We took the circuit topology of the Sta-Level and packed it into a single width 500 module. The 500PREthree tube gain stage exhibits the same detail and depth. As with all Retro products, the feeling of themusical performance is delivered with the Retro Instruments 500PRE.
Distortion, Noise and Frequency Response of the 500PRE are outstanding; but overload characteristicsare not generally revealed by standard measurements. The 500PRE tubes gracefully limit the signal at+18 dBu. Whether you're just going for clean gain or pushing the 500PRE into overdrive, it won't eversound plastic and brittle like solid-state amplifiers can. Transient detail is unrestrained.
The Retro 500PRE doesn't sleep when you're done tracking. Use the 500PRE as a high-energy limiterduring mix-time. The 500PRE design purposely has the limiter effect of tube amplifiers. You'll love touse it as a limiter to fatten all kinds of tracks.
The Retro 500PRE works within API 500 rack power limitations. Each 500PRE consumes 160 ma ofpower, slightly above the 130 ma VPR-compliant allocation. We recommend racks with quiet linearpower supplies like the API models. When power requirements are observed, the rack and 500PRE willprovide years of reliable service.
The Retro 500PRE uses three 12AT7 tubes that are readily available as new production or new-old-stock.A user can select from a wide variety. Your unit uses the new production TAD 12AT7 and these tubesare expected to last for a very long time under the 500PRE operating conditions. We use soft-startcircuitry that minimizes stress to the tubes and power supply. The 500PRE takes less than a minute towarm up and perform.
No frills layout and simple controls make it easy to set and start recording. You can dial in up to 75 dB ofamplification. The GAIN switch in the LOW setting converts the 500PRE to a classic two-stage amplifierand can sustain +10 dBu input levels without overload. An adjustable output attenuator provides theoptimum level to all of your gear. It also allows you to overdrive without clipping downstream gear.
The 500PRE is fully transformer balanced with high-quality Cinemag transformers for low noise, highheadroom and superior audio performance.
