Like many successful small, specialist companies, Formula Sound was created from the vision and experience of its founders. The vision, which has since become both reality and the company's mission statement was to bring professional studio or broadcast quality sound equipment into the leisure arena.
The
experience of the founder and MD Tony Cockell proved invaluable and has provided
a sturdy base from which to grow and to develop new products. Tony spent his
earlier years designing and building sound systems, working as a recording engineer
and touring as a trouble shooter with internationally acclaimed music groups,
and was himself a semi-pro musician. He knew what sound professionals needed
and at what quality level to provide it.

In response
to noise level regulations and demands from the trade for a level control
unit which will work with any audio system, Formula Sound have designed
the AVC2. The AVC2 performs as an intelligent volume control and in operation is very simple. If the average operating level is kept below the internally set threshold, the AVC2 has no effect. If the average programme level exceeds the threshold the unit will reduce its output level. The level is reduced in discreet steps indicated by the l.e.d. bar graph meter on the front panel of the unit. The action of the AVC2 is to fade between these steps and is almost undetectable in use. The more one tries to increase the volume, the more the AVC2 will decrease it so that the system will barely change in perceived level. If driven to maximum attenuation, the output level will be reduced by more than the increase in input level. The mixer or pre amp feeding the AVC2 will probably be clipping, but the system will actually be at a lower than normal level. A clip indicator is provided to show when the input stage of the AVC2 is being over driven. Reducing the input level will gently release the attenuation provided by the AVC2. |

PM-100 A Modular Professional Production Mixing System Innovative Features There is only one universal input module which has been cleverly designed to accept input sources of virtually any type. A rapid action lever switch on the front panel selects between 2 sources. 2 independent headphone monitoring sections. VCA controlled crossfader and contour control. Stereo inserts provided at either end of the crossfader to allow the connection of external filters, processors, etc. Priority input to help comply with fire regulations. The master module can be placed in any position in the mixer - right, left, centre, etc to suit the individual operator. The PM-100 is a creative tool designed to give complete flexibility for both the operator and the installer. The facilities it offers are extensive whilst still being easy to use. For use in discotheques, clubs, broadcast and production studios, audiovisual presentations and any other situation where a combination of sources need to be controlled. The mixer is designed to give exemplary technical performance and is built to the highest standards of mechanical engineering. Three different chassis sizes house a master module and up to 4, 8 (19" rack mounting) or 12 input or blank modules. Integral switch illumination shows operators at a glance the status of various functions. Faders are easy to replace due to the use of plugs and sockets. The connections to the modules are via a flexible ribbon cable featuring gold plated connectors. The further use of gold plated connectors throughout the mixer ensures maximum reliability. Alps pots and faders are used throughout the mixer. |

The
FSM-400 A compact 4 channel fixed format mixer The FSM-400 is a fixed format mixer designed for the professional DJ or small installation. Available in 2 sizes - Standard or with 19" rack mount front.
7 stereo inputs, 3
of which may be selected to RIAA Formula Sound are recognised as one of the leading manufacturers of audio equipment and the FSM-400 is built to their usual high standards of construction and audio quality. Although the FSM-400 is a fixed format design the use of individual circuit cards per channel improve reliability and aid servicing should the need arise. |

The FSM-400 is primarily aimed at the professional DJ but will also be used in smaller installations where a four channel mixer with each channel switchable to two inputs can be utilised. Channel
1 is switchable between low impedance microphone and stereo line inputs.
Phantom power is available for microphones (internal selection). Three band equalisation is fitted to all inputs. The range is +5dB to -20dB. The amount of large cut eliminates the need for frequency cut switches and is available on all channels allowing creative mixing. Channels 2 to 4 have internal jumpers to provide 2 gain settings per input. The gain range is - normal ±15dB or low setting +2dB to -19dB. Push button switches are used for input selection, PFL (pre fade listen) routing etc. and a smooth 60mm fader, which is arranged to eliminate the ingress of dirt, complete the channel controls. The output section provides plenty of facilities to cope with most applications. It includes a new design of crossfade circuitry that places less demand on the fader to ensure exemplary attenuation and extended life. A punch button facility is also included. Illuminated push buttons, led meters and indicators are fitted throughout to provide the operator with good visual indication of the mixer status. Unlike the majority of fixed format mixers on the market all connectors are fitted to the back face which allows unrestricted access when the mixer is fitted through a work top or console. |

The FSM-600 The FSM-600 is a compact
fixed format stereo production mixer. The design allows the unit to accept
two microphone inputs and ten stereo music inputs. Unlike the majority of fixed format mixers on the market all connectors are fitted to the back face which allows unrestricted access when the mixer is fitted through a work top or in a rack. Although the FSM-600 is a fixed format design the use of individual circuit cards per channel improve reliability and aid servicing should the need arise. Construction and audio quality are to Formula Sounds usual highest standards. Power The mixer features a fully regulated internal power supply that is designed to operate on 220-240Vac or 110-120Vac. The selection is by an internal switch mounted on the power supply circuit board and is accessed by removing the front cover. |
