Compact, Portable Digital Snake System

The S-1608 and S-0816 Digital Snake are compact versions of the popular S-4000 Digital Snake system. Easy to use and quick to install, the S-1608/0816 Digital Snake system is a small format audio snake solution that offers the highest quality audio signal available in a portable snake system. The S-1608/0816 Digital Snake system is ideal for bands, corporate A/V events, seminars, rental and staging houses, House of Worship and broadcasters that needs the best possible sound quality from their audio without the high frequency losses and bulk of analog snakes.

  • - The snake comes with high quality pre-amp
  • - REAC Technology
  • - High Resolution Sound Quality
  • - Create Multiple Stage Configurations
  • - Ideal Channel Count Expansion for the S-4000 Digital Snake System

The snake comes with high quality pre-amp

Unlike analog multicore snake cables, RSS Digital Snake systems are equipped with high quality and remote-controllable mic pre-amps. The pre-amps of RSS Digital Snake systems have been specially designed for live audio applications and is made of high quality components carefully selected by Roland's engineers.

REAC Technology

The REAC (Roland Ethernet Audio Communication) protocol is an industry proven, low latency, high quality 24bit/96kHz audio transfer protocol used by the S-1608 and S-0816. The REAC protocol allows the Digital Snake signal to be “split” to as many positions as required such as monitor, broadcast and recording locations using S-4000-SP REAC Splitter or any standard gigabit Ethernet switch.

High Resolution Sound Quality

By having high quality mic-pres on stage, the sound is amplified and converted at the closest point to the sound source, providing the best possible quality audio. By using Cat5e cable instead of large multi-core copper cable, the S-1608/0816 digital snake system is immune to the “hums and buzzes” caused by electrical noise and ground issues.

Create Multiple Stage Configurations

Use Multiple S-1608/0816 Digital Snake System to create multiple stage configurations such as Left, Right and Center stage unit positions. Simply run Cat5e cables to FOH units in Front of House position for easy cable management.

Ideal Channel Count Expansion for the S-4000 Digital Snake System

The S-1608/0816 Digital Snake System can be used easily expand the channel count of the S-4000 32x8 Digital Snake System to 48x16 or more.
Mix and match S-4000 and S-1608/0816 Digital Snake systems for customizable rental and installation systems.

Remote-controllable

S-4000R or S-4000RCS provide easy remote control of all input gain adjustment, phantom power and PAD settings.

REAC technology will make easy recording split

Because REAC is based on standard Ethernet technology, the individual audio inputs coming into S-1608/0816 digital snake system can be recorded via the Gigabit Ethernet port of PC computer. DAW software to capture the audio signal is now under development by Cakewalk and will be released in the near future.
This will make multi-channel live recording easier than ever before.

*1: When a REAC Splitter S-4000-SP or a switching hub is used in-line with REAC cables, the network latency will increase by the
amount of processing delay introduced by the splitting device itself. The actual delay is dependant upon the specifications of the
splitting device, though the maximum delay amount for a single splitting device should be about 200 microseconds.

* 0 dBu = 0.775 Vrms

All specifications and appearances are subject to change.
