1073LB – Everyone’s favourite preamp, with 500 series convenience
Designed and manufactured in England, the 1073LB uses the same architecture as the original 1073® preamplifier, conveniently packed into a single 500 series module. This compact design uses matched components and original hand-wound transformers to produce the world-famous 1073 sound.
Class A Design
Packing the classic 1073® into a 500 series module was no small feat! The 1073 class-A circuit design is faithfully maintained in the 1073LB.
Classic Gain Control
The classic 5dB stepped Elma switch delivers accurate gain staging throughout 1073’s high output gain range. This unique layout means there is no need for a mic/line switch; the pot itself selects the correct preamp and input.
Unique Gain Staging
Three different gain stages, provided by two independent transistor-based preamplifiers, provide gain for any line input or microphone signal.
High Output – Harmonic Saturation
The 1073LB combines multiple gain stages, meaning the 1073LB preamp can deliver up to 80dB of microphone gain; this brings out the musical drive and harmonic saturation that the 1073® is famous for.
Phase Invert
The 180-degree phase invert feature is handy in multi-microphone setups with multiple preamps, ideal for top and bottom snare micing.
