Revox PR99

An analog multitrack with no specs is a recorder you can’t trust — or fix.

The Revox PR99 is an analog multitrack recorder with no published technical specifications. Its function is limited to basic tape-based multitrack recording and playback — but without documented parameters, alignment, or service history, it resists reliable use or evaluation.

    What it is

    It is an analog multitrack recorder — nothing more, nothing less.

  2. 1:54
    What we don’t know

    No technical specifications exist — not speed, not track count, not head type.

  3. 2:57
    What it’s called

    It is also called 'pr99' or 'pr 99' — alternate names only, no functional difference stated.

  4. 5:12
    What you can’t do

    You cannot verify its performance, calibrate it, or compare it to anything else.

Worth your time?

No. The brief is enough.

The written brief1 min read

What it is and what it was built for

The Revox PR99 is an analog multitrack recorder. It was built for recording multiple audio sources onto magnetic tape in a studio or project environment.

How it works, in terms a player would use

It records and plays back multiple audio tracks on magnetic tape. It has transport controls, level meters, and input/output jacks. No technical specifications are available to confirm tape speed, track count, or head configuration.

What it does better than anything else

Nothing is established in the sources that it does better than any other device — no comparative claims, no user testimonials, no recorded output examples, no design advantages cited.

What it does badly

It offers no verifiable technical specifications, so calibration, alignment, noise floor, frequency response, or headroom cannot be assessed or adjusted reliably.

What people made with it

No recordings, artists, albums, or projects made with the Revox PR99 are mentioned in the source material.

Who should use it, and who should not

Only someone who already has one, understands its undocumented operation, and accepts irreversible signal degradation without recourse to alignment or maintenance data. Not for beginners, restorers, or anyone needing reliability.

Is it worth your time

It is not worth your time unless you already own one and need a functional analog multitrack with no documentation, no service support, and no known signal-path details.

Revox B77RevoxThe Revox B77 is an analog multitrack tape recorder built for studio and project recording. It supports 3 3/4, 7 1/2, and 15 ips tape speeds—but the 15 ips setting is obsolete for digital use. Units from 1980 remain fully functional. It is mechanically robust and quieter than UHER models. Its meter is breakable and irreplaceable. It offers no digital functionality. It is worth your time only if you need durable, low-noise analog multitrack operation—and can maintain it yourself.

Revox A77RevoxThe Revox A77 is an analog multitrack tape recorder. Users deploy it to replay and digitise vintage tape — especially 1980s band mixes. It is robust and simple to operate, more so than the B77 or G36. But it trades mechanical precision and low-noise playback for that durability. It does not record multitrack. It does not edit. It plays — and keeps playing.

ATC SCM100ATCThe ATC SCM100ASL Pro is an active studio monitor. No technical specifications are available. It requires no external amplifier. Its performance boundaries are undocumented.

API 3124+APIThe API 3124+ is a 1U, 4-channel analog microphone preamplifier using the 2520 op-amp and classic console circuit. Each channel has gain, polarity, phantom power, 20 dB pad, mic/line selection, and a VU meter. It accepts XLR inputs at the rear and unbalanced 1/4" inputs at the front. It delivers high headroom and consistent colour across all four channels — but offers no impedance control, channel linking, or digital integration.
