1. For ZEN-A2B installations, the factory amplifier must be removed and the ZEN-A2B can be installed into

its place. If this vehicle is not amplified from factory then this interface is not needed.

2. After locating the factory amplifier, disconnect it entirely as it will no longer be in use. With the vehicle

off, connect the provided ZEN-A2B harness to the (previously removed) OEM amplifier connectors

(gray & black). Below is a pin out chart (just for reference):

3. Connect the OEM A²B® (USB)

connector removed from the OEM

amplifier to the A2B IN port on the

ZEN-A2B.

4. Connect the blue wire (PIN 2) to the remote input on the amplifier*.

*If installing more than one amplifier/DSP, a relay must be used for reliable turn-on (ZEN remote output: 500mA max).

*Remote wire note: the (blue) remote wire will output 12v as soon as CAN wakes (door opens, etc).

For ZEN modules with 3.0.12 firmware and up (units built past 09/16/18), the

dip switches are no longer used. Use the ZEN online configuration tool to

adjust tone levels, fader, etc. See pages 7-8 for more information on this tool.

Open a browser and type in zen.local/. Connect via the USB to adjust desired

settings

6. If using analog RCAs for signal to the amplifier, connect according to the reference chart below.

WARNING: Do not connect RCA cables to this interface until all amplifiers/external processors are

properly grounded. Failure to do this may cause damage to the interface and VOID the warranty!

7. If using TOSLink for signal to the amplifier, connect the cable to the TOSLink port shown on page 2.

NOTE: both Analog and Digital output sound simultaneously, regardless of which type is used.

• Tuning tips:

1. Before beginning tuning process (especially with external EQ/Processors), set Bass & Treble on

the head unit for each source to flat (0).

2. Begin with amplifier/EQ gains all the way down.

3. With dynamic music playing, adjust the radio volume to maximum.

4. Adjust the amplifier/EQ gains to desired maximum level.
