1.0 WARNINGS
Prior to installation and use of this product, the follow­ing WARNINGS should be observed.
4. Only use replacement parts recommended by Pelco.
5. After replacement/repair of this unit’s electrical components, conduct a resistance measurement between line and exposed parts to verify the ex­posed parts have not been connected to line cir­cuitry.
2.0 SCOPE
The information contained within this manual covers the EA2010 Post Equalizing Video Amplifier .
3.0 DESCRIPTION
The Pelco EA2010 provides a low cost, highly effec­tive means of maintaining CCTV picture quality in runs of up to 3000 feet (914.4 m) of RG59 cable.
Through panel controls provided for adjustable overall amplifier flat gain of 1 to +8 dB plus adjustable high frequency boost of 0 dB to greater than 18 dB at 12 MHz, mainlining full video amplitude, contrast and detail.
The EA2010 features all solid-state circuitry and is sup­plied with a U.L. Listed wall transformer. Applications should be for POST-EQUALIZATION only (located near the monitoring equipment); use as a pre-equalizer is discouraged.

3.1 OPTIONS
DT200 Dual desktop mount kit; two units
can be mounted side-by-side in one desktop chassis.
R300 Rack mounting kit. Up to three (3)
units may be racked horizontally In a single rack kit. Blank filler panels provided for use when less than three units are racked.
4.0 OPERATION
In the absence of an oscilloscope, a less precise (but often equally satisfactory) adjustment can be made as follows:
1. Set the GAIN and BOOST controls approximately 1/3 turn from fully counterclockwise.
2. Adjust GAIN control for satisfactory overall pic­ture contrast.
3. Adjust L.F. BOOST control for optimum detail. T oo much boost (clockwise) can cause picture in­stability and/or smearing (trail).
Optimum performance Is achieved if an oscilloscope a standard EIA resolution chart are used in making gain and boost adjustments. The (GAIN control should be adjusted for an output level of 1 volt p-p and the L.F. BOOST control should be adjusted for minimum tilt during sync pulses. The H.F. BOOST control is then adjusted for optimum resolution wedge reproduction.
If the use of a resolution chart is precluded, the H.F. BOOST control should be adjusted for maximum sharp­ness of sync pulse edges—without overshoot.
4. Adjust the H.F . BOOST control to further optimize picture detail. Note that the effectiveness of this control is hardly perceptible unless very fine pic­ture detail is present in the camera signal output. An excessive setting of this control (clockwise) can, however, increase picture noise.
Refer to Figure 1 for a typical system configuration.
