PM - 100 Introduction

The Formula Sound PM-100 mixer is essentially the successor to our award winning PM-80 and

PM-90 mixers.

We believe that the experience we have gained over the past 21 years of producing the PM-80 and

PM-90 has produced a mixer that is equal to the challenges of the new millennium. We have

incorporated new features and innovations that have been in our file of wish lists from operators

around the world. We have tried to provide a tool that can be individual to the operator, We can

provide advice on how to achieve the best performance out of this equipment but when it comes to

mixing it becomes personal taste so we have provided the tools to do the job with choices where

possible. We believe that the equipment should not restrict the creative talent but help it.

General Description

The PM-100 is a compact modular production mixing system which combines exemplary technical

performance with the highest standards of mechanical engineering.

The system is totally modular each module being complete in itself. The connections to the modules

are via a flexible 34 way ribbon cable and gold plated computer grade connectors.

The chassis contains no electronics therefore upgrading to a larger chassis size is quite straight-

forward.

There are only three types of module, a universal input channel module, a blank module to fill unused

space in the chassis and the output module containing all the mixing, monitoring, and output

electronics.

The mixer is factory assembled with the output module towards the right hand end of the chassis and

the input modules to the left. But in fact modules may be positioned in any format required.

Specific layouts may be ordered or engineers can easily change layouts to suit individual

requirements. Blank modules where fitted may be easily replaced by input modules at a later date if

required.

The chassis is available in 3 standard sizes, 4 channel, 8 channel (19" rack mount) and 12 channel.

Larger sizes can be offered to special order.

Power Supply

The mixer requires an external power supply unit providing +/-17.5V for the audio electronics and 12V

for the working illumination socket.

A suitable power supply unit, the PSU5, is available. This unit is designed to be surface mounted

remotely from the mixer and features slow rise time characteristics to minimise turn on thrumps.

The unit is internally switchable to operate from 220-240V AC or 110-120V AC. Check that the

voltage selector switch is correctly set for the mains voltage available before connecting power.

Damage may result if the unit is connected to the wrong supply voltage.

It is important from a performance and safety aspect that the power supply is connected to a reliable

and suitable earth . Remember that this earth connection may also be providing the earth for input

sources connected to the mixer, turntables, microphones etc. For safe and reliable operation

adequate ventilation must be provided. Do not cover the power supply .

Mount the power supply in a suitable location bearing in mind that the captive connecting lead length

is 1.5 meters. Connect the mixer to the power supply ensuring that the connector is fully mated and

the securing screws fastened. (Do not over tighten the securing screws).
