    • Allen Avionics HD-SDI-5R 5-Channel Isolated SDI & HD-SDI Serial Digital Video Hum Eliminator

      Allen Avionics HD-SDI-5R 5-Channel Isolated SDI & HD-SDI Serial Digital Video Hum Eliminator

      Even though SDI is more immune to extraneous noise and low frequency components (hum) problems can still exist. As with analog signals, once you have noise in the signal, it is extremely difficult and costly to remove. Jitter caused by induced noise effects can compound problems created by unstable signal sources, poor re-clocking systems, cable attenuation and can be the demise of digital signals. HD-SDI Serial Digital signal transmissions at 1.485Gbps over a cable contain a range of low to high...

    • Allen Avionics AGL-10K Audio Ground Loop Isolation Transformer

      Allen Avionics AGL-10K Audio Ground Loop Isolation Transformer

      The Allen Avionics AGL-10K is an audio ground loop isolation transformer. All transformers in the AGL series are true isolation transformers, designed for low distortion, linear phase response and excellent pulse fidelity. This is accomplished by extending the bandwidth to over 300 KHz (10 - 15 times the normal 20 KHz bandwidth). The extended bandwidth guarantees a linear phase response that provides distortion-free audio with no loss of its original harmonic content. The AGL-600 and AGL-600-2...

    • Allen Avionics DELAY BOX Video & Audio Delay Line

      Allen Avionics DELAY BOX Video & Audio Delay Line

      The Master Delay Box is designed to restore perfect lip-syncing to the audio output from your digital satellite receiver and DVD-player. Modern displays, such as plasma screens, LCD screens and projectors use sophisticated imaging processors to produce the best picture possible. This processing takes time and produces a delay in the picture display. This is called a lip-sync error. This is particularly noticeable in speech, where the voice comes first and the lips move after. Lip-syncing anomalies...
