ATC Professional SCM105AC PRO

Productbeschrijving

ATC are very pleased to announce the forthcoming release of a new mid-size centre channel studio monitor, the SCM105AC Pro. This new model is based on the existing SCM110A Pro but has been specifically designed for use as a centre channel in surround and immersive audio applications, featuring a symmetrical driver layout and greatly reduced cabinet height, to simplify install in crowded control rooms. Two product variants are available, the SCM105AC, which is designed to be used free-standing and the SCM105AiWC, which is designed to flush-mount in-wall.

SCM105AC Pro
The SCM105AC Pro is designed to be used free-standing (stand-mount) and the design and performance very closely mirrors the highly successful SCM110A Pro mid-field studio monitor. It shares the same combination of dual 9"/234mm SL bass drivers, 3"/75mm Superdome mid-range and 1"/25mm S-Spec tweeter. Amplification is handled by the same 350W Amp Pack delivering 200W, 100W and 50W to the bass, mid and HF sections respectively and the drivers are precisely integrated via 4th order LR electronic crossovers.

O v e r v i e w
- Low height cabinet design to simplify install in crowded control rooms.
- Symmetrical driver layout.
- Ideal partner for the SCM50/100/110A Pro stereo monitor loudspeakers*.
- Dual 9”/234mm SL bass drivers, 3”/75mm soft-dome mid, 1”/25mm soft-dome tweeter.
- 3-way active design featuring precision active crossovers & discrete MOSFET power amplifers, integrated as proprietary ‘Amp-Pack’.
- In-Wall variant with remote amplifier also available – the SCM105AiWC Pro.
- Wide dynamic range and bandwidth.
* Can also partner SCM150A Pro but max SPL capability must be considered
