ZEN-A2B Interface
NTV-ASY272
ZEN RCA Harness
NTV-HAR315
NOTE: All vehicles require SYNC3, this
interface only applies to vehicles equipped
with A²B® (B&O or Revel Amplifiers)
The ZEN-A2B processor seamlessly converts 2018+ Ford factory A²B® (Automotive Audio Bus) to 12-channel
analog RCA and TOSLink output. Adding aftermarket amplifiers to the OE B&O or Revel amplified SYNC3
system has never been so simple and seamless. This kit integrates with the OEM A²B® bus to retain volume
control, full fade and balance (analog only), treble, mid-range, bass control & Bluetooth voice calls with no
external speaker (true OEM integration). NOTE: 2018 vehicles not equipped with a factory B&O or Revel
amplified system are not equipped with A²B®bus and do not require this interface.

WARNING: Due to the complexity and sensitivity of the OEM Ford A²B®, the ZEN-
A2B must be used with amplifiers that are grounded directly to the battery. The
resistance to (true battery) ground of the Amplifier(s) must not exceed 1 ohm,
otherwise you will likely experience performance issues with the ZEN-A2B.

Wire Side
(HAR325)
*If installing more than one amplifier/DSP, a relay must be used for reliable turn-on (ZEN output: 500mA max).
*Remote wire note: the ZEN-A2B (green LED) will turn on after the car is unlocked, but the blue remote wire will not
output 12v until the key and radio are ON.
*When DIP 3 is ON, front and rear chimes mixed into TOSLink output
**When DIP 5 is ON, factory chimes are stripped from all other channels, including TOSLink.
ZEN-A2B Installation
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*.
5. Adjust dip-switch settings for the desired options:
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!

ZEN-A2B General Installation Notes
•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.
