Using Styroflex and tantalum capacitors, the designers were able to fit all three 1073 discrete component Class A preamplifier gain stages in 1U of an API 500 Series lunchbox module. The preamplifier supports selectable HI-LO minimum balanced and floating input impedances that accommodate a range of microphone types including vintage ribbons. You can also switch the module into line mode to re-amplify pre-recorded tracks and add color to a mix. Plugging in a mono 1/4" input into the DI port on the front of the unit automatically switches the module from MIC to DI mode. A discrete component Class A 3rd order 80 Hz high-pass filter with an 18 dB per octave slope has been added for recording sources without the effects of low-frequency coloration. An output control knob is included to prevent overloading the preamplifier.
The unit is powered by a +24V slow turn on power regulator that takes approximately 20 seconds to reach full voltage. This design improves the overall operation of your lunchbox PSU and makes the unit independent from the other modules in the lunchbox. To achieve the classic feel of the original 1073, the unit is constructed with Marconi-style knobs and vintage engraved pushbuttons.
The Heritage Audio HA73jr 500 Series microphone preamplifier brings a huge does of vintage vibe straight to your rack. It's based on the iconic 1073, amplifying any microphone or instrument clearly and vibrantly. And because there are separate input and output gain controls, you can drive the HA73jr's input to get rich, saturated sound like you would on a vintage console. Factor in an incredible 80dB of gain, and you've got a preamp that's ready to bring out the best of any microphone - condenser, dynamic, or ribbon. Said another way, it's difficult to get a bad sound out of the Heritage Audio HA73jr.
Add rich transformer saturation to any source The Heritage Audio HA73jr has Carnhill input and output transformers, ready to add a touch of glow to any sound source - mic, line, or even DI instruments. The DI circuit is ahead of the mic input transformer, perfect for adding some hair to DI bass signals on the way in. Best of all, the HA73jr preamp module has separate input and output gain controls. That lets you crank the input gain to get more transformer color, without overloading the output stage.
