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. Use of capital letters : In general, we use all upper cas[...]

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 . T o complete the recording system, you'll additionally need these: Input devices (microphones, instruments), Output devices (headphones), 2 track re[...]

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. After the MASTER fader they go to the L/R LINE OUT Signal Flow in the 424 MKIII Mixer Understanding the Mix er[...]

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. This CUE mix is totally independent from the Main Mix going to tape. If you don't use the CUE mix, you run the risk of accidentally "bouncing tracks" every time [...]

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. ∑ REHEARSAL programs the 424 MKIII to repeat a punch-in/out sequence as many times as you wish, and AUTO PUNCH actually executes it on tape ex[...]

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. It also employs a discrete 4-channel format head developed especia[...]

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. If, for example, you remove only one of the tabs, you could accidentally insert the cassette into t[...]

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. The signal is automatically taken to both the 7 and 8 cha[...]

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). Recording le[...]

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. 1 . Have to hand a dynamic micr ophone and [...]

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. NOTE:[...]

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. If you want to record multiple sources onto two tracks, you use the channel P AN controls to send them to LEFT or RIGHT (or a[...]

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. In the example above, set both the TRK 3 and TRK 4 RECORD FUNCTION switch[...]

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. 1. Connect the L[...]

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. 10. Press PLA Y on the 424 MKIII. 11[...]

If you hold it down fo[...]

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. 1. Use MEMO IN and LOC 1 and LO[...]

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. The mixer settings should be exactly the same as they were during the original recording.[...]

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. During rehearsal, what you hear in the monitor mix and read on the level meters will be the same as during recording, but signal[...]

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 . After 3 seconds of play ("postroll") the tape will automatic[...]

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. "AUTO" will be solidly displayed when the 424 MK[...]

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. 2. Check that the REC 2 indicator is blinking, and locate the tape to a point [...]

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. A bounce is like a mixdown, except you are recording to one of the tracks of the 424 MKIII instead of to an external reco[...]

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. 8 . Hold RECORD and press PLA Y . The REC 4[...]

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. There are many different effect units on the market, all with different controls, typ[...]

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. CAUTION: The PITCH CONTROL dial affects recording speed also. Check to make sure that the dial is [...]
