The new SACOM DS8400/8800 digital wireless system

SACOM is now shipping the new DS8400/8800, a full conference or stage microphone digital wireless system with 24-bit digital transmission providing the ability to tailor wireless audio devices to specific application environments.

The 1RU receiver chassis holds up to eight receiver modules. The system has a built-in antenna distribution amp so up to eight chassis (or 64-channels) can be daisy-chained together and operate with a single pair of extension antennas.

The antenna run can be up to 75 feet with RG58 or about 200 feet with RG8.

SACOM’s 256-bit encryption algorithm conforms to the US Government AES (FIPS PUB 197) specifications. Systems are also available without the encryption feature.

The system is built around NiMH batteries but will run on alkaline batteries. A free docking station is included with each receiver.

The transmitters can also be powered using a mini-USB charger or power from the USB port on a computer.

The DS engine’s RF technology allows for secure transmissions via certified data encryption without adding latency.

Latency is 2.8 mS digital out or 3.8 analog out. Analog and digital out operate simultaneously in parallel.

The same 32-channls can be repeated every 25 or so meters within a building. Output power can be selected for 1, 10, 25, or 50 mW, with 25mW providing a range of 100 meters line-of-sight.

The system includes SACOM Remote Software that controls all aspects of the system via USB, RS232 or Ethernet. Each receiver has its own MAC address and programmable IP address, providing daisy-chain I/P control without the expense of a hub.

The software provides a way to assign any two adjacent channels as a redundant pair (pilot and copilot). If anything happens to the “pilot” (i.e., there is an RF hit or a battery dies) the “copilot” takes over instantly without any audible hit or disruption.

The system has up to 25 pins of GPIO contact closures. The gooseneck and boundary mic buttons can be programmed to cause an audio mute or a logic mute.

The logic mute toggles the GPIO. This allows the automated mixer to monitor the ambient room noise level when mics are muted. GPIO can also be used to mute all mics simultaneously for a sidebar.

SACOM provides a 1/4-inch balanced mixed audio output on the front panel. The receiver and a speaker-on-a-stick is all that is required for an impromptu meeting with eight wireless microphones.

The system operates in the 902-928 MHz ISM band in North and South American, as well as some Pacific Rim countries.

The company’s engineers provide free antenna system design for specific projects and set up parameters so the equipment arrives at the job site ready for “plug-n-play.”

The new DS8400/8800 digital wireless system is made in the USA.
