5.0 APPLICATIONS

5.0 APPLICATIONS

The majority of mixing consoles, even quite expensive models offer only 2 or possibly 3 monitoring inputs. So if you want to simultaneously connect a CD player, DAT machine, stereo cassette deck, 2 track analogue tape machine etc. you will have to use up input channels. These are often already used for tape returns or for FX so some repatching and gain adjustment will necessary in order to replay these sources.

The SPX20 has been designed to extend the number of monitor inputs and to offer some extra facilities not found on budget priced consoles. The SPX20 is intended to be used in one of two ways -

5.1AS THE MAIN MONITOR CONTROLLER

In this application the SPX20 is used as the control centre for selecting sources and controlling levels in the monitors. Although this requires the SPX20 to mounted in a readily accessible place it does offer a number of advantages -

The two separate outputs with on-off switching and level controls can be used to drive different types of monitor speakers.

Alternatively one output can be used for the control room monitors and the other provide a studio room feed.

The monitoring system benefits from the added protection of the delayed power-on and rapid power-off switching included in the SPX20.

A number of playback sources with different output levels can be balanced to provide a consistent listening level across all the inputs.

The TAPE RECORD output allows a stereo recorder to be connected to record a rough mix whilst laying down tracks.
