TRUE Systems Precision 8 Review: Eight Channels of Transparent Preamplification

TRUE Systems is an interesting company, and its products occupy an interesting place in the history of professional recording equipment. For years, the company manufactured a range of exceptionally clean microphone preamplifiers that never seemed to attract quite the attention they deserved.

The original preamplifier line is no longer being manufactured, although the TRUE Systems name and its engineering legacy remain associated with Cloud Microphones. One of its most interesting products is the Precision 8, an eight-channel microphone preamplifier that squeezes a surprising amount of functionality into a single rack space. More importantly, it sounds excellent.

I’ve always thought of the TRUE preamps as something like a poor man’s GML. That’s not an insult. George Massenburg’s preamps represent a philosophy of getting the signal into the recording system as accurately as possible without imposing an identifiable sonic signature. The Precision 8 follows much the same philosophy, at a more approachable price.

Eight channels in one rack space

Eight microphone preamplifiers in a single rack space is quite an accomplishment, particularly considering the performance and features offered. Each channel has a continuously variable gain control, individually switched 48-volt phantom power, polarity reversal and LED level metering. There’s up to 64 dB of microphone gain available. The original Precision 8 also has an internal linear power supply, making the packaging even more impressive.

Unusually flexible connections

The rear panel offers eight balanced XLR microphone inputs, with channels 7 and 8 using combination connectors that also accept quarter-inch instrument plugs. Those two channels offer discrete FET direct inputs, allowing guitars, basses and other instruments to be connected without an external DI box.

There are eight individual balanced quarter-inch TRS outputs, along with a DB25 connector carrying eight channels of balanced analog audio. Both output sets can operate simultaneously, making it easy to feed a recording interface and another destination. They are not independently transformer-isolated outputs, however, so this is not a substitute for a dedicated isolated microphone splitter.

Yes, it has Mid-Side decoding

One unusual feature is built-in Mid-Side stereo decoding on channels 1 and 2. Mid-Side recording combines a forward-facing Mid microphone with a sideways-facing figure-eight Side microphone. The Precision 8 can decode those signals internally into a conventional stereo pair. The two gain controls influence the stereo balance and width, although their interaction means this isn’t quite like having a separate dedicated width control. It’s a clever feature for acoustic ensembles, classical music and location recording.

What does the TRUE Systems Precision 8 sound like?

It doesn’t really sound like anything. And I mean that as a compliment.

There are plenty of microphone preamplifiers that people buy specifically for character: transformer saturation, harmonic distortion, softened transients, a thickened bottom end or some other identifiable coloration. Sometimes that’s exactly what you want. The Precision 8 isn’t that kind of preamp.

It’s clean, quiet and accurate. It doesn’t seem particularly interested in making your microphone sound bigger, warmer, thicker or more expensive. It simply amplifies the signal. What you hear is primarily the microphone, the source and the room rather than the electronics.

That’s why I think the GML comparison is appropriate. I’m not claiming technical equivalence or a controlled shootout. They simply share a philosophy: get out of the way.

Why transparent preamps matter

I own and appreciate plenty of colorful recording equipment. But if I’m recording a particularly good acoustic instrument with a carefully selected microphone, I may not want the preamp contributing anything recognizable. The same goes for piano, percussion, orchestral sessions and location recording. A clean preamp gives you a useful reference point. You can add coloration later; removing coloration already recorded is another matter.

The TRUE Systems family

TRUE Systems also offered the two-channel P2 Analog, the P-Solo and P-Solo Ribbon, and a 500-series model, the pT2-500. The common theme was low noise, headroom and transparent reproduction. These were serious professional tools offering particularly good value.

Buying a used Precision 8

Since the original Precision 8 is discontinued, the used market is the place to look. Because the brand never developed quite the same cult following as some vintage preamps, a good example can be excellent value.

As with any older electronic device, check all eight channels, gain controls, phantom power, meters, switches, instrument inputs and the Mid-Side function. Also distinguish the original Precision 8 from the later Precision 8i; they aren’t identical, including in their power supply arrangements.

A good microphone preamplifier doesn’t stop being good because it’s twenty years old.

Final thoughts

The TRUE Systems Precision 8 doesn’t have enormous transformers, glowing tubes or a legendary vintage console pedigree. What it does have is eight channels of extremely clean microphone amplification, useful metering, flexible analog outputs, two instrument inputs and Mid-Side decoding, all in a single rack space.

It’s quiet, accurate, robust and refreshingly uninterested in imposing its personality on your recordings. If you’re looking for a preamp that adds color, look elsewhere. But if you want to hear the microphone and instrument rather than the preamplifier, the Precision 8 is an excellent choice. At a reasonable used price, eight channels of this quality in one rack space is still a compelling proposition.
