By passing the savings straight into the end users´ pockets, Heritage Audio releases the most affordable outboard preamps and equalizers in its class up to date. Key components to obtain a true vintage sound are indeed maintained, like the industry standard Carnhill transformers, hand wound in St Ives, England. Manufactured in the same Spanish facilities as the rest of the HA line of products, the HA73EQ Elite rack mountable mic preamp equalizer presents the complete classic recording channel that, for generations, has been regarded for its rich, musical qualities and its ability to dramatically improve the sound of almost any source. No ´73 equalizer will present the correct equalization curves without high quality capacitors and, most importantly, correct Vinkor type pot core inductors. More than often this type of products have these expensive inductors replaced with generic ferrite core ones or, even worst, the mid band dual inductor replaced with a single one.
Never in Heritage Audio products!! As the impact of replacing these to the eq curves is dramatic, leading to incorrect curve´s shapes and high frequency phase distortion which in no way honor the design. The HA73EQ Elite employs WIMA 5% capacitors in the EQ section as well as 3 correct vintage type Vinkor pot core inductors so the eq curves are virtually undistinguishable from the handmade equalizers in the HA line.
Customers can expect the same sonic quality and feel they have come to appreciate from Heritage Audio. The HA73EQs preamp section features gain, output trim, -20db pad, polarity reverse, a high pass filter, and +48v phantom power. The HA73EQs EQ section features a high shelving EQ, midrange EQ, low shelving EQ, a variable high pass filter, and EQ Bypass. The HA73EQ comes housed in a rugged 1RU British steel and aluminum chassis and utilizes an external power supply for low noise operation.
