync or SMPTE time code.

The OFF position turns off the dbx noise reduction completely. Use this position when playing back tapes made with no noise reduction, or with Dolby B type NR.

The dbx NR system provides a net noise reduction (broadband, not just hiss) of about 30 dB, and also permits a net gain in tape headroom of about 10 dB, allowing recordings over a 90 dB dynamic range.
