The volume control input and output have 3.5 mm stereo male and female connectors providing immediate connectivity with most computers and laptops, MP3 players and game stations. A converter cable converting 2 x RCA to 3.5 mm stereo (female) is needed for audio equipment with RCA outputs. A converter cable converting 3.5 mm stereo (male) to 2 x XLR (male) is needed to use 9000A Stereo Volume Control with Genelec monitor loudspeakers having XLR input. These cables can be obtained from an authorized Genelec dealer. The connecting cable on 9000A is Y-shaped. After 1 meter (3 ft 3″) from the control knob the single cable splits into two 1 meter (3 ft 3″) cables, one for audio input, one for audio output.
