Virtual Private Networks (VPN)

Virtual private networks (VPN) provide an encrypted connection (or tunnel) between networks or between a network and a user over a public network (such as the Internet). Instead of using a dedicated, real-world connection such as a leased line, a VPN uses virtual connections through the public network. The advantage to a VPN is that your computer can be virtually connected to a local network even though it is physically anywhere in the world where you have an internet connection. This can also be done in a safe manner not compromising your local network’s security. If you would like to manage your PCM96 units remotely you should create a secure VPN con- nection.

There are many solutions on the market today that provide VPN access. These products offer different features, methods of VPN, complexity of setup and maintenance, as well as varying levels of security. It is beyond the scope of this manual to recommend a VPN solution that will best suit the needs of your network, although you will need a VPN that is capable of passing UDP and TCP traffic (most do). The PCM96 has been tested against several solutions and should work with all VPNs that meet these criteria. Please work with your system administrator and Internet ser- vice provider to find a VPN that will best fit your network. The 3Com OfficeConnect Secure Router (model # 3CR860-95) is one solution that has been tested, and is both inexpensive and simple to set up. It provides up to two concurrent VPN connections.

Network Considerations and Limitations

•Without a VPN, there can be no access from the outside world to any PCM96 that is behind a Network Address Translation (NAT) router. (One-to-One NAT and port forwarding will not work.)

•Firewall Considerations: The PCM96 uses port 3804 (udp and tcp) to communicate with the System Architect software. Make sure that you configure your firewalls correctly so that data sent to and from this port number can traverse your network.

Network Troubleshooting

If you are having difficulty getting your PCM96 to show up in your System Architect software, here are some things that you can try to resolve the prob- lem.

Software Firewall

If the PC that you have installed the System Architect software on has a built-in firewall you need to make sure that you allow the software the abili- ty to talk on your network. Try disabling your firewall and then going offline and back online in the System Architect software. If this fixes the problem, refer to your firewall manufacturer’s documentation on how to reconfigure your firewall to allow the System Architect software and/or port 3804 tcp and udp to pass through the firewall.

Ethernet Link

Make sure that you have a valid Ethernet connection by looking at the link status lights. Most Ethernet devices will have some kind of indicator that shows the link is present. Check the following connections:

Tailored for both professional studio environments and live sound applications, the PCM96 delivers an impressive range of features that appeal to audio engineers, musicians, and producers alike.

At the core of the PCM96 lies Lexicon’s proprietary algorithm technology, which has been honed over decades of developing industry-leading reverb and effects processors. With its dual-engine architecture, the PCM96 allows users to access a wide variety of effects simultaneously. This dual-engine approach means that the processor can handle complex audio signals with unmatched clarity and precision.

One of the standout features of the PCM96 is its extensive library of reverb algorithms. From lush concert hall environments to tight and intimate spaces, the PCM96 captures the nuances of acoustic realism. Additionally, it provides advanced options for customizing reverb tails, predelay, and diffusion, allowing users to create unique soundscapes tailored to their specific needs.

Beyond reverb, the PCM96 boasts a rich selection of modulation effects, including chorus, flanging, and delay. These effects can be combined with the reverb algorithms for intricate sound design possibilities. The processor supports up to 96 kHz sample rates, ensuring high fidelity and compatibility with professional digital audio workstations (DAWs).

Another key characteristic of the PCM96 is its intuitive user interface. The front panel features a bright LCD display and straightforward controls, making it easy for users to navigate through presets and tweak parameters on the fly. Additionally, the PCM96 can be integrated seamlessly into various digital audio environments via its comprehensive connectivity options, including AES/EBU, S/PDIF, and MIDI.

The PCM96 also supports remote control and automation via MIDI, enabling users to synchronize effects with musical performances or recording sessions. This feature is particularly beneficial for live sound applications where quick adjustments can significantly impact the performance dynamics.

In summary, the Lexicon PCM96 stands out as a premier effects processor that brings together high-quality sound, innovative technologies, and user-friendly design. Its robust set of features, combined with the legendary Lexicon sound, makes it an indispensable tool for audio professionals seeking to elevate their creative possibilities in sound design and music production.
