Introduction - Design - Installation

1. INTRODUCTION

In purchasing the new PM8, you have acquired a multi-channel passive summing mixer of high
class that meets the demands of the home and professional studio. This sturdy 2RU allows for
up to 8 channels of audio to be passively mixed down to a stereo output pair. Each input chan-
nel features its own pan, mute, and rotary volume attenuator control. Eight professional combo
connector inputs (XLR & ¼” TS) and three balanced XLR stereo output pairs can be found on
the rear panel. A 25pin D-SUB connector is also available for direct connection from compati-
ble Tascam and Digidesign systems.

2. THE DESIGN

2.1 High quality components and design

The philosophy behind SM Pro Audio products guarantees a no-compromise circuit design and
fault-tolerant component selection. All SM Pro Audio products go through a rigorous planning and
production procedure from start to finish.

2.2 Inputs and outputs

All inputs and outputs are secured firmly to the exterior chassis housing thus ensuring robust qual-
ity and confidence under all conditions.

3. INSTALLATION

Your SM Pro Audio PM8 was carefully packed in the factory and the packaging was designed to
protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the
packaging and its contents for any signs of physical damage, which may have occurred in transit.

* If you happen to receive a damaged unit, please notify your dealer and the shipping company
immediately.

3.1 What’s included in the box

You should have the following included inside your shipping box:
- 1 x PM8 Multi-channel passive summing mixer
- 1 x Power cable
- 1 x Operational user guide (the one you are reading!)

3.2 Rack-mount installation

The SM Pro Audio PM8 can be used stand alone on your desktop, however it is best installed into
“two” standard 19” compatible audio rack-mount unit spaces.

Please remove all cables (including power) before installing the PM8 into your audio rack. 

Sturdy rack mounting ears are present on each side of the PM8’s front panel. Simply mount the
PM8 into an available 2 rack-space position and secure with rack-mount bolts/screws.

* Note: Please take into consideration ventilation of your equipment. A well-ventilated equip-
ment rack will ensure optimum operation and longevity of your equipment. It’s often a good idea
to leave 1 free rack-bay position between your equipment to allow.
