Pre-amp mixers form the essential heart of any high-quality public address (PA) system, voice alarm system, or multi-zone commercial audio solution. These versatile devices expertly combine multiple audio sources — from microphones and line-level inputs to media players — while providing clean amplification and precise control before the signal reaches your power amplifiers.
Whether you need simple microphone pre-amplifiers with phantom power, multi-channel mixers with priority paging, or advanced multi-zone audio mixers and digital matrix mixers, our range delivers the flexibility modern installations demand. Many models offer rack-mountable designs, network control via Ethernet, Bluetooth/USB connectivity, and features like auto-mixing or individual zone EQ for superior sound management.
These pre-amp mixers are ideal for a wide variety of environments, including offices, schools, retail stores, hotels, shopping centres, warehouses, and transportation hubs. They excel in background music distribution, clear voice announcements, emergency paging, and integrated voice alarm systems where reliability and intelligibility are critical.
Built for professional installers, our pre-amp mixers ensure low-noise performance, seamless source routing, and easy integration with existing PA and voice evacuation setups. Explore single-zone to eight-zone options with priority controls that guarantee important messages are always heard first.
Upgrade your audio infrastructure with dependable pre-amp mixers from leading brands — engineered for clarity, control, and long-term performance in demanding commercial environments.
It is the control unit that combines microphones, line sources and media players, sets levels and routing, then sends a clean line-level signal to the power amplifiers. It does not drive loudspeakers itself. Offices, schools, retail, hotels and transport hubs use them for BGM, paging and multi-zone audio.
A pre-amp mixer only mixes and pre-amplifies. A mixer-amplifier has the power amp in the same box and connects straight to 100V or low-Z speakers. Choose a separate pre-amp mixer when you need more zones, more inputs, or larger amplifiers than a single mixer-amp can provide.
A zone mixer lets each area (reception, restaurant, warehouse, car park) have its own source and volume. Two-zone units suit a simple shop-plus-store; four- to eight-zone mixers suit hotels and multi-wing buildings. The mixer still needs a power amplifier (or one amp per zone) after it.
When someone pages, the mixer automatically turns the background music down so the announcement is heard. That is essential in retail, schools and warehouses. Check that the mixer has a dedicated paging-mic input and priority on the zones you need.
Yes if you use condenser gooseneck or boundary microphones. Many install mixers offer 12 V or 48 V phantom on mic inputs. Dynamic paging mics usually do not need it. Do not send phantom to a line input or an unbalanced music source.
A matrix mixer can send any input to any output, often with EQ per zone and Ethernet or web control. Use one when routing is more complex than “music plus one mic to every room,” or when the client wants to change sources from a PC or control system.
An auto mixer (automatic microphone mixer) turns unused mics down so you do not get noise and feedback from several open microphones. That suits council chambers, conference rooms and worship spaces with multiple mics more than a shop BGM rack.
Most install mixers in this range are 19-inch rack units designed to sit with the amplifiers. Compact single-channel mic preamps may be free-standing. Plan rack space, ventilation and rear connections before you choose a 2-zone versus 8-zone chassis.
The mixer provides the programme and paging signals; a 100V or VA amplifier does the loudspeaker drive. Some mixers are used in voice-alarm racks, but the life-safety certification sits with the amplifier and EN54-24 speakers, not with a general-purpose BGM mixer. Confirm the project specification.
Commercial Audio Solutions stocks zone mixers, mic/line mixers and digital matrix mixers from brands such as Cloud, Bosch, TOA, Ecler and Tascam.
