Setup

Rack Mounting

The RCS350-6 amplifier is 19-inch rack-mountable. To install it into a rack, attach the included rack ears to the sides of the amplifier using the provided screws. Ensure the holes on the rack ears align with the screw holes on the amplifier chassis. Handles can also be attached to the rack ears for easier handling.

Speaker Wiring (70V Parallel Wiring)

The RCS350-6 supports 70V, 100V, 8 Ohm, and 4 Ohm speaker configurations. For 70V/100V systems, speakers are wired in parallel. This means connecting the positive terminal of one speaker to the positive terminal of the next, and the negative to the negative, forming a daisy chain. The last speaker in the chain connects to the amplifier.

Each 70V speaker includes a built-in transformer (tap) that allows you to select the wattage drawn from the amplifier. Ensure the total wattage drawn by all speakers in a zone does not exceed the amplifier's wattage capacity per zone (100W per zone for RCS350-6).

Zone Setup

The amplifier features 6 independent zones, each with its own volume control. This allows you to distribute audio to different areas (zones) and control their volume levels separately. For example, Zone 1 could be a dining area, Zone 2 a bar, and so on. Each zone can handle a maximum of 100 watts.

Microphone Usage

MIC 1 on the front panel is a priority microphone, meaning it will automatically lower the volume of other audio sources when spoken into. The mute level knob on the rear panel adjusts how much the other audio sources are attenuated. MIC 2 and MIC 3 inputs on the rear panel are affected by the echo controls.

Bluetooth/USB/SD Playback

To play media from a USB drive or SD card, insert the device into the corresponding slot on the front panel. Use the mode button to select the input source. For Bluetooth, select Bluetooth mode, then pair your device with "RCS350-6" from your device's Bluetooth settings. Use the playback controls on the front panel or the remote control to manage your media.

FM Radio

Extend the FM antenna on the rear panel to improve radio reception. Use the mode button to select FM radio and the playback controls to tune stations.

Remote Control

The included remote control allows you to manage various functions of the amplifier, including power, mode selection, volume, playback controls, and EQ settings.

Maintenance

To ensure optimal performance and longevity of your Rockville RCS350-6 amplifier, follow these maintenance guidelines:

• Keep the amplifier in a well-ventilated area to prevent overheating. Ensure the cooling fan is not obstructed.
• Regularly clean the exterior with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
• Check all cable connections periodically to ensure they are secure and free from damage.
• Avoid exposing the amplifier to moisture, extreme temperatures, or direct sunlight.

Troubleshooting

If you encounter any issues with your Rockville RCS350-6 amplifier, refer to the following troubleshooting tips:

• No Power: Ensure the power cable is securely connected and the power switch is in the ON position. Check the power outlet and the amplifier's fuse.
• No Sound: Verify all speaker connections are correct and secure. Check input source selection and volume levels (master, zone, and individual input volumes). Ensure speakers are properly tapped for 70V/100V systems.
• Distorted Sound: Lower the volume levels to prevent clipping. Check speaker impedance and wattage taps to ensure they are within the amplifier's limits. Inspect speaker wires for damage.
• Bluetooth Connection Issues: Ensure the amplifier is in Bluetooth mode and your device's Bluetooth is enabled. Try unpairing and re-pairing the device. Move your device closer to the amplifier.
• Microphone Not Working: Check microphone connections and ensure the microphone volume is raised. If using MIC 1, ensure the mute level is adjusted correctly.
