Biamp 901.0354 Tesira SAC-4

Product Overview

The Biamp Tesira SAC-4 is a 4-channel mic/line modular input card with Ambient Noise Compensation for Tesira SERVER and SERVER-IO devices. It is the input card integrators specify for paging and announcement systems in spaces where background noise rises and falls, such as houses of worship, auditoriums, and large multi-purpose rooms. This Tesira ambient noise compensation card features Biamp's AmbientSense algorithm, which intelligently separates ambient noise from program material. The SAC-4 mixes and matches with other modular I/O cards in either Tesira server chassis.

Product Description

Each SAC-4 provides four channels of mic or line level audio input with Ambient Noise Compensation on balanced, plug-in barrier strip connectors. The card's AmbientSense algorithm distinguishes ambient noise from program material or announcements, which improves compensation performance compared with traditional ambient noise systems that can be fooled by the program signal itself. In Tesira software, control is separated into distinct blocks for the mic/line inputs and for the ANC processing, so the system designer can use the inputs independently and apply the ANC algorithm to signals from a different part of the system. This flexibility suits AV system integration projects where announcements must remain intelligible over a changing crowd, such as worship spaces, government facilities, and commercial meeting spaces. Software configuration for each input includes gain with clip indicator, phantom power on/off, mute, level, and signal invert. The card incorporates AES48-2005 grounding and EMC practices, is RoHS compliant, and carries Biamp's 5-year warranty.

Key Features

• Four Mic/Line Inputs With ANC — The card provides four channels of balanced mic or line level input with Ambient Noise Compensation on plug-in barrier strip connectors.
• AmbientSense Algorithm — AmbientSense intelligently distinguishes ambient noise from program material to improve compensation accuracy.
• Separate Input and ANC Blocks — Software separates mic/line input control from ANC processing so the algorithm can be applied to inputs elsewhere in the system.
• Full Input Control — Each input offers gain with clip indicator, phantom power on/off, mute, level, and signal invert.
• Mix-and-Match I/O — The SAC-4 can be combined with other modular input and output cards in a Tesira SERVER or SERVER-IO.
• Standards Compliant — The card incorporates AES48-2005 grounding and EMC practices and is RoHS compliant.
• 5-Year Warranty — The SAC-4 is covered by Biamp Systems' 5-year warranty.

Typical Applications

• House of worship
• Auditorium
• Multi-purpose room

Frequently Asked Questions

Which Tesira devices accept the SAC-4?
The SAC-4 installs in Tesira SERVER and SERVER-IO devices and can be mixed and matched with other modular I/O cards.

What does Ambient Noise Compensation do?
It adjusts audio in response to changing background noise so announcements and program material remain intelligible in busy spaces.

What is AmbientSense?
AmbientSense is Biamp's algorithm that distinguishes ambient noise from program material to improve compensation accuracy.

Can I use the inputs without ANC?
Yes. Software separates the mic/line input and ANC blocks, so you can use the inputs independently or apply ANC to signals elsewhere in the system.

What input control is available?
Each input offers gain with clip indicator, phantom power on/off, mute, level, and signal invert.

Where is the SAC-4 typically used?
It is common in houses of worship, auditoriums, and other spaces where background noise levels vary during use.

What warranty applies?
Biamp covers the SAC-4 with a 5-year warranty.
