424 MKIII MIXER1. POWER switch (on the rear panel): Turns the424 MKIII on and off.2. Power connector: Connect the power adaptorfor the 424 MKIII to this connector. It isimportant that you use only a power adaptorspecially designed for the 424 MKIII which isdesigned for use with the voltage in yourarea.3. MIC/LINE INPUTS jacks, Balanced (Channels1-4): The 3-contact XLR-type connectoraccepts balanced microphone signalsranging from –60 dBV (1 mV) to –20 dBV(100 mV), depending on the setting of theTRIM control (#6).4. MIC/LINE INPUTS jacks, Unbalanced(Channels 1-4): This 1/4" jack acceptsunbalanced signals ranging from –50 dBV(3 mV) to –10 dBV (0.3 V), depending on thesetting of the TRIM control (#6).5. SUB INPUT L and R jacks: These jacks are forcascade connection of an outboard mixer,etc. The signal input to these jacks is sent tothe 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 devicessuch as the optional TASCAM MIDI-TapeSynchronizer MTS-30.6. TRIM controls: This is used to setpreamplification level on the MIC/LINEINPUTS. When TRIM is turned all the way tothe left (LINE position), the preamplifier gainis low, allowing the jack to accept line levelsources such as electronic instruments. Asyou turn TRIM up, the preamplifier gainincreases, and when you turn TRIM fullclockwise (MIC position), the nominal inputsensitivity increases to –50 dBV (3 mV) for1/4" phone jack, and to –60 dBV (1 mV) forXLR-type jack.NOTEn DO NOT use both the XLR-type and 1/4"phone jacks on the same channel at thesame time.Input Section39Features and Controls407. INPUT select switches:(channels 1-4)This is used to control what the source of thechannel is:The left position (MIC/LINE) is used whenrecording microphones/instruments (intracking or overdubbing).The center position (OFF) is used to shut offthe channel.The right position (TAPE) is used duringmixdown or bouncing tracks.(channels 5 and 6)This is used to control the source of thesechannels. Channel 5 can accept the signalsfrom equipment connected to odd-numberedinputs 1, 3 and 5, and channel 6 uses theeven-numbered inputs in the same way. Slidethe switch to the appropriate number to sendthe signal from the appropriately-numberedinput to the channel.Note that if signals are sent through morethan one channel at the same time (e.g.through channel 1 and 5), the level of thesesignals will be doubled. You should allow forthis when mixing.8. EQ HIGH: This controls the tonality of thehigh or "treble" frequencies. Turn it to theright to boost the signal's high frequencycontent emphasizing brilliance or brightness.Turn it to the left to cut the high frequencycontent, if the signal sounds too harsh orshrill. The EQ shelving point is 10 kHz.9. EQ MID: The upper knob changes the centerfrequency of the MID equalizer from 250 Hzto 5 kHz. The lower knob controls how muchcut or boost is applied to the band chosen bythe upper knob. Turning the lower knob tothe 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 (flatresponse).10. EQ LOW: Turn the control to the right toboost bass frequencies and make the soundrelatively heavy. Turn the control to the left tocut bass and make the sound thinner. The EQshelving point is 100 Hz.
