Информация
THE 420 STEREO POWER Amplifier IS A TWO-CHANNEL POWER Amplifier
for use in professional and commercial audio systems. The 420 may be operated as a two channel Amplifier with 20 watts (RMS) per channel, or as a single channel Amplifier capable of 40 watts (RMS) output (bridged-mono mode). The 420 is intended for use in powering near-field monitors, small reference speakers used for radio or audio for video reference, small paging
speakers, multiple pairs of headphones, or as a general purpose line driver/distribution Amplifier.
The 420 is easy to install and simple to operate as well. When used as a stereo Amplifier, a single ganged potentiometer controls the level
of both channels. As a 2-channel amp there’s an independent level control for each channel. In conjunction with the level controls each channel has a bright red LED to indicate the onset of clipping. A front panel MODE switch mono sums (mixes) the two inputs. This feature is handy for broadcast and recording engineers who wish to check the mono compatibility of their signals. Commercial sound engineers can use this feature to mix paging signals or paging and music signals. In recording studios and other similar applica-
tions, the 420 makes an ideal headphone Amplifier. You can drive one pair of phones from the front panel jack, or many pairs from
the rear panel terminals. In fact, the 420 will drive multiple professional headphone sets such as the AKG K-240 to 122 dB SPL! While the 420 is compact (1 rack space) and low cost, one should not overlook it’s impres-
sive performance data. Total harmonic distortion (THD) is less than .04% at 1 watt output (see the back of this page for complete specifications). The 420 is truly a professional amplifier—clean, crisp sound reproduction and
total freedom from noise. As an added feature, the 420’s relatively low stray field emissions allow it to be racked next to a wide variety of audio and video equipment without adversely affecting the equipment’s performance.
