Leipzig’s 4-Star Ramada hotel has completed a digital audio upgrade to the latest technology using Rane’s HAL System. The 1,000 square meter (10,800 sq. ft.), 15 meeting room conference center offers soundproof walls, modern presentation technology, and high-speed wi-fi. Every room opens to a landscaped park-like space for peaceful breaks from meetings.
The HAL System’s RAD devices deliver digital audio via shielded CAT 5 cables all the way to each rooms’ wall jack. The old analog PA system was causing a variety of confusing audio control and quality problems and lacked routing flexibility. Since all the 24-bit, 48 kHz A/D and D/A conversion happens in each room RAD or portable automixer, the audio quality is stunning.
The central control room houses Rane’s HAL1 DSP with four EXP1 expansion devices and three DR3 remote controls for the staff to adjust system presets throughout the building. Each meeting room’s media cabinet houses dual-XLRs in a RAD7 and a DR3 remote for local level control, source selection, and tone control. Background music is distributed throughout the meeting rooms, lobbies, bar, restaurants and the conference center.
All meeting rooms have RJ-45 jacks that accept a Rane AM1 Automixer to add microphones to any room when needed. The mobile mixer also utilizes shielded CAT 5 cable for digital audio delivery to the control room HAL. The patented technology in the Rane AM1 & AM2 Automixers allows them to be cascaded as stand-alone devices, or as add-ons to any HAL System. When used as RAD devices (add-ons), the system automatically shares microphone gain between the main HAL DSP and these portable mixers. This provides superior fidelity and noise immunity using digital transport and the ultimate in feedback freedom since mics in RADs, AM mixers, EXP expanders and the HAL work flawlessly together utilizing a gain-sharing automixing algorithm.
The design and installation were overseen by Holger Thorn, of MSV Electronics in Leipzig. “The hotel operations and technical directors are extremely satisfied with the new higher fidelity, trouble-free system, its ease of operation and the new signal routing flexibility.”
