Introduction, MPL 1502 System Features

Introduction

Congratulations on purchasing the Samson MPL 1502 stereo mixer! Although this unit is designed for easy operation, we suggest you first take some time to go through these pages so you can fully understand how we’ve implemented a number of unique features.

In this manual, we’ll provide you with an overview of the MPL 1502 features, followed by a guided tour of its front and rear panels. Then we’ll describe how the MPL 1502 should be connected to your existing equipment (including wiring diagrams) and talk about the important topics of gain structure and grounding techniques. Next, we’ll cover a number of specific MPL 1502 features (such as panning, equalization, auxiliary sends and returns, and channel inserts) in detail. Finally, we’ll wrap things up with a series of applications notes describing how you can use the MPL 1502 for both live performance and recording. You’ll also find a warranty card enclosed—please don’t forget to fill it out and mail it so that you can receive online technical support and so we can send you updated information about other Samson products in the future.

SPECIAL NOTE: Should your unit ever require servicing, a Return Authorization number (RA) is necessary. Without this number, the unit will not be accepted. Please call Samson at 1-800-372-6766 for a Return Authorization number prior to shipping your unit. Please retain the original packing materials and, if possible, return the unit in its original carton and packing materials.

MPL 1502 System Features

“MPL” stands for “Microphone/Program/Line” and the name describes the broad range of signals which can be handled by this powerful stereo mixer. In fact, the compact design of the MPL 1502 belies an extraordinary versatility. Add excel- lent sound quality to the equation, and you’ve got a product which is equally useful as a live performance mixer, keyboard submixer, or even for simple recording purposes (you’ll find descriptions of each of these applications at the conclusion of this manual). Here are some of the MPL 1502’s main features:

•Fifteen input channels, including five stereo channels. The five monophonic channels provide electronically balanced inputs that can be used for micro- phone or line-level input, and the five stereo channels are ideal for line-level sources such as outboard signal processors; CD players; tape or cassette recorders; stereo drum machines; and keyboards and MIDI tone modules.

•An electronically balanced main stereo output for connection to a power amplifier.

•A dedicated tape input/output that allows direct recording of a live performance and playback of prerecorded material.

•Two auxiliary sends and two stereo auxiliary returns (which can be used as four monophonic returns). Both sends are post-fader and post-equalizer.
