Welcome to PHONOPREAMPS.COM on This A/V switcher allows the addition of up to four composite video or S-Video sources to your TV or A/V receiver. Output is provided via both composite or S-video signals. This is for use with analog NTSC video (used in the USA) and is not compatible with SECAM or PAL. $24.50 plus shipping This stereo A/V switcher features four A/V inputs; three on the rear and one up front. All of these have both composite and S-video jacks, as does the rear panel output jack set. Unlike our other A/V switcher, this model also features a built-in RF modulator with channel 3/4 output; thus it can be used with any analog TV, even one unequipped with video inputs. This model features auto-power on; it senses whether the input selected actually carries a video signal, and shuts itself off when none is present.
