Single Channel Strip Amplifiers
Electronics LLC
HSA
The HSA family of single channel professional grade amplifiers covers
all bands including VHF, UHF, and FM frequencies. Automatic gain control
(AGC) circuitry provides a constant output power level independent of
the input level. These low noise and high gain amplifiers provide excellent
signal quality with low distortion for trouble-free operation over wide
ambient temperature ranges. A precision voltage regulator eliminates
performance changes due to loading or power line fluctuations.

Operation and Controls
1. Channel Identifier:
Indicates the channel for which the unit has been preset.
2. Power Indicator:
Indicates power is on when lit.
3. Output Test:
A -30 dB output test port is provided for ease of system alignment.
4. RF Gain, AGC:
The RF output level and the AGC threshold are controlled from this
potentiometer.
5. Aural Level:
This tunable notch filter allows adjustment of the audio
carrier level.
6. Input Test:
A -20 dB input test point is provided to monitor the incoming signal level.
Front Panel Control
1. IN:
The signal originating from a broadband or yagi antenna is connected at this F connector.
2. OUT:
The filter amplified signal is directly available at this F connector.
3. Convenience Outlet:
This outlet is provided to allow the chaining of amplifiers in the headend equipment rack. The polarized AC outlet is capable of delivering up
to 250 watts of AC power.
4. Power Cord:
This three prong polarized power cord is approved by both UL and
CSA for safe operation of the amplifier. Do not cut the ground terminal for both safety and operational reasons. Connect to 108 to 125
VAC, 50/60 Hz electrical outlet.

Installation
It is recommended that assistance be available to safely install equipment in equipment racks.
1. Install chassis in equipment rack (equipment rack sold separately) by supporting the bottom and rear of HSA at the desired elevation
in rack.
2 Line up the side holes of chassis with the tapped equipment rack holes.
3. Insert the provided screws through the side holes in chassis and thread into the tapped equipment rack holes.
4. Fasten the bottom screws first, then fasten top screws (tighten securely).
5. Connect a cable from the source RF signal (single channel antenna or band pass filter) to the input connector of the
6. Connect a cable from the RF output connector to the input connector of the channel combining system.
7. Connect power cord to receptacle supplying uninterrupted line power (LED on front panel will illuminate).
8. Connect a spectrum analyzer or signal level meter to a common channel point of the combining system.
9. Measure nearest adjacent channels amplitude level.
10. Adjust the RF GAIN AGC control on the front panel of the
HSA until channel carrier level is the same amplitude.
