While the ACCESS 2 USB has been optimized to provide complete mobility and solid reliability, the ACCESS Rack has been designed as its perfect studio counterpart. The 1U 19 rack mount ACCESS features balanced stereo XLR inputs and outputs, AES I/O on XLR, Ethernet port, POTS modem, multiple USB ports, serial and contact closure ports. ACCESS Rack can be directly controlled with a keyboard/ video/mouse, a USB Touch screen monitor or driven with a standard web browser.
ACCESS will work on a wide variety of wired and wireless data circuits, including:
- Wired Ethernet Networks - Cable, DSL, T1, T3, etc.
- Wireless Networks - 802.11b,g,n WiFi
- 3G / 4G Cellular Data Networks - EVDO, UMTS, WiMax
- Satellite Terminals
- POTS Analog Telephone Lines
- Public Internet - Uses Revolutionary BRIC Technology, designed to overcome the innate unreliability of the public Internet
ACCESS is also a full-featured POTS codec:
- Use ACCESS to make a POTS-to-POTS connection. Dial up a Comrex POTS codec (including Matrix, Vector or BlueBox).
- You can deliver 15 kHz Stereo on a single POTS line when connecting to another ACCESS.

Developed to overcome the inherent instability of challenging data networks like the public Internet, BRIC Technology provides a sophisticated suite of tools that allow for high-quality, low-latency, stable transmission of audio over a wide variety of data networks. Intelligent, Dynamic Jitter Buffer Management, BRIC Algorithms and the BRIC-Traversal Server all work together to provide the most stable Audio over IP transmission platform available for remote broadcast.
IP networks are available virtually everywhere. ACCESS 2USB offers several ways to get connected. You can utilize the included USB Wi-Fi modem to connect to widely available HotSpots or use the integrated Ethernet port to connect to wired DSL or broadband cable IP networks. Either of the two USB ports will accommodate connections to 3G/4G cellular data networks using Comrex supported USB devices. ACCESS 2USB also includes a USB POTS/PSTN modem for use on legacy analog phone lines.
Not all IP Networks are created equally. In fact, some can be quite challenging such as certain Wi-Fi and 3G cellular connections. Comrex has developed BRUTE (BRIC UDP Transmission Enhancement) to help maintain stable and reliable transmission on marginal networks. UDP Reliability and Congestion Avoidance modes provide an extra measure of error protection with a minimal increase in latency.
AAC (Advanced Audio Coding)
ACCESS 2USB includes our popular HQ algorithm suite for backward compatibility, but now includes AAC modes as standard. For broadcasts that require the highest audio quality available, AAC delivers. AAC, AAC-LD (low delay), HE-AAC (high efficiency), HE-AACv2 and AAC-ELD (enhanced low delay) can accommodate nearly any bandwidth, latency or audio quality requirement. In particular, the AAC-ELD mode provides the perfect balance of low bit rate, low delay, and high quality audio to get the best out of remote broadcasts.
Connect and Control
ACCESS codecs offer several ways to be configured, controlled and managed. Comrex BRIC Device Manager is a free Windows app that allows for easy IP configuration of ACCESS codecs as well as firmware and license updates. BRIC-Remote Control, also available at no charge to Comrex customers, provides an easy way to connect and control a fleet of ACCESS codecs from a central location. Comrex BRIC-Traversal Server, managed by Comrex and included with the ACCESS products, provides a simple way for ACCESS codecs to "see" each other from behind Firewalls and private LANs.
