INSTALLATION AND SETTING PROCEDURES (HARDWARE)
8.12. Preamp Matrix Panel Connection
8.12.1. Input equipment connections
Connect microphones or other music players to the audio inputs using 2-core shielded cables or single core
shielded cables.
Eight Input channels (1 through 8) are provided for the audio inputs. Use 2-core shielded cables for connection
to Audio inputs 1 through 4, and single core shielded cables to Audio inputs 5 through 8.
If the music player has a control output, connect the control output to the control input of the Preamplier matrix
panel.
The input signal levels of Audio inputs 1 through 4 of the Preamplier matrix panel can be selected by the front-
mounted input level setting switches.
Also, the front-mounted volume controls allow the individual volume adjustment of Audio inputs 1 through 8.
Make the input-related settings such as purpose of use and audio source type using the VX-3000 Setting
Software. (See the separate Setting Software Instructions, "Unit Conguration Settings.")
