Electrodyne 2501 preamp

In January 2009, Electrodyne and Pete's Place Audio teamed up to bring back the classic Electrodyne brand in 500 Series module form with the launch of the 501 discrete 2-stage studio preamp and 511 2-band inductor EQ. The two companies have come together once again to offer dual mono-channel, 19-inch rack-mounted versions of both products: the Electrodyne 2501 ($2,095.50) and 2511 ($2,300), which will be shown October 17-20 at the AES Convention in New York City's Javits Center at A-Designs Audio's stand #3130.

These two new products represent a continuing joint venture between Electrodyne and Pete's Place Audio, which will manufacture, market and sell the products.

Like the Electrodyne 501, the new 2501 is a 2-stage discrete transistor, transformer-coupled preamp with active DI based primarily on the modules found in the classic 1608 console. Each amp stage is individually optimized for peak performance using detailed Electrodyne factory engineering notes and select high performance components identical to the originals. In addition, the 2501's transformers are made by Electrodyne's original supplier to exacting factory specifications.

The preamp's active DI circuit presents a load of 6 megohms to sensitive musical instrument outputs. Furthermore, the output of the DI circuit is designed to directly connect and interact with the mic input transformer to permit an extremely broad spectrum of tonal options.

The faceplate of the Electrodyne 2501 features two sets of dual large rotary gain controls offering up to 68 dB of gain, adjustable over 50 dB in 2dB steps with two ranges via a 20dB pad switch, and two smaller output level pots infinitely adjustable from 0 (off) to +6dB over unity. Additional switches for impedance selection (50 or 200 ohms), phase reverse, +48-volt phantom power and DI (with ¼-inch input jack) are also present, as well as a clip LED on each channel that monitors all three amp stages and illuminates when any stage is 3 dB from clipping.

The new 2511 is a 2-channel, 2-band discrete transistor, reciprocal, active inductor-based equalizer based on late '60s/early '70s design technology. As with the 2501, the 2511's custom inductors and output transformer are made by Electrodyne's original provider to strict factory tolerances as small as 2 percent. This affords a consistent EQ performance and repeatability from channel to channel that was not possible in the 1960s. Smooth performance and EQ response from minimum to maximum gain at all frequencies provides unusually broad sonic and tonal options not experienced since the 1970s.

The module's faceplate sports two sets of twin large rotary EQ controls each offering ±12dB of boost and cut with four selectable frequencies per band (LF: 40, 100, 250 and 500 Hz; HF: 1.5, 3, 5 and 10 kHz). Shelving is available on all frequencies, with peaking offered at 250 and 500Hz in the LF band and 1.5, 3 and 5kHz in the HF band. An EQ in/out switch with accompanying LED on each channel rounds out the front panel feature set.

Both the 2501 and 2511 deliver a maximum output of almost +30dBm into 600 ohms paired with extremely low distortion specs, high signal-to-noise, and wide dynamic range.

The two modules use '70s NOS Electrodyne knobs from the original factory.
