CAPI VP312DI

CAPI VP312DI is a pre-amp for the 500 series, manufactured by CAPI.

Official description
Just like the VP312, the VP312 DI is a clone of the original, vintage API 312. Except with the addition of a very versatile modular direct input. For more information on the preamp section of the VP312DI check out my page for the VP312.

The VP312DI has a modular DI format with a variety of sound options, both active and transformer based options are available.

DI Features


 * The VP312 automatically switches to DI mode when a 1/4TS connector is plugged into the Hi-Z input.
 * Option to switch between the the default DI circuit (see "DI options below') and an alternate 'Bo Hanson' style active DI which bypasses the modular DI circuit and the 2622 input transformer
 * When switched to "Bo mode" or "Post 2622" mode you have a -10db pad.
 * When switched switched to Post 2622 with the -10db pad engaged you can also engage a low pass filter which is known as "Jaco Mode"

Preamp Features


 * 60dB of gain provided by a 2520 style opamp, I regularily stock the GAR2520, GAR1731, and the SL2520 Red Dot.
 * -20dB Pad switch, polarity switch, and mute switch.
 * Fast drain 48V Phantom power.
 * Output attenuator which allows you to drive the opamp and 2503 output transformer HARD and attenuate back down to digital safe levels (this is something rarely implemented on Api style preamps, and makes for a huge variety of tones).

DI Options
 * "FET 1" Active FET based active DI. A nice aggressive tone for bass.  Included in the base price.
 * "IC1" Active Opamp based DI. Super clean sounding, good if you want minimal color.  Also available at the base price
 * Jensen JT-DB-EPC. A great sounding transformer.  Special order, contact me for a quote.
 * Cinemag CM-DBXPC. Another great sounding transformer.   Also a special order, contact me for a quote.
 * Pikatron ÜP3096M. An inexpensive but very nice sounding transformer, add $30 to the base price.
