Buzzaudio Elixir - Mono Mic Pre API 500 Series
£750.00 ex. vat
The elixir preamplifier module is an excellent compliment to the "fatter" sound of many modules now available in the API 500VPR Series format and has been designed to provide exceptionally low noise wide bandwidth amplification of microphone and instrument signals. The elixir will suit those who desire a recording preamplifier where just a slight amount of bass colour is added to the original signal whilst retaining full treble extension and a smooth midrange - warm, sweet, liquid - the perfect blend.
The elixir circuit design uses two BE40 True Class A amplifiers in a transformeless input arrangement followed by two newly designed BE50 True Class A high current audio buffers that drive a Lundahl LL1517 output transformer. The topology is balanced throughout with the transformer providing the balanced to balanced output conversion and common mode rejection. This set up is quite different to most single amplifier 500 series preamps and ensures excellent transient response, extended bandwidth and very good induced noise rejection.
Looking at the distortion specifications, the presence of the Lundahl* output transformer adds a subtle amount of harmonic at low frequencies thereby enhancing the bottom end but without sacrificing the wide bandwith needed for good clarity and transient response in the top end. The output configuration of the elixir results in a maximum output level of +34dBu before clipping, which means it can comfortably deliver clean audio into all analogue or digital recorders without overload.
Gain range of the microphone input is 22dB to 70dB or -2dB to 50dB with the -20dB pad selected. More than enough for ribbon microphones. The input impedance (selected with the IN Z switch) is 4000 ohms in the H position or 1200 ohms in the L position.
The instrument input on the elixir features a "bootstrapped FET" high to low impedance convertor that then feeds the elixir amplifier stages. Selection of the instrument input is automatic when a jack is inserted on the front panel input. Gain range of the instrument input is 10db less than the mic input at 12dB to 60dB. The input impedance is switchable 1,000,000 ohms or 20,000 ohms with the IN Z switch
