Description
The
LavryBlue microphone preamplifiers have been designed to provide
very clean and transparent sonic performance at a reasonable price.
The LavryBlue chassis can accommodate 2 or 4 channels of mic pre’s,
the typical 2X2 configuration (2A2D) can be expanded to include
2MicPre. If you already own a LavryBlue chassis this module takes
2 spaces. Plug and Play with the installation kit.
The MicPre
provides state of the art noise performance that accommodates
even the weakest microphone signals , and a wide input range for
the strongest mic signals. Ultra-low distortions across the complete
audio frequency band insure maximum signal transparency at all
gain settings.
The unit is
designed to yield a superior dynamic range even for high source
resistance microphones. The transformer free input provides pure
and transparent bass, yet it features state of the art in common
mode rejection (for elimination of hum and interference pickup)
exceeding transformer based units. Phantom power per channel is
ultra- low noise double shunt regulated for minimum noise and
channel separation.
Each channel
accommodates up to 21-70dB of gain in 1dB steps. The precision
gain setting is solid and reliable (not based on the use of archaic
rotary switch technology). Included is a 10dB pad for lower voltage
analog interfaces. Activating the pad yields 11-60dB gain.
Outside, the
no-nonsense controls are extremely user-friendly. Each channel
is equipped with a 2-digit gain setting display and up/down switch.
The last gain settings are stored and will reappear at next use.
A Gain Pad switch (per stereo pair) changes the gain range from
21-70dB to 11-60dB, for higher level inputs.
Each
stereo pair has a microphone selection switch (Condenser, Dynamic
or Ribbon), for microphone load optimization. Setting to “condenser”
activates the phantom power. Internal jumpers allow change from
balanced to unbalanced outputs, and for disabling of the phantom
for powered vintage mics.
