tion for broadcast radio, internet radio, podcasting, and church applications. Digilink-Xtreme (Advanced ARC console mode) is provid-
ed under the Arrakis ‘Xtreme Solutions’ program which includes software, phone training, phone & email support, and software

The ARC-15 console is designed to be very easy to use. The two sets of VU meters follow the Program and Audition buses.
The single input source per channel reduces operator errors by eliminating the accidental selection of a wrong A/B source
input. The phone system is very easy tp use for off line talking to the caller as well as supporting a Live call in show or Off-
line contest call application.

Channels one is a dedicated mono microphone channel for the console operator.
CHANNEL ON AND OFF
To turn a channel on, simply push the red ON switch at the bottom of the fader. When the channel is on, the switch will be lighted. To
turn the channel off, simply push the red ON button again.
CHANNEL ON AND OFF LOGIC
Channels One and Two are assumed to be located in the control room and therefore do not require remote channel on/off logic.
PROGRAM AND AUDITION BUS ASSIGNMENT
The green PGM and AUD buttons above the slide fader assign the channel to either (or both) of the main audio mixing buses: Program
& Audition. Push the button once to light the button and assign it to the bus. Push the lighted button again to unassign the channel
from the bus.
TALKBACK
Talkback is a simple 2 way intercom system to communicate with another studio such as an Announce booth, Interview room, News
room, or Production studio.
The ARC-15 has an audio output from the control room microphone that can be connected into a console in another studio. The ARC-
15 has an audio input into the cue system for the other studio to talk to the ARC-15 console.
To activate talkback, simply cick on the red ‘Talk’ switch. To exit the talkback mode, click on the ‘Talk’ button again.

be either mono mic level or stereo line level channels. The selection is by internal jumpers on the individual chan-
nels. The console can therefore support just a single mic for the console operator or a talk studio with a host and
three guests.
CHANNEL ON AND OFF
