Theory Audio Design Introduces Two High-Power 4-Channel IP Amplified Distribution Loudspeaker Controllers

Available to order now, the DLC-1000.4 and DLC-1500.4 are high power and extremely flexible amplifier/controllers solutions for residential and commercial distributed audio applications.

Dallas, TX – CEDIA Expo 2022 – September 29 – October 1, 2022 – High-end audio brand, Theoretical audio design, announces the DLC-1000.4 and DLC-1500.4 distribution loudspeaker controllers. Ideal for any residential or commercial installation where high power distributed or surround sound is required, each model offers 4 channels of intelligent power (up to 1500W per channel), full DSP matrix and is TCP/IP controlled via a wired connection . , or directly via its on-board Wi-Fi access point.

Theory’s product ecosystem is unique in that it offers many of the performance qualities of professional audio products – effortless dynamics, high efficiency and rugged durability – but with the sonic delicacy, detail and resolution of the best high-end products. high end fidelity. Add in Theory’s intelligent full-system design approach, with automatically matched speaker DSP, and you’ve got stunning performance at a great price.

The DLC-1000.4 and DLC-1500.4 are designed to be the heart of any high-performance Theory distributed or surround sound system. With power sharing per channel pair of up to 1000W for the DLC-1000.4 or 1500W for the 1500.4, each DLC offers the flexibility to power any size system. With their configurable outputs, the DLC models can drive up to 16 Theory 16 ohm ceiling or pendant speakers in Lo-Z mode, and the DLC-1500.4 can drive up to 200 Theory architectural speakers in Hi mode -Z – or an optimal hybrid. of the two or any amount in between. This feature is especially beneficial in commercial spaces such as bars, restaurants, retail environments, fitness centers and spas where a combination of power, from quiet background noise to foreground sound strong, is required.

In hotels, educational institutions and corporate environments where there are multiple rooms of varying sizes, DLC models offer complete flexibility in terms of available power. S/PDIF master/slave functionality allows multiple DLCs to be used to cover all of these needs, and each loudspeaker controller takes up only two rack spaces. House of Worship requires reliable, high-quality voice amplification, while covering a wide distribution area with many specialist loudspeakers. DLC speaker controllers are up to the challenge, delivering high-quality amplification and superior speech intelligibility in large spaces. For home theater and surround sound systems, the DLCs are ideal for powering large screen speakers and subwoofers with up to 1000W (DLC-1000.4) and 1500W (DLC-1500.4) per channel in 4, 8 and 16 ohms or 70 V/ Hi-Z 100 V systems.

“Because DLC models can operate in either 8 ohm or 70V/100V modes, separately or in combination, and because all of our architectural loudspeakers have the same dual operation, systems of any size or complexity can easily be made from of these amazingly powerful units,” said Paul Hales, president of Theory Audio Design. “And because our in-ceiling and pendant models can operate at 16 ohms, up to 16 speakers can be driven from one only DLC without the need to invoke the 70V transformers, thus preserving ultimate sound quality. With up to 1500W per channel, there’s power in reserve to drive the largest subwoofers or screen speakers in large dedicated rooms.

DLC models are EMC and safety certified and ErP and EnergySTAR* compliant. In early 2023, Dante-enabled versions of the DLC-1000.4 and DLC-1500.4 will offer even more flexibility and ease of installation by adding Dante network audio and AES67 compatibility. A full list of DLC model specs can be found below.

CEDIA Expo attendees can view DLC-1000.4 and DLC-1500.4 at Theory booth #24035. The DLC-1500.4 will begin shipping in December for $4,250 each MSRP. Interested international dealers, representatives and distributors are encouraged to contact Theory Vice President of Sales, Mark Goldman at: [email protected] for more details.
