500 SERIES MIXER O/P
OWNERS HANDBOOK
ABOUT THE DESIGNER:
Ocean Audio products are designed by the distinguished pro-audio designer, Malcolm Toft.
Malcolm joined Trident Studios in 1968 as it’s first recording engineer. At that time
it was the only studio in europe to have 8 track recording facilities. It soon gained a
worldwide reputation for the quality of it’s equipment and engineers.
Malcolm worked with Tony Visconti on three Tyrannosaurus Rex albums (the band later
became T-Rex). He also engineered David Bowie’s ‘Space Oddity’ album and James
Taylor’s first album. He was also a mixing engineer on the Beatles biggest selling single
‘Hey Jude’ which was recorded at Trident.
In 1971 Malcolm became manager of the studios and was tasked with finding a new
24 track console for the studios. It soon became apparent to him that they could not get
a console to the specifications and facilities that they required from any of the
manufacturers around at that time. So Malcolm convinced the studio owners that they
could build their own console. Consequently, In conjunction with the studio’s maintenance
engineer Barry Porter, he designed the Trident A Range console as it became known.
This led to the birth of Trident Audio Developments which Malcolm ran until 1988 when
he sold it to a public company. In 1992 he was asked to design a replacement for the
Trident Series 80 console which the new owners were no longer manufacturing. This
Malcolm did and he started a new company Malcolm Toft Associates Ltd (MTA).
Clients for MTA consoles include Radiohead and The Liverpool Institute of performing
arts.
Latterly he has designed the highly successful Toft ATB console range for PMI Audio.
He was made a visiting professor at Leeds College of Music in 2008

GENERAL DESCRIPTION
The Ocean Audio 500 Series Master Output module when used in conjunction with
any number of Ocean Audio Input modules, makes a powerful mixing console for the
500 Series rack system.
This two width module provides a master level control for the stereo output together
with accurate bargraph meters that also read the solo levels when activated.
It also provides master level controls and balanced output jacks for the four
auxiliary sends. There is also a solo master level control, headphone level
and output jack plus an independent control room monitor level control.
The module should be carefully slotted into the appropriate two positions of any 500
Series Rack.
By means of the ribbon cable supplied with any Ocean Audio I/P module, connect it to
the I/P module which can be located on either side of the O/P module.
These 16 way connectors can be found on either side of the module printed circuit
board. The rack can now be powered up.
The following procedures should be carried out without power applied to the
rack.
Now turn the L/R Group Master control until the bargraph displays indicate signal.
It is a good idea to put the L/R Group Master control to approximately three quarters
of it’s travel which will correspond to 0db output. The I/P module level control should
now be advanced to obtain a suitable reading on the bargraph display.
If the ‘SOLO’ master control is turned clockwise and the ‘SOLO’ button on the input is
depressed, the red LED next to the solo master control will flash and the solo signal
will be indicated on the bargraph meters.
By plugging a balanced (stereo) jack into any or all of the four ‘AUX SEND’ jacks the
auxiliary sends can be accessed. Turning the associated master level controlwill adjust
the overall level of the auxiliary send.
