The FP-PA20 is part of the group of versatile FLAT-PAK products from Radio Design Labs. The unique FLAT-PAK case can be directly screwed or bolted to cabinets or shelves. Optionally available rack-mounting accessories permit single or multiple FLAT-PAK module mounting.

APPLICATION: The FP-PA20 is the ideal choice in many applications where a high quality utility amplifier is needed to drive an 8 ohm speaker.

The FP-PA20 features a balanced line level input that may be connected unbalanced. A front panel gain control is designed to be adjusted either manually or with a trimming screwdriver. The gain range will accommodate standard unbalanced levels as well as professional balanced levels. The output will drive an 8 ohm speaker or multiple speakers connected to present an 8 ohm load to the amplifier.

A red PEAK LED is provided to indicate the threshold of the integral compressor. Audio levels that could cause the amplified output to clip are compressed according to two dynamic time constants. Normal audio level signals remain unaffected by the compressor thereby preserving audio dynamics and preventing the compressor from increasing feedback potential when the amplifier is used for paging. The compressor is designed to remain aurally transparent while maintaining clean, unclipped amplified audio for input overloads of up to 20 dB. The FP-PA20 produces average audio levels and audio clarity normally expected of amplifiers delivering much higher output power.

The durable construction and low profile of the FP-PA20 allow mounting in a wide range of locations not suited to a conventional style power amplifier. Power is provided to the module either through the barrier block or through the DC power jack. For full RMS output power, a 24 VDC 2 Amp power supply is required. A 1 Amp supply is sufficient for normal program audio levels and content. Power supplies are sold separately.

Wherever a high quality audio power amplifier is needed to provide reliability, compactness and unsurpassed versatility, the FP-PA20 is the ideal choice. Use the FP-PA20 individually, or combine it with other RDL products as part of a complete audio/video system.

SOUND LIKE YOU HAVE NEVER SEEN IT BEFORE!

SoundPads stick-on speakers convert and transfer sound to most high density thin walled surfaces you put them on. Converts poster art, bookcases, thin tables, door panels and ceiling tiles into permanent stereo speakers. You cannot get a better quality speaker for the price.

Sound quality will vary from excellent to awesome depending on the surface you peel and stick them on. SoundPads let you literally feel the sound. They will blow your mind!

Simply connect them as you would any conventional speaker to your existing stereo using the amplifier or tuner.

The Video Distribution Amp is a signal booster and splitter that is used to take video input from a single source and direct it to four video outputs for monitors using analog signals. The signal boost obtained by using the VS94A allows you to not only split the signal but to extend the distance so that you can send the signal to about 210 feet. (Your average VGA card, combined with a standard VGA cable, can send a clear VGA signal approximately 25 feet.)
