DISTRIBUTION AMPLIFIERS
The ES-209A is a 1 x 12 Video Distribution Amplifier combined with a 1 x 12 Dual Audio
Distribution Amplifier. The ES-224 is very similar except that it is a 1 x 24 version. They are
primarily designed to meet the needs of tape duplication systems as well as installations
that require Audio and/or Video Distribution. Front panel-mounted controls are provided
to adjust Video (EQ & Gain) and Audio (Left & Right Gain) output signals.
Features:
• Left & Right Channel Audio Gain Controls • Loop-thru Audio & Video Inputs
• Professional Audio & Video Quality • Accepts Balanced or Un-Balanced Audio
• Transformerless Audio DA
• 1 x 12/24 Video DA
• 1 x 12/24 Stereo DA
• Video EQ & Gain Controls • Internal Linearity Control • Rack Mount Enclosure
The video section of the ES-209A and ES-224 may be used for signal distribution and for signal conditioning.
They are capable of delivering the very highest professional video quality. The Equalization Control (EQ) may
be used to boost chroma in recording if desired. The Gain Control provides an output from .5 Vpp to 1.5 Vpp
(with 1 Vpp input).
The audio portion of the unit is designed to
create 12/24 identical copies of the stereo
input drive signals. Response, distortion
and noise specifications make the stereo
performance of the DA ideal for tape
duplication or signal distribution, The
audio DA input is balanced or un-
balanced (hi-impedance), while the outputs are medium, and will drive either 600Ω or hi-impedance inputs.
