3-4e) CONSOLE OUTPUTS TO TELEPHONE LINES
Under NO circumstances should a console output be used to directly drive telephone lines. The console outputs WILL be destroyed most
likely by lightning. A telephone company approved coupler or (preferably) a telephone hybrid MUST be used. Arrakis Systems doesn‘t,
under any circumstances, warranty damage due to lightning or any telephone line transients.
3-4f) MONITOR, HEADPHONE AND CUE SYSTEMS
The monitor, headphone and cue outputs are unbalanced with Zout <50½. These outputs will drive (>600 ohm) with no difficulty. These
outputs will NOT, however, drive 8½ speakers or LO-Z headphones directly. In order to interface monitor and cue speakers to the console
external power amplifiers must be used.
The monitor and cue outputs mute electronically when activated therefore do not require external muting relays.
