REFERENCE404s Amplifier Fuse Values
CIRCUIT BREAKERS/FUSES
EXTERNAL
Like all audio components, the REFERENCE404s amplifier must be fused
near the battery. A fuse or circuit breaker must be located within 18” of the
battery. This will prevent a fire in the event of a shorted cable. See the chart
below to determine the correct fuse value.
INTERNAL
The REFERENCE404s amplifier is fused with automotive-type fuses. In the
event of blown power supply fuses, the “Fault” indicator on the front panel will
light. The fuses are accessible via a plastic plug on the bottom of the
amplifier. See the chart below to determine the fuse value. Never replace
the fuses with a higher value than what is supplied. This may result in
amplifier damage and will void the warranty!

REMOTE TURN-ON
Connect the “Remote” to the turn-on lead from the source unit. When +12
volts is received, the amplifier will turn on.
SIGNAL CABLE
Use a high-quality cable that will be easy to install and has minimal signal loss
to guarantee optimum performance. Soundstream’s DL1 and SL1 are
ideal.
SPEAKER CABLE
The REFERENCE404s amplifier will accept up to 8 gauge speaker cable. Use
a high quality, flexible, multi-strand cable for best performance and longevity.
