Features

The ATSC-1 is a powered stereo monitor designed specifically for flexible, comprehensive monitoring of six analog audio

channels associcated with "Surround Sound" programming. The unit is 2RU in size, for excellent fidelity without using

excessive rackspace in the critical ‘operating zone’ of rack bays and consoles. The ATSC-1 input accepts six separate

analog signals. These audio inputs can handles monitoring requirements throughout the facility.

The speakers and amplifiers are arranged in the popular Wohler “biamp summed bass stereo” configuration: bass

frequencies from ALL selected channels are summed into a 20W amplifier, which drives the woofer. The two side channel

amplifiers and speakers reproduce, in stereo, only the mid- and high- frequencies. Note that the center speaker (the woofer)

is NOT a dedicated Center nor LFE speaker. There is also a headphone output which mutes the speakers while in use.

Six wide-range LED bargraph level meters are provided for all six channels for accurate metering. Twenty bicolor

segments display signal levels according to either PPM and VU standards, as selected by the user.

Both Left/Right and Front/Rear (Surround) "Phase"/Polarity LED indications are provided, to alert of possible cancellation

from mixdown in any likely home playback situation.

To isolate possible faults, rotary switches let the operator route any one or pair of inputs to left and right speaker channels

for acoustic monitoring. Or, a toggle switch mixes all six channels down to two for listening to all channels at once.
