DESCRIPTIONspecifications
The Extron PA 300 Peaking Amplifier offers an RGB video bandwidth of 350 MHz
Variable gain control compensates for voltage variances, and allows sharp, bright image reproduction from virtually any signal source. Independent controls for low frequency and high frequency peaking compensate for smearing and detail loss, respectively, for superb image reproduction without regard to cable length or type.
The PA 300 restores the low level sync voltages found on many computers, as low as 1.8 volts, to normal TTL levels. This sync restoration prepares the signals to run down long cable runs and offers enhanced compatibility with a wide range of computers, display devices, and cable types.
Features
n350 MHz
nDrives high resolution signals long distances – Capable of driving RGB video signals up to 600 feet (185 meters) with Extron MHR or similar cable, and up to 1,000 feet (300 meters) with Extron RG6 or similar cable
nVariable gain – Boosts overall signal voltage level to maintain image brightness and compensate for voltage losses due to cable resistance.
nSeparate low frequency and high frequency peaking – Eliminates low frequency image smearing, improves high frequency detail by compensating for losses due to cable capacitance
nRestores sync to TTL level – Ensures that the monitor or projector accurately locks to sync and displays a stable image
