British loudspeaker experts ATC have announced the upcoming release of the SCM25A Pro Mk2, an updated and improved version of their popular compact three-way active monitor.
New 1-inch/25mm soft-dome Tweeter
The headline feature of the Mk2 is the inclusion of ATC’s own SH25-76S high-frequency driver, which will take the place of the OEM unit used in the current model. The unit is manufactured in-house by ATC with their usual no-compromise approach to engineering, and has been used since 2015 in a number of the company’s other products, including the SCM110A Pro and SCM150A Pro.
The tweeter is a 1-inch/25mm soft-dome design which, unlike almost any other alternative on the market, employs a dual-suspension system designed to better support and control the coil and dome motion. The company claim that this makes for a narrower magnetic gap, resulting in higher magnetic flux and allowing the unit to offer an extended high-frequency response whilst lowering third harmonic distortion.
Mids, Lows, & Amps
Frequencies between 380Hz and 3.5kHz are taken care of by ATC’s acclaimed three-inch/75mm soft-dome mid-range driver, a unit that features in eight of their Pro range monitors, delivering the clear and revealing mid-range detail that the company have become renowned for. Taking over below 380Hz is a 6.5-inch/160mm proprietary bass driver which utilises a carbon-loaded paper cone along with a short-coil motor.
Power is delivered courtesy of a three-way Class A/B amplifier mounted on the rear of the cabinet. Each drive unit benefits from its own individual amplifier, with crossover duties carried out by fourth-order Linkwitz-Riley filters. FET peak limiters are in place to reduce amplifier hard-clipping, with their activation displayed by a change of colour on the front panel power LEDs. As with the cabinet and drivers, the amplifiers used in the SCM25A Pro Mk2 are designed and manufactured in-house by ATC.
Balanced inputs are available on XLR sockets, with users able to adjust input sensitivity, and introduce a low-frequency boost of up to 3dB from controls on the rear panel. Power is accepted on a standard IEC mains inlet.
“We feel the new tweeter lifts the capability of the SCM25A Pro Mk2 to a higher level, retaining the outstanding balance of the monitor, but extending the high-frequency response and reducing distortion to really help lower-level detail in the high-frequency band cut through. This will greatly aid faster decision-making and outstanding translation outside of the studio.” - Richard Newman, ATC R&D Manager
