PRODUCT REGISTRATION Malcolm joined 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 Ocean Audio products are warranted for two years after first purchase against faulty worldwide reputation for the quality of it’s equipment and engineers. manufacture or component failure.

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 AUX 1-4 MASTER depressed, the red LED next to the solo master control will flash and the solo signal LEVEL CONTROLS will be indicated on the bargraph meters.
