Stereo Input Section

11.EFFECT 1 send controls: These controls get their signal from a point just after the channel fader (i.e., "post fader send") and route the corresponding channel signal to the EFFECT 1 SEND jack. Turn the control to the right to increase volume to the EFFECT 1 SEND jack.

12.EFFECT 2/TAPE CUE controls: These controls get their signal after the channel fader and route the signal to the EFFECT 2 SEND jack, or are used to adjust the tape playback level sent to the monitor section, as determined by the MONITOR EFFECT 2/TAPE CUE select switch.

13.PAN controls: This control allows you to create stereo mixes by sending the signal from the channel fader in continuously variable degrees to the left or right sides of the stereo mix at mixdown time.

14.Channel Faders:This linear control varies the level feeding the Master section.

The nominal setting position is between 7 and 8 (shaded area).

15.STEREO INPUT jacks: Connect the outputs of your effects devices to these 1/4" jacks. These jacks can also be used as additional line inputs. Nominal input level is –10 dBV (0.3 V).

Mono Feature: If you connect a mono signal to the 7/MONO jack, the signal is sent to both the stereo left and right busses.

16.LEVEL control: This rotary control varies the level feeding the Master section.

The nominal setting position is about 2 o'clock.

17.ASSIGN switch: This send the signal from the LEVEL control to the MASTER (L-R), switches it off entirely (OFF) or to the MONITOR LEVEL control (MON). If you are using these inputs for MIDI “virtual tracks”, you should probably set this switch to MON while recording tape tracks, and L-R on mixdown.

Monitor Section

18.MONITOR SELECT switches: These switches determine what you will hear when monitoring.

The LINE OUT switch allows you to monitor in stereo (L-R), in mono (MONO) or turn off the L-R signals completely from the monitoring mix (OFF).

The EFFECT/CUE switch allows you to choose whether you will hear the EFFECT 1 send, the EFFECT 2 or TAPE CUE send (as determined by the position of the EFFECT 2/TAPE CUE switch), or neither of these (OFF).

19.MONITOR LEVEL control: This affects signal from the MONITOR select switch and sets the level you'll hear in the headphones/monitor speakers.

Master Section

20.EFFECT 2/TAPE CUE select switch : Depend- ing on the setting of this switch, each channel's EFFECT 2/TAPE CUE control is switched to send the mic/line input to effects devices or the signal coming back from the recorder to the musicians in studio.

21.MASTER fader : Used to adjust the stereo mix level. The signal fed to this fader comes from each channel's PAN control. The safe operating zone is between 7-8 on the scale.

Output Section

22.LINE OUTPUT L and R jacks: These jacks are the line-level outputs from the MASTER fader. The L and R jacks are typically connected to your 2-track master recorder at MIXDOWN. The LINE OUTPUT jacks can also be used to send the mixer outputs of the 424 MKIII to the sub inputs of a larger mixer.

23.MONITOR OUTPUT L and R jacks: These provide a line level version of the same signal that feeds the PHONES jack and may be connected to your control room speaker amplifier.
