Hill Audio was established in England during the mid 1970's, and is being credited for the invention of the rack-mounted PA mixer such as the Multimix series, but also for some successful live sound mixers such as the Soundmix, Datum or J series.

Equally successful recording mixer designs such as the Remix 24 from 1986 and the larger Concept consoles gained an excellent reputation in the market. Hill Audio was at the time also well known for the quality and performance of its amplifier designs, which sold several ten thousand pieces over the existence of the successful DX and LC series.

Since 2006, we have re-invented ourselves to broaden our focus from live sound to installed sound and recording, so whether event, concert, conference, commerce, recording or leisure, Hill Audio has a product to match the specific requirements of the application - both in foreground and background music reproduction, as well is in music production or broadcasting.

The Adagio series is the perfect loudspeaker choice for background music applications. Whether at low volumes like in retail environments or at more elevated sound levels as in hospitality use, there is a choice for every purpose in this range. Being tuned for the high dynamics and extended frequency response of pop music, this line of speakers not only looks good, but first and foremost provides a vivid and pleasant listening experience.

The woofer is protected by a sturdy grille, and electrical connections are made via binding posts in a recessed compartment on the speaker's back side. The same compartment also houses the transformer tap settings on versions with built-in line transformer, which is an option on the 4" and 6" size variants ("T" suffix). The two available colors (black, white) allow for an easy integration into any architectural envrionment. A truly versatile speaker range at an affordable price.

The QPA-2800 follows contractor requirements for a compact, powerful and easy-to-handle 4-channel amplifier to drive multichannel low-impedance loads. Built on the proven LPA series' technology, this amplifier basically comprises of two LPA-1400 in one case. Each pair of channels can be run in stereo, bridge or parallel mono mode. A newly designed high-CMRR input circuit proves useful where source and amplifier are far apart.

The LPA-based hybrid approach to amplification, using proprietary digital control of limiters and filters while retaining a purely analogue signal path, gives high dynamic reserves without compromising tonal purity. Proven linear power supply technology yields predictability at any power level. Two large 3 colour LCD displays clearly indicate the status at any time, and are legible from long distances. Sources can be connected via Combo input sockets or 3.5mm Phoenix terminals, and loads can be connected both via Speakon and via terminal strips.

Despite its compact size and focused feature set, the Hill Audio LMD-502 can serve a multitude of applications, from one-man bands to podcast production and video post-production. Basically any situation where a single microphone signal needs to be properly pre-amplified and equalized, and then mixed with a range of stereo signals, calls for the LMD-502's presence.

Unlike other mixers of its format, the LMD-502's microphone input is not limited to dynamic microphones, but can also handle condenser microphones thanks to its switchable +12V phantom power supply. The external power supply, connected to the mixer via a locking connector, provides for low hum and noise and thus outstanding audio performance. A metal case not only provides for an elegant appearance but also ensures rigidity for the use in mobile applications. A small but extremely versatile mixer!
