General Specifications
Applications
The ATSC-1 is intended primarily for use in machine rooms and edit bays where on-the-spot, high-fidelity confidence
monitoring of six channels is required. Thorough magnetic shielding (less than 1 Gauss at any surface) allows installation
of the unit immediately adjacent to video monitors. Designed for optimum reproduction in relatively close-up use, the
ATSC-1 unit has more than enough acoustic output, even for noisy transmitter sites (104 dB SPL at two feet), and a
surprisingly broad and smooth useable frequency response of 40 Hz to 18 kHz.
Designed, built, and rigorously tested in the U.S., the ATSC-1 monitor is backed by a strong two year warranty and a
"satisfaction guaranteed" return policy.
* On special order, custom combinations of selected
channels are available; either in lieu of, or in addition
to, the regular selections.
Units are certified to meet, at time of manufacture, all currently applicable product safety and EMC requirements, such as those
of UL and CE. 0 dbV ref. 0.775V RMS. Features and specifications subject to improvement without notice.
