Samson MPL 1502 User Manual

Introduction
• Independent 3-band equalization for each channel, with 15 dB of cut or boost
for low (80 Hz) and high (10 kHz) frequencies, and 12 dB of cut or boost for
the mid-range (800 Hz) frequency.
• Constant level pan controls for placing each monophonic channel in the left-
right stereo spectrum, as well as balance controls for each stereo channel
and Aux return that allow you to blend the relative levels of stereo inputs.
• Channel inserts are provided for each of the 5 monophonic input channels,
enabling you to use outboard signal processors such as outboard
equalizers, compressor/ limiters, or noise gates in a standard “effect loop.”
• Input trims for each channel are continuously adjustable from +4 to -50 dB,
making it possible to use the MPL 1502 with a wide variety of signal sources
and outboard equipment.
• Center detents for all gain, pan, balance, and EQ controls, making it easy to
use the MPL 1502 even in low-light situations such as live performance.
• Peak input LEDs for each channel, showing you when an input signal is
overloading or near overloading (these illuminate -5 dB prior to distortion).
• The provision of 48v phantom power makes it possible to plug high-quality
condenser microphones directly into the MPL 1502, without the need for
expensive and cumbersome external power supplies.
• A seven-segment front-panel meter that allows you to view at a glance the
continuous main stereo output level.
• An independent front-panel headphone jack with dedicated volume control.
• With accessory rack ears, the MPL 1502 can be mounted in any standard
19” rack (taking six rack spaces), making it easy to integrate into any exist-
ing system.
• Last but certainly not least, affordability. The MPL 1502 has been designed
from the ground up to provide versatility and excellent sound quality at a
cost-conscious price.
