Rear USB Power Port
]
The rear USB port provides 5V/0.5 amps for charging or powering
USB devices including streaming music players. This port does not allow
playback of audio.
The port can be congured to remain powered even when the RA-1572
is in standby mode through the front panel setup menu (See USB POWER
on page 16).
This conguration option allows the attached streaming source to remain
powered for use with the Signal Sense function for automatic power on/
off control of the amplier.
NOTE: When congured to provide continuous power to the rear panel
USB port the RA‑1572 will consume additional power even when in
standby mode.

A properly setup high-performance audio system produces the most natural
sound with little or no adjustment of the tone controls. Use these controls
sparingly. Be particularly careful when turning the controls up as this
increases the power output in the bass or treble range, increasing the load
on the amplier and speakers.
NOTE: Setting the Bass and Treble controls does not automatically turn
on the tone control. To turn on tone control, refer to previous section
Tone Control Bypass.
