Housed in a compact (3.25 in. x 6.5 in.)
chassis, the Model 6454 Headend
Driver Amplifier can be powered by
220 V AC, 230 V AC, 240 V AC, or 24
V DC. The amplifier has a minimum
RF gain of 17.0 dB. It uses a PHD gain

block to obtain optimum distortion
performance at operational output levels.
Optional accessories include various
values of standard Scientific-Atlanta
pads and equalizers. A pre-drilled P3
panel kit (part number 502417), designed
for mounting the unit in a standard
headend rack is also available. This kit
provides access to the -20 dB test points
directly from the face of the P3 panel.
