Features and Controls

424 MKIII MIXER

1. POWER switch (on the rear panel): Turns the

424 MKIII on and off.

2. Power connector: Connect the power adaptor for the 424 MKIII to this connector. It is important that you use only a power adaptor specially designed for the 424 MKIII which is designed for use with the voltage in your area.

Input Section

3. MIC/LINE INPUTS jacks, Balanced (Channels 1-4): The 3-contactXLR-type connector accepts balanced microphone signals ranging from –60 dBV (1 mV) to –20 dBV (100 mV), depending on the setting of the TRIM control (#6).

4. MIC/LINE INPUTS jacks, Unbalanced (Channels 1-4): This 1/4" jack accepts unbalanced signals ranging from –50 dBV (3 mV) to –10 dBV (0.3 V), depending on the setting of the TRIM control (#6).

NOTE

■ DO NOT use both the XLR-type and 1/4" phone jacks on the same channel at the same time.

5. SUB INPUT L and R jacks: These jacks are for cascade connection of an outboard mixer, etc. The signal input to these jacks is sent to the MASTER fader. Nominal input level is –10 dBV (0.3 V).

The SUB IN R jack is also used to accept FSK- converted MIDI sync signals from devices such as the optional TASCAM MIDI-Tape Synchronizer MTS-30.

6. TRIM controls: This is used to set preamplification level on the MIC/LINE INPUTS. When TRIM is turned all the way to the left (LINE position), the preamplifier gain is low, allowing the jack to accept line level sources such as electronic instruments. As you turn TRIM up, the preamplifier gain increases, and when you turn TRIM full clockwise (MIC position), the nominal input sensitivity increases to –50 dBV (3 mV) for 1/4" phone jack, and to –60 dBV (1 mV) for XLR-type jack.

7.INPUT select switches:

(channels 1-4)

This is used to control what the source of the channel is:

The left position (MIC/LINE) is used when recording microphones/instruments (in tracking or overdubbing).

The center position (OFF) is used to shut off the channel.

The right position (TAPE) is used during mixdown or bouncing tracks.

(channels 5 and 6)

This is used to control the source of these channels. Channel 5 can accept the signals from equipment connected to odd-numbered inputs 1, 3 and 5, and channel 6 uses the even-numbered inputs in the same way. Slide the switch to the appropriate number to send the signal from the appropriately-numbered input to the channel.

Note that if signals are sent through more than one channel at the same time (e.g. through channel 1 and 5), the level of these signals will be doubled. You should allow for this when mixing.

8.EQ HIGH: This controls the tonality of the high or "treble" frequencies. Turn it to the right to boost the signal's high frequency content emphasizing brilliance or brightness. Turn it to the left to cut the high frequency content, if the signal sounds too harsh or shrill. The EQ shelving point is 10 kHz.

9.EQ MID: The upper knob changes the center frequency of the MID equalizer from 250 Hz to 5 kHz. The lower knob controls how much cut or boost is applied to the band chosen by the upper knob. Turning the lower knob to the right amplifies the band up to 12 dB. Turning it to the left cuts the band down to –12 dB. At center, there is no effect (flat response).

10.EQ LOW: Turn the control to the right to boost bass frequencies and make the sound relatively heavy. Turn the control to the left to cut bass and make the sound thinner. The EQ shelving point is 100 Hz.
