Using this manual : T o get the most out of your 424 MKIII, please take the time to read through this manual. Some time spent now will keep you from overlooking some of the features that make the 424 MKIII a more creative tool. Y ou may discover some new tricks you haven't tried before.
5 The POR T ASTUDIO 424 MKIII is a complete audio production facility in a single box. It is divided into two major sections: a full-function mixer and an 4-channel, multitrack cassette recorder .
6 jacks. This is the most important signal route in the mixer and is called "Main Mix". The illustration below shows how input signals pass through the 424 MKIII Mixer section.
7 T ape Cue Monitor System The T APE CUE mix and MONITOR switches are also crucial for successful multitrack recording, because they control what you hear in the headpnones.
8 ∑ A three-point autolocator (MEMO/LOC 1 and 2 and R TZ) lets the tape STOP at, or PLA Y from preset points. ∑ REPEA T allows a section to be played over and over between the MEMO 1 and MEMO 2 points.
9 T ape Speed and T rack Format The Portastudio 424 MKIII uses a HIGH speed of 9.5 cm/sec. (3-3/4 inches per second) which is two times (2X) the normal speed of a standard audio cassette. Its NORMAL speed is 4.8 cm/sec (1-7/8 i.p.s.), the same as that used by conventional recorders.
10 Accidental Erase/Record Protection T o protect a finished master tape, it is necessary to punch out both record protect tabs. Even though you are recording in only one direction, the 424 MKIII uses the entire width of the tape, as mentioned above.
Ch 7-8 STEREO INPUT : Connect any stereo line-level signal (such an effect return or electronic instrument) here. Alternatively , you can connect two mono line-level signals. MONO feature: If only one mono signal is to be connected, connect it to the L jack, and leave the R jack unconnected.
13 Recorder Controls RECORD FUNCTION 1-4 : These control which track(s) will be recorded when the master RECORD and the PLA Y key is pressed, and choose where the signal to be recorded is coming from. œ Setting to DIRECT routes the channel signal directly to the tape (channel 1 is recorded on track 1, channel 2 on track 2, and so on).
Input connections Powering on Headphone connection Routing inputs Let’ s try the 424 MKIII mixer T o learn how the mixer works, first you need to plug a signal source into one of the 1-8 jacks located at upper top of the unit, in your easy reach. As an example, we'll use a microphone as the source.
Panning Channel level Master level Monitor selection TRIM adjustment Listening level 6. T urn the channel 1 P AN control all the way to the left. 7. Raise the channel fader to "7" on the scale. 8. Raise the MASTER fader to "7". 9 .
Resetting the counter Selecting tracks Mic level adjustment Beginning to record Stopping recording Putting track into "Safe" 4 . Press the COUNTER RESET switch, so you can use the R TZ (Return-T o-Zero) function to get back to this point. 5 .
Switching T APE CUE on Monitor selection Locating tape to zero Begin to play Listening level adjustment Routing tape signals to T APE CUE Stop play T rack 1 playback through T APE CUE 1. Set the EFFECT 2/T APE CUE selection switch located below the LEVEL control to the right/T APE CUE position.
19 Routing input Panning Channel 1 level Master level Monitor selection Locating tape to zero T rack selection Record level adjustment (TRIM) How to make an overdub on track 2 Overdubbing entails recording one or more additional tracks on the same tape, while listening to previously recorded tracks using T APE CUE.
20 How to record tracks 3 and 4 How to record many sources onto a single track 9. Hold RECORD and press PLA Y to initiate recording. The REC "2" indicator that was blinking will turn on solid, indicating track 2 is now being recorded. 10. Y ou will hear track 1 play , together with the new signal going to track 2, in the headphones.
21 How to record a mix onto two tracks simultaneously œ Set the P AN control of each channel to the same setting, for example : In this example, all instruments plugged into channels 1-4 will be recorded onto T rack 1 or 3.
22 Recording on more than two tracks simultaneously : DIRECT ∑ Set the MONITOR SELECT LINE OUT switch to L-R or MONO, and set the EFFECT 2/T APE CUE switch to T APE CUE if you need to hear tape tracks or MIDI virtual tracks. Recording is the same procedure as for one track.
23 Connections Master level Monitor source Routing inputs Playback level How to mix down When the 4 tracks are all recorded, the final step is mixing them into a standard stereo format. This procedure is known as Remixing or Mixing down. During this procedure the tracks are blended together and balanced to create the desired sound.
24 Review Record level 8. When the signal balance, level, and tonality sound right, rewind the tape, and press PLA Y again to check the result. 9 . Rewind the multitrack tape again. Put a blank tape in the mixdown deck and let it play for 5 seconds, then stop it and reset the mixdown deck's counter to zero.
25 Using Memory Location P oints MEMO 1 MEMO 2 Establishing new MEMOs Recalculation of MEMOs Checking MEMO points Erasing Loading MEMO points T wo autolocation points can be established in the 424 MKIII's memory system. At the desired moment, hold the MEMO IN key and press the LOC 1 key .
26 T o zero T o MEMO 1 T o MEMO 2 Auto play Locating the tape Press the R TZ key to fast wind the tape to the counter zero point. If you press COUNTER RESET during the RTZ process, the tape counter is reset to 0000 and the tape stops. Hit the LOC 1 key to fast wind the tape to the MEMO 1 point.
27 Repeat Pla y Operating procedure T o interrupt REPEA T sequence Note 1 Note 2 The REPEA T function provides a "Playback Loop" or "Block Repeat" between the two programmed MEMO points. The 424 MKIII understands the lower MEMO point as the start point of the loop, and the higher point as the end.
28 PUNCH-IN or INSER T Recording Selecting in and out points "Punching in" or "insert recording" is recording over a small section of previously recorded track to correct or improve a performance, while keeping the rest of the track intact.
29 Rehearsing Punch-in (Insert) recording Storing the punch-in and out points into memory Rehearsal and Auto In/Out Procedures Y ou can rehearse your punch-in as many times needed without affecting the existing recording.
30 When the tape reaches the preset punch-out point, you will be able to hear the old material existing on track 2, letting you check that the new material is smoothly followed by the old one. The RECORD LED will turn off, indicating that the "dry-run" record is over .
31 Manual Punch-in 8. Press the AUTO PUNCH switch. "RHSL" will turn off and "AUTO" will start blinking in the display . 9. Press PLA Y . What you have anticipated in REHEARSAL will automatically occur in sequence: preroll, punch in, punch out, postroll, rewind, and stop.
32 Using the remote footswitch (RC-30P) If you are recording alone and are too busy playing an instrument to push the switches, the optional remote footswitch really comes in handy . 1. Plug the RC-30P into the REMOTE PUNCH IN/OUT jack on the rear panel of the 424 MKIII.
33 The recording capability of the POR T ASTUDIO 424 MKIII is not limited to four tracks. Y ou can "bounce" or combine tracks you have recorded to an empty track, and then replace the original tracks with new material.
34 6 . Use channel faders 1 through 3 to make any necessary level adjustments. Y ou may want to repeat this step several times to get the balance correct. 7. When the balance is right and the level is peaking at no more than +6 on the track 4 meter , stop and rewind the tape to the beginning of the track.
Using Effects With the POR T ASTUDIO 424 MKIII 35 Effects and signal processing are areas where you can really start to have fun customizing your sound, and develop your own unique recording style. Because there are so many possibilities, it also can be confusing.
36 T o record reverb onto a track : Switch the ASSIGN switch to L-R, and adjust the controls for the sound you want. Remember that stereo signals must be recorded onto two tracks to keep their "stereo" effect.
Problem Solution Old tracks are always recorded along Use the T APE CUE section instead of the with new material. main mixer for monitoring previous tracks. Make sure all mixer channel INPUT switches are in the OFF position except ones you are Recording is noisy .
424 MKIII MIXER 1. POWER switch (on the rear panel): T urns 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.
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. T urn the control to the right to increase volume to the EFFECT 1 SEND jack.
42 424 MKIII RECORDER 29 . Cassette compartment door: T o 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.
This can be used to save slightly out-of-tune parts, or to create sound effects such as flanging. Note that if you record with the dial at its maximum or minimum setting, you will NOT be able to make further adjustment in that direction upon playback.
44 Autolocators 41. Monitor level meters: These show the level in the monitor mix selected by the MONITOR switches (#18). The meters are "Pre" (before) the rotary MONITOR LEVEL control, so this control does not affect the meter readings. 42.
46 45 49 . CLEAR key: T urns off the REHEARSAL and AUTO PUNCH IN/OUT functions (pp.30-31). 5 0 . COUNTER RESET switch: This resets the COUNTER to "0000" so you can assign any point on the tape as a starting location. Pressing R TZ (#44) gets you back to that location.
