High Performance Microphone Inputs
•
Maximum of 66 dB of gain per input.
•
Premium Lundahl input transformers provide
superior sonic quality and freedom from
interference problems.
•
Sealed, conductive plastic potentiometers for
long-life, reliable gain adjustment.
•
Phantom power, selectable between 48-volts
and 15-volts.
•
High-pass filters with 80 or 160 Hz corner
frequencies, 6 dB per octave. Filters are
inserted prior to any active circuitry for extra
high headroom.
Audio Performance
•
Dynamic range exceeding 110 dB.
•
10 Hz to 50 kHz audio bandwidth.
•
Exceptionally low distortion characteristics.
•
Discrete 6-transistor balanced output drivers
provide robust drive for long cable runs.
Headphone Monitoring
•
High current headphone monitor circuit enables
monitoring of program audio or external stereo
tape return audio.
•
Headphone level control and peak-indicator.
Level Metering
•
Sunlight-readable seven-segment GaN LED
output meters.

General Description
Features
location, and live music engineers value the
compact size and ability to withstand extremes in
the field. The MP-2 combines rugged mechanical
and electronic construction, compact size, and high-
quality components. The MP-2 allows no-
compromise performance for any application.
•
Three-position LED brightness switch.
•
Two-color LEDs per input channel indicate
clipping and limiter activity.
M/S Stereo Matrix
•
MS stereo decoder assigned to headphones, or
headphones and outputs.
•
Allows for flexible post-production processing.
Audio Limiters
•
"Unclippable" input peak limiters via two-stage
opto-isolator circuit with adjustable limiter
threshold (per input).
•
Dual mono or linked stereo limiter operation.
Flexible Powering
•
Internal battery-power from two AA batteries
with easy access battery compartment.
•
Chassis-isolated 5 to 18 VDC input for easy
external DC powering.
•
Power LED indicates low battery power.
Trouble Free Design
•
High strength, extruded aluminum chassis with
protective metal end panels withstands
punishing field conditions.
•
All-metal connectors solidly mounted to the
chassis for durability and RF immunity.
•
Free from "Pin 1" grounding problems.
•
RF filtering on all inputs and outputs.
