Linea Research Amplifiers Deliver In New System Serving Legendary San Francisco Venue

Ayre Productions employs 44C and 88C Series to drive a wide range of loudspeakers in new system for the revitalized Lizzie’s Starlight at the Sir Francis Drake Hotel.

Lizzie’s Starlight, an entertaining and dining establishment on the roof of the Sir Francis Drake Hotel, an anchor of San Francisco’s Union Square since 1928, has been remodeled and equipped with a new audio system driven by Linea Research 44C and 88C Series power amplifiers.

The system project was handled Ayre Productions of Chicago, the company behind multiple projects for owners Kimpton Hotels. The renovation of Lizzie’s Starlight (originally dubbed the Starlight Room) saw the entire space torn down to bricks, bare floor, and bare ceiling and completely remodeled.

“We worked on this project for two years, and the design has changed three or four times,” notes John Wagner who, along with brother Joe, is co-founder and co-owner of Ayre Productions. “We’re a Pioneer Pro Audio dealer, and we specified Pioneer loudspeakers before we were involved with Linea Research. Pioneer partners with another amplifier company, so we had planned to use those amps.

“But then we were introduced to Linea Research amplifiers through Martin Audio, another of our lines,” he continues. “We did comparative listening tests with Linea Research amps and two other major brands, including the amps in our original design, and the Linea Research amplifiers came out on top because of their warmth and overall clarity. So we not only changed the design for Lizzie’s Starlight, we sold off our other amplifiers, and now we just install Linea Research.”

The biggest challenge was a room combining scheme. Although the overall space is not all that large, it’s divided into four meeting rooms of varying sizes (one of which includes the main dance floor) that can be combined into a single space. It’s a configuration that enables the venue to draw daytime business for meetings and other events, in addition to its traditional identity as a nightclub.

“Because of the size of the four areas, we made the focal point the center of each area,” explains Wagner. “With the rooms separated, there is minimal bleed-over between rooms. The client wanted a different, yet fun-looking, speaker to accent the new décor, so we choose Pioneer Pro Audio XY-2 loudspeakers, with XY-81s for small fills where the XY-2 wasn’t needed. The South Room, with the dance floor, is set up with two XY2s, two XY-81s, and a XY215S subwoofer, plus Pioneer Pro’s new CM-C56T in-ceiling speakers in acoustically treated ceilings. The North, East, and West rooms use various combinations of XY2 and XY-81 loudspeakers and XY-115s subwoofers. The host area, elevator entrance, and restrooms have acoustically treated ceilings with CM-C56T in-ceiling speakers.”

The Pioneer XY-2s and subwoofers are driven by a 4-channel Linea Research 44C10 and two 8-channel Linea Research 88C06 amplifiers. Optimized for installations, the 44C10 provides 2,500 watts RMS per channel into 2 ohms, 4 ohms, or 70/100 volts and 1,500 watts RMS into 8 ohms, with all four channels driven. The 88C06 supplies 750 watts RMS per channel into 2, 4, or 8 ohm loads or 70/100 volts, with all 8 channels driven.

“Most company rate their power amplifiers in peak power, so when I started using Linea Research amplifiers, I had to get used to designing based on RMS, where a 10,000 watt amp is really 10,000 watts,” Wagner notes. “We can easily run four subwoofers on one Linea Research amplifier. We use Furman power sequencers that provide 20A per amplifier, and I’ve yet to have a problem with that not being enough.”

The new audio system at Lizzie’s Starlight is managed by a Symetrix Prism 12×12 and a Prism 0x0 DSP. “We installed a Dante audio network throughout the space, and each meeting room has two Dante connection points, although in one meeting room the two points are the same connection,” Wagner reports. “However, I did not use the Dante version of the Linea Research amplifiers. Maybe I would if I were doing it again but feeding the amplifiers from the 12 analog outputs of the Symetrix Prism 12×12 DSP works well.”

All processing for the Pioneer loudspeakers and subwoofers is done using the Linea Research amplifiers’ onboard 96 kHz DSP. “I rebuilt all of the profiles for the Pioneer speakers, loading them into the amplifiers,” Wagner adds. “With Linea Research’s programming GUI, I was able to do whatever I needed. Aside from signal routing, I mostly use the Symetrix DSP for special needs and last-minute things like live-microphone feedback control.”

Lizzie’s Starlight is now open for business, and the new sound system is fully operational. “They are very happy with the sound and performance of the new audio system,” Wagner concludes. “It is a night and day improvement over the system they had before.”
