WS-2220 BT 4-Zone Level Controller with Bluetooth

The WS-220 BT is a 4 Zone level controller with built in Bluetooth. Utilizing the CSR BT 4.0 with AptX codec for the highest sound quality available. Main and Auxiliary inputs built in as well for true 3 source selection all housed in a one half DIN chassis. Using our exclusive design which allows the independent control of 4 zones which can be assigned to any audio components in a system. For instance, Zone 1 could be set up for Tower Speakers, Zone 2 could be used for Front Cabin Speakers, Zone 3 could be Rear Cabin Speakers, and Zone 4 could be Subwoofer(s). Levels can be set for each of these zones independently, then the Master allows overall control of all 4 zones. The WS-220 BT includes a talk back microphone with its own independent level control, allowing the adjustment of the microphone level independently of the music. The talk back microphone can be used to broadcast a voice over long distances – similar to a public address system. When the talk button on the microphone is pressed, music is automatically muted on Zone 1 and the microphone audio is broadcast over Zone 1. When the microphone talk button is released, music returns to the previous level.

1. Master Level. This controls the overall volume of the system – overriding all zones with the exception of the Mic level control.

2. Zone 1. This controls the level of whatever amplifier is connected to it. Microphone audio is broadcast on this zone only, so it is suggested that this zone be used for Tower Speakers. The Master Level control overrides this zone control.

3. Zones 2-4. These control whatever amplifiers are connected to them. These zones are equal in operation, so they can be assigned in any way needed. The Master Level overrides all these zones.

4. Mic. This controls the level of the microphone when the talkback button is pressed. Mic level is unaffected by the Master level control.

5. Source. Allows switching between Main (head unit), Auxiliary (wired audio device), or
Bluetooth enabled wireless device.

6. Auxiliary Input. 3.5 mm input jack for MP3 player or additional wired audio source.

7. Boat Link. 3.5mm output jack. For linking with other WS-220BT, WS-420BT/SQ
equipped systems.

8. Microphone Input. This is where the included talk back microphone should be
connected.

9. Input Gain.
9(a) Main input sensitivity adjustment.
9(b) Aux input sensitivity adjustment.
9.(c) Bluetooth input sensitivity adjustment. These are to properly match the inputs of the WS-220 BT to the outputs of the sources connected.
NOTE: If you are not an experienced installer, it is recommended to leave these adjustments in the preset factory position.

10. Illumination. WS-220 BT comes preset in blue illumination mode. If red is preferred, set this switch to the position marked “RED”.

11. Ground Isolation. If alternator whine appears in the system, the jumper position can be changed to even the grounding levels and eliminate the noise. Be sure the system is off before adjusting the jumper!
