WARNING: Do not connect any RCA cables to the ZEN-F interface or additional processors prior to properly grounding aftermarket amplifier(s)!

Overview

The NAV-TV ZEN-F processor seamlessly converts Ferrari Portofino factory MOST-150 audio bus to 12-channel analog RCA and TOSLink output. Adding aftermarket amplifiers to the OE Ferrari system has never been so simple. This kit integrates with the OEM M.O.S.T.® bus to retain volume control, full fade (and balance: analog only), treble, mid-range & Bluetooth voice calls with no external speaker (true OEM integration). NOTE: OEM radio systems not equipped with a fiber optic amplifier are not compatible.

ZEN-F Installation

If this vehicle has a factory amplifier, it must be removed and the ZEN-F can be installed in its place. If this vehicle is not amplified from the factory, it is not compatible with the ZEN-F.
Connect the following wires from the provided power harness:
ZEN-F pin| Color| To vehicle:
---|---|---
1| Yellow| 12v (+) Constant
3| Violet| –Reserved, NOT USED–
4| Black| Ground (-)
6| Blue| 12v (+) remote output*

*This remote wire must be used for the aftermarket amplifier remote for proper functionality. If installing more than one amplifier/DSP, a relay must be used for reliable turn-on (500mA max).

Before connecting power to the ZEN-F, adjust dip-switch settings for the desired options:
| Time Alignment| Attenuation| TOSLink DownMix| Loudness| Vehicle Settings
---|---|---|---|---|---
Position| DIP 1| DIP 2| DIP 3| DIP 4*| DIP 5| DIP 6
UP
(off)| Front Row| Full Scale
output (0 dB)| Not used| Loudness OFF| Keep in
factory
default
DOWN
(on)| Driver-Focused| -12 dB output| Not used| Loudness ON
If using analog RCAs for the 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!

5. If using TOSLink for the signal to the amplifier, connect the cable to the TOSLink port shown on page 2.
NOTE: both Analog and Digital output sound simultaneous, regardless of which type is used.

Connect the provided MOST Fiber Cable from the (previously removed) amplifier, or from the radio’s fiber port to the MOST port on the ZEN-F.

ZEN-F General Installation Notes

This interface can only be installed in vehicles with a factory MOST fiber optic amplifier.
1. The factory amplifier must be removed. Connect the OEM fiber previously connected to the amp, directly into the ZEN-F.
Tuning tips:
1. Before beginning the 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.
From the factory, some vehicles’ audio will attenuate when in reverse. Simply set the ‘reverse volume’ to the desired level while in reverse to adjust this. The ZEN-F will retain its method. The same is true for NAV guidance audio and BT voice calls.

FAQ

For installations with this ZEN processor, make certain that any added amplifier’s ground resistance (reference vehicle battery ground) does not exceed 1 ohm.
If you’ve installed a third-party DSP (receiving a signal from the ZEN, before the amplifier) and you’re having issues with audio bleeding from one channel to another, choosing Bluetooth phone calls, or any other signal processing issues, rule out the ZEN first by temporarily bypassing the third-party DSP and running signal directly from he ZEN to the amplifier(s) and verify the problem still exists before calling technical support.
