The Studiomaster Sense12A is a compact 12-inch active stage monitor designed for performers, bands, rehearsal rooms, venues and portable PA systems. Its coaxial driver arrangement, dual Class-D amplification and onboard DSP combine to provide clear, focused monitoring while keeping the cabinet footprint to a minimum.

A fixed 43° wedge angle directs sound towards the performer when the Sense12A is positioned on the floor. This makes it particularly suitable for close-range vocal and instrument monitoring without taking up unnecessary space at the front of the stage.

The carpet-covered enclosure and durable steel grille provide protection during regular transportation and live use, while its 15kg weight keeps the monitor manageable for mobile performers and sound engineers.

Coaxial Driver Design

The Sense12A uses a 12-inch low-frequency driver with a centrally positioned high-frequency compression driver. This coaxial arrangement aligns the high and low-frequency sources, helping produce consistent coverage and a focused sound across the listening area.

The 12-inch woofer uses a 65mm voice coil, while the neodymium high-frequency compression driver has a 44mm voice coil. The system provides 80° horizontal by 80° vertical coverage, giving performers a broad and evenly distributed monitoring area.

A frequency response of 55Hz to 20kHz allows the Sense12A to reproduce vocals, acoustic instruments, guitars, keyboards and playback material with a balanced full-range sound.

Dual Class-D Amplification and DSP

The built-in amplifier delivers 300W RMS, divided between 260W for the low-frequency driver and 40W for the high-frequency section. Programme power is rated at 600W, with a peak power rating of 1200W and a maximum SPL of 127dB.

Dual Class-D amplifier circuits provide efficient operation while helping keep the enclosure compact and relatively lightweight.

The integrated 24-bit, 48kHz DSP includes equalisation, Live and Monitor operating modes and adjustable delay. These processing options allow the response to be adapted when the Sense12A is being used as a floor monitor or as part of a conventional PA system.

Flexible Input Connections

Two combined XLR and jack inputs allow audio signals to be connected from a mixing console or other compatible equipment. A separate 3.5mm input provides a convenient connection for suitable playback devices.

An XLR output provides an onward audio connection for linking another active stage monitor or powered PA speaker.

These connection options make the Sense12A suitable for conventional stage foldback, rehearsals, small performances, presentations and portable sound reinforcement.

Floor Monitor or PA Speaker

Although primarily designed as a floor monitor, the Sense12A can also be mounted vertically using its 35mm pole socket. This allows it to operate as a compact PA speaker or side-fill monitor when used with a suitable speaker stand.

The Live and Monitor DSP modes help optimise the system for its chosen position. Its compact coaxial design also makes the Sense12A useful where stage space is limited or a discreet monitor is required.

Q: What connections are available?

A: The monitor has two combined XLR and jack inputs, a 3.5mm audio input and an XLR output for connecting additional compatible equipment.

Q: What DSP functions are included?

A: The 24-bit, 48kHz DSP provides equalisation, Live and Monitor operating modes and adjustable delay.

Q: Can the Sense12A be mounted on a speaker stand?

A: Yes. A built-in 35mm pole socket allows it to be mounted vertically on a suitable speaker stand.

Q: Can the Sense12A be used as a PA speaker?

A: Yes. Its 35mm pole socket and selectable Live operating mode allow it to be used as a compact powered PA speaker as well as a floor monitor.

Q: What is the monitoring angle?

A: The cabinet has a fixed 43° wedge angle designed to direct sound towards a performer positioned close to the monitor.

Q: Can another active speaker be connected?

A: Yes. The XLR output provides an onward audio connection for another compatible active monitor or PA speaker.

Q: Does the Sense12A have Bluetooth?

A: No. The Sense12A does not include Bluetooth. Audio sources are connected through the XLR/jack or 3.5mm inputs.
