Modular Advanced Radio Console (MARC)
The MARC-15 modular analog console comes in a single 15 channel mainframe size with a wide variety of input and option module
configurations. The console supports two phone modules for use with external hybrids. All switches are LED illuminated and ICs
are socketed (not surface mount) for reliability. Machine source control is by isolated reed relays. The meter panel hinges up
and back for access to I/O connectors and input trimpots. All I/O is by RJ45 connectors and ten foot wiring is supplied with
RJ45 at one end and unterminated at the other end (an expensive option in competing products). The MARC-15 is a very low pro-
file, attractive, tabletop design that is flexible, easy to install, reliable, and ideal for any on air or production Radio application.
Three stereo Program output mixes (with mono mixdowns) plus Monitor, Headphone, and Cue systems
15 channel modular mainframe supports many types of input modules (all with LED illumination)

Digilink-Xtreme Software for Hard Disk Automation ($100/month)
For the ultimate in Automation, Digilink-Xtreme software (optional) provides complete hard disk based automation features for the PC
USB module in the MARC-15 console. Unlike standard Xtreme for satellite automation which includes the ‘Bridge’ routing switcher,
Xtreme for the MARC-15 uses the console for audio playback & recording. Where satellite based automation selects between multiple
satellite audio feeds, Xtreme for the MARC-15 plays entirely from audio files stored on the hard disk and does not control external
sources at all. This makes Xtreme for the MARC-15 ideal for hard file based automation for broadcast or internet radio applications.
The power of this system lies in the merging of console and PC into a single integrated play and record studio. The ability to use the
console to mix and control recording to the PC makes this system perfect for producing recorded programs. Use the MARC-15 console
to produce your live air segments and then go fully automated for the rest of the day or week.
the Xtreme Solutions Program provides software, phone training, phone & email support, and software upgrades
No contract required, cancel at any time if the Solutions Program doesn’t meet your needs
less than the monthly cost of most cell phone, cable TV, & wideband internet services
supports > 4000 audio files in the Library
Automate up to a Week in advance with up to 100 events per hour
Voice track your automated hours quickly and easily with Xtreme
Music Scheduling, powerful and flexible is standard in Xtreme
‘X-sched’ traffic software for a separate traffic office is standard with Xtreme
Arrakis ‘X-Edit-Pro’ production software is ‘Free’ with the Solutions Program
‘Xtreme-studios’ software for PC only News rooms and Remotes is standard with Xtreme

Digilink-Xtreme for ‘Live Air’ & ‘Automation’
Software features
the optional PC USB module contains a built-in, Windows compatible,
USB sound card for USB connection to a PC. (maximum of one module
per PC)
‘Free’ Digilink-Xtreme software for ‘Live On Air’ with the MARC-15
Arrakis Digilink-Xtreme software will recognize the PC-USB module in
the MARC-15 console and operate in the ‘free’ mode to provide ’Live
On Air’ features that are ideal for broadcast, internet, or podcast
style radio applications.

To turn a channel on, simply push the green ON switch at the bottom of the
fader. When the channel is on, the switch will be lighted. To turn the chan-
nel off, simply push the yellow OFF button.

nel on, channel off, LED tally of channel on-off, cough, and talkback to con-
sole cue system.
OUTPUT BUS ASSIGNMENT
The green PGM and AUD and UTL buttons above the slide fader assign the
channel to any (or all) of the main audio mixing buses: Program & Audition
& Utility. 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.
CUE
The cue button is a status lamp indicating whether cue has been activated
by turret logic from a remote studio. When lighted, the mic in the remote
studio has been placed into the cue system for talkback from that mic.
Note: this cue switch does NOT activate cue in the control room because
this would cause feedback between the cue speaker and the mic.
MUTE
When the channel is turned on, the monitor and cue speakers are muted
to stop feedback between those speakers and the microphone. Muting
occurs on both the ‘A’ and ‘B’ inputs.

The PC-USB input Module
The PC USB module is ideal for interfacing the con-
sole with a Windows PC (XP or VISTA). Because the
hardware is Windows compatible, both Arrakis soft-
ware and 3rd party software (such as Adobe
Audition) will recognize and play/record from the
module. The Arrakis software is also controlled by
the module channel on-off switches to start and
stop the playlist just like a cart stack. The Record
button starts and stops a manual record from the
front panel of the module. Powerful Arrakis Xtreme
software is supplied free with this module and full
automation software is available as well under the
Arrakis Xtreme-Solutions program.
