CE Labs Amp-400 Distribution Amplifier distributes the Audio and Video signals from one home theater source to up to 4 other components. A Distribution Amplifier such as the Amp-400 is necessary when splitting the A/V signals from a component to feed multiple devices. The Audio Video signals also known as line-level or composite become degraded when split using a simple RCA-type Y adapter. The Amp-400 maintains a proper level of impedance to each output providing a crisp picture. The Amp-400 is ideal for splitting the signals from a DVD player or DSS receiver and feeding the signals to multiple TVs / monitors or VCR s for recording. Daisy chain several units for larger displays with great picture quality. Heavy duty metal housing provides excellent shielding. Allows up to 150 ft. runs. Save the expense of additional A/V receivers.
