mic preamplifier for 500 series
key features * real Class-A discrete circuitry * Lundahl output transformer * wide frequency response * excellent transient response * very high headroom * 70dB of low noise gain for ribbon mics *
There is an overwhelming number of 500 Series mic preamps
to choose from, many of which are clones or copies of vintage
units. So, as a breath of fresh air, we present the Elixir
preamp module that stands apart from that crowd. By using
our own True Class A amplifiers and Swedish Lundahl output
transformers, we've produced a warm sweet liquid sound quality
that is unique and a useful compliment in your rack to other "harder" sounding 500 Series
Elixir has a fast transient response so it is ideal
for stringed instruments and percussion - a superb choice
for snare drum and acoustic guitars. And as with all our
preamps the noise level is as low as possible and there is plenty of gain for
ribbon microphones. The instrument jack input has a very special "bootstrap" amplifier design and really does sound huge on bass guitar.
A 41 detent Gain pot provides up to 70dB of grunt (60dB
using the Instrument input). Toggle switches select the
48V Phantom Power on/off, High or Low Mic and Instrument
input impedance (IN Z), the 20dB Pad, Phase Reverse and
Output Mute. The 1/4" jack Instrument input is automatically
selected when a jack is inserted. A four led peak meter
gives good indication of output level, but due to the
massive +34dBu output headroom, it is unlikely the Elixir will
clip before the next unit in the chain does!
The Elixir preamp module will physically fit into all
500 Series racks, but it should be noted the current draw
is 150mA, which is double that of most other 500 Series
modules. This should not be an issue with most modern
racks, but with older 500 Series racks it may mean only
one or two Elixirs should be fitted along with other modules.
If in doubt please feel free to contact
us, we are happy to help.
