Following the success of the 1073/500 module, the ’73 JR is a mic preamp in a single 500 series slot with some added features that will cover all the recording needs for engineers and musicians that donÃ?´t find the need to track with EQ. Employing only discrete circuitry and conventional components, the ’73 junior is a faithful 3 stage all class A 1073 preamp. Styroflex and tantalum capacitors have been used throughout. No corners were cut. A useful all discrete class A hi pass filter has been added, essential for recording everything with the exception of probably kick drum and bass. The Line mode allows for reamping of prerecorded tracks and itÃ?´s perfect for adding some class A color to lifeless recordings. The smart switched DI (automatically switches from MIC to DI mode when inserting a MONO Ã?¼ jack ) is an all discrete class A JFET circuit ahead of the MIC transformer, so all the juice is there. Finally, special care has been taken with power handling, implementing internal +24v slow turn on regulation (about 20 seconds to reach full voltage ).This makes your lunchbox PSU healthier and makes the 73JR independent of the rest of the slots.80dB Class A Microphone preamplifierHI-LO selectable minimum input impedance, balanced and floatingHigh gain positions show a higher impedance, ideal for old ribbon mics50Db Class A Line preamplifier, bridging input impedance, balanced and floatingAll discrete Class A Ultra High Impedance J-Fet Direct Input on a high quality Neutrik JackClass A single ended, 2N3055 driven, high headroom output stagePAD: 20dB Mic input attenuation ahead of the input transformer to avoid overloading itHI PASS FILTER: Active all discrete Class A 3rd order Bessel, 80Hz Hi Pass Filter 18dB/octave slopeOUTPUT control to allow overloading of the preampInternal slow turn-on +24v power supply for lower inrush current, which improves your lunchbox performanceCarnhill Input and Output transformers3 gain stage, genuine modular card construction.
