Model 515 Video/Audio Switching System
Installation and Operation Instructions
Description and Application
The Model 515 is a high-performance switching system designed for video components. It offers an economical and convenient method to switch between up to five video sources, each with line-level composite video and stereo audio outputs. Compatible products include TV tuners, video disc players, satellite receivers, and VCRs. The selected video/audio signal is outputted by the 515 without alteration from its passive circuitry, ensuring no crosstalk or video bleed-through from unselected components.
The 515 can also switch the Radio Frequency (RF) output of video components, typically on channel 3 or 4, for use with televisions that lack direct video and audio inputs. Note that a single 515 unit cannot switch both RF and line-level signals simultaneously.
Designed for ease of placement, the 515's compact size allows it to sit on a shelf (freestanding), be fastened to a surface (cabinet-mounted), or be flush-mounted via the front panel. A Model 515V variant is available for applications requiring a vertical front panel orientation.
Feature Summary
- 5 Inputs : 1 Output configuration for selecting the line-level output of one of 5 video components.
- Optional selection between Radio Frequency (RF) signals modulated over TV channels 2-4.
- Constructed with first-quality parts and design for dependable, long-term service.
- Features passive circuitry and extensive signal shielding for high signal integrity.
- Offers three cabinet mounting configurations for flexible placement options.
Installation
Choose a convenient location for the 515, considering the placement of the video components it will connect to and the necessary cable routing paths.
The 515 can be placed on any flat surface, such as a shelf or on top of another component. For more permanent installations, the 515 can be secured using one of two mounting methods.
Cabinet Mounting
The Model 515 features a metal cabinet with "keyhole style" slots, enabling it to be secured to most flat surfaces using two #6 x 3/4" flat head screws. Follow these steps:
- Use the provided template to mark the location for the two mounting screws at the designated "crosshairs." Ensure sufficient space is left on the rear of the cabinet to access the jacks.
- Drive the mounting screws into the surface, leaving approximately 1/4 inch of the screw head exposed.
- Position the larger diameter portion of the keyhole slots over the screw heads, then slide the cabinet back to secure it in place.
- If necessary, adjust the gap between the screw head and the mounting surface to ensure a snug fit.
Panel Mounting
The Model 515 can also be flush-mounted, concealing its cabinet and connecting cables behind a fixture. For this method, use the provided template to identify a suitable location and the required cutout for the 515's cabinet. The template indicates a rectangular cutout of 1-7/8 inches (48mm) by 7-1/8 inches (180mm).
- Mark and cut the specified rectangular opening in the fixture's surface.
- Remove the rubber feet from the 515 cabinet if necessary, and insert the unit into the cutout.
- Devise a method for securing the 515 from behind the fixture, such as using common L-brackets.
Connections
All connections for the Model 515 are located on the rear panel and utilize standard RCA audio/video patch cords. For custom cables, use high-quality video/audio transmission cable and connectors.
Line-Level Connections
- Connect the composite video outputs from up to five video components to the 515's rear panel jacks labeled VIDEO 1-5.
- Connect the respective pairs of audio outputs to the 515's AUDIO 1-5 jacks.
- Connect the 515's VIDEO OUTPUT and stereo AUDIO OUTPUTS to the line-level inputs of the destination video component.
Radio Frequency (RF) Connections
When switching RF outputs from video components, connect them to the rear panel jacks marked VIDEO 1-5. Connect the 515's VIDEO OUTPUT jack to the VHF antenna input of a television set or video tuner. Use 75-ohm coaxial cable (RG-59 or equivalent) with good quality RCA plugs or adapters for the connection to the 515.
Important: Do not attempt to route both line-level video/audio and RF signals through the same 515 unit.
Operation
The 515 is designed for extreme simplicity of use. Its entirely passive circuitry means there is no On/Off switch. Pressing a front panel push-button selects the desired product for playback. Selecting a new product automatically disconnects the previously selected one.
Testing
After completing all connections, test the 515's operation by selecting each of the five video product sources individually. If connections are made correctly, selecting a source component should yield video and audio performance comparable to a direct connection. The 515 is engineered to route the selected video source with minimal loss, distortion, or signal degradation.
Troubleshooting
Most issues encountered with the 515 can be attributed to the cables connecting it to the video products. If problems arise, first inspect for defective patch cables or incorrect connections. For instance, if no picture is displayed for any selected video product, check the connection between the 515's VIDEO OUTPUT and the destination video product's inputs. If an issue appears specific to only one of the five source products, verify the connections between that product and the 515.
