Product Description
The MV600/2i is a two-channel, full-range Class D marine amplifier equipped with NexD2™, the second generation of JL
Audio’s high-speed switching technology. It is engineered to deliver reference-grade audio amplification with outstanding
efficiency while also incorporating unprecedented processing power. Instead of traditional analog processing controlled by
knobs and switches, MVi amplifiers feature an integrated DSP (Digital Signal Processor). The amplifier and its integrated DSP
are configured using an external device (PC, Tablet or Phone), with the appropriate JL Audio TüN™ application installed.

Cooling Efficiency Considerations
The outer shell of your JL Audio amplifier is designed to remove heat from the amplifier circuitry. For optimum cooling
performance, this outer shell should be exposed to as large a volume of air as possible. Enclosing the amplifier in a
small, poorly ventilated chamber can lead to excessive heat build-up and degraded performance. If an installation calls
for an enclosure around the amplifier, we recommend that this enclosure be ventilated with the aid of a fan. In normal
applications, fan-cooling is not necessary. When mounting the amplifier in an enclosed compartment, make sure there is at
least 1 inch (2.5 cm) of space above the amplifier’s outer shell to permit proper cooling.
Mounting Considerations
MV amplifiers are equipped with keyhole style
mounting holes to simplify installations in confined
spaces or vertical-mount applications. Mounting screws
may be preinstalled, allowing amplifier connections
to be made prior to securing in its final location. See
diagram at right.
When selecting the installation location, consider
the mounting orientation of the amplifier and its
associated connections. If possible, position the
amplifier vertically, with all connections pointing
downward. Wiring and cables should be routed to
direct potential condensation and moisture away
from the amplifier. When installed in this manner, the
amplifier achieves an IPX2 water-resistance rating.

Speaker Output Harnesses
Connect the speaker output leads to the corresponding speaker wires. These harnesses and their companion cables are
equipped with water-resistant connectors for maximum connection integrity in marine environments.
5
JLid-COMM
Connect optional accessories (MVi-HUB, M-DRC-50, VXi-BTC, MVi-DRCADAPT, etc.) to this port.
6
USB
This USB A/B port permits connection to a computer for configuration and tuning, using TüN™ Software.
7
Reset Buttons
Use a small pin to perform the following:
(A) Factory Reset (wipe memory, reboot amp)
- Press and hold the button for 7 seconds. All user settings will be
erased and the amplifier will revert to its factory settings!
(B) Reboot Amplifier
- Press and release the button. Previous user settings will be retained.
LED Status/Condition Reporting
LEDs located on the chassis top and connection panel are used to communicate amplifier status and condition. Refer to the
