The X55 is a 4-track, 4-channel multitracker .
The machine features footswitch punch-in/out recording, but if you want to make use of this, you'll have to provide your own footswitch.Simultaneous recording is possible on all four tracks, which is a plus, as many similarly priced units only allow you to record on a maximum of two tracks at once. In practical terms, this means you could record a whole band at once, whereas the more limited machines are better suited to the solo musician building up a recording one or two tracks at a time.Fostex have stuck with Dolby C noise reduction, which seems to provide a realistic compromise between noise reduction and audible side effects without going to the more costly Dolby S system.
The X55 also features pitch control, high and normal tape speed, insert points on two of the mixer channels, two Aux sends, three-band EQ, a sync facility on track 4, and direct tape outputs. The latter provision is very important if you want to mix down via an external mixer with better facilities.
The machine weighs in at a mere 3kg and is extremely compact, measuring only 405 x 321 x 105mm.
Overall, the X55 looks to be well thought out, but a more thorough rundown of the inputs and outputs may help you decide if it's exactly what you need. On the front panel are the input jacks 1-4; 1-4 are designed to handle line levels, such as electronic instruments.In addition, there's a jack for headphones and one for the optional punch in/out footswitch. The rest of the connections are on the rear panel. There are two insert jacks, which you can use to process individual signals while you're recording to tape or during mixdown -- typical applications would be using a compressor/limiter on vocals, or recording an instrument or voice complete with its effects, thus freeing the signal processor to be used with a different setting when you come to mix. The Aux Sends and stereo Returns are mono jacks.Also 2 XLR sockets are provided for balanced mike input. There are several sets of output jacks, the first labelled Foldback, which is a single, mono jack; this might be used to feed a headphone amplifier for the benefit of the musicians in the studio. Next come the Stereo Out jacks, for connecting to the input of your 2-track mastering machine for mixdown. Monitor Outs provide the signal for the monitor amp and speaker setup, while the Tape Outs (direct outputs from the individual tape tracks), can be used either to feed an external mixer for mixing down, or even as extra effects sends relating to the individual tracks.
Each of the six mixer channels has an Input Fader to adjust the level of the signal going through that channel, and associated with these faders are input source switches, which determine whether the incoming signal is derived from the Input jack or the Tape track. Channels 1-4 have a Foldback (pre-fader) level control, which can be sourced from either the input signal or the tape signal, depending on what you want to listen to. All six channels have a Pan control. The EQ on channels 1-4 (10kHz +/- 12dB) and Low (100Hz +/- 12dB). The manual refers to this as a parametric equaliser, but this isn't, strictly speaking, accurate, as a parametric has further controls to set the width of the band of frequencies affected by the equaliser. The Aux Send arrangement is the same on all four channels. There's only one pot per channel, despite the fact there are two Aux Sends; the pot is centre zero, so you turn it anti-clockwise to send to Aux 1 or clockwise to send to Aux 2. Obviously this means that you can't have both effects on a channel signal simultaneously. There is a switch associated with the Aux send system which selects whether the signal you are sending to your effects processor is derived from the channel (ie. input/tape signal) or the foldback buss. This means in practice that you can have effects on your monitor mix when you're doing your overdubs -- a nice touch, as most people sing better with a little reverb in the cans. Finally, the Master section has overall level controls for Aux Sends 1 and 2, Returns 1 and 2, Monitor level, and the stereo left/right output (Master Fader).
The tape deck offers nothing startlingly new in the control department, except for the fact that there is no Pause button. Pressing Record without the tape playing allows you to monitor the signal you are about to record and set its level. To record on a particular track you have to select it via one of four Rec Select switches. You can then monitor its status from flashing (record ready) to continually lit (recording). In Rehearsal mode, depressing the footswitch switches the track monitoring from the off-tape signal to the input signal, which allows you to hear how your punch-in would sound before actually committing yourself to doing it. The LED display contains the metering, and has six bar meters, four for the tape tracks and two for the Left and Right buss. The colours used are rather happy shades of golden honey and lemon, and the Rec Status lamps are quite large, so you're unlikely to miss the fact that one is flashing! There's also a cute little LED diagram of the tape, which imitates the tape travel, showing whether you're in Play mode, Fast Forward or Rewind. There's quite a bit of headroom on the meters, so you can go a couple of bars into the red (actually gold) before you get distortion.
The compact, lightweight X55 is rather attractive, it and is laid out sensibly, with the connections easily accessible and clearly labelled. The knobs, which have a rubbery surface, are smooth in action and quite slim -- just as well, as they're rather close together. The faders feel positive. ]
The X55's sound quality is very good, The use of Dolby C noise reduction means that there is none of the coarseness which can occur with dbx, especially on a bounced track.
I was pleased to note that the mixer is surprisingly quiet in use; The EQ is very pleasant and smooth -- not peaky, boomy or harsh -- and the sweep-mid controls allow for a wide range of EQ possibilities.
As is often stated, people have a habit of over-using EQ anyway.
The XR55s headphone amplifier quality is excellent. -- so often the circuit used is cheap and noisy, because it is assumed that you'll only use the headphones for doing your takes, rather than for actually checking out your sound quality.
Punch-ins are quiet and positive and are most easily managed using a remote footswitch; although you can punch in manually (as opposed to footually) by holding down Rec and hitting Play, This makes the footswitch essential for any serious work -- which begs the question: why is it optional?
The Rehearsal feature was helpful and easy to use. I liked the idea of having centre detents on the Aux and EQ controls.
Fostex have tried hard to provide a good level of basic quality and enough flexibility to let you get around most of the common restrictions. You do get insert points and three-band EQ, There are two Aux sends. On the completely positive side you get the fancy and informative LED display; Search Zero and the Rehearsal features; pitch control; a tape sync facility; and a couple of extra channels to plug your MIDI gear into. The sound quality, which is above average; both mixer noise and tape noise have been kept to a minimum. At the end of the day, no matter how many features you've got, it's the sound of the finished product that counts, and with this unit you've got more than a fighting chance of coming up with a professional demo.

Dispite speculation about the demise of analogue recording in all its forms, 4-track cassette-based multitrackers continue to be very popular.
The manual has been written with the recording newcomer in mind and includes step-by-step instructions for recording a first session .The X55 also has a few rather advanced features, such as a Rehearsal mode, which, as well as saving in setting-up time, can be a great help for those doing their first few overdubs.
