RS232 u
The RA-1572MKII can be controlled via RS232 for integration with
automation systems. The RS232 input accepts a standard straight DB-9
Male-to-Female cable.
For additional information on the connections, software, and operating codes
for RS232 control of the RA-1572MKII, contact your authorized Rotel dealer.
Rotel Link o
Rotel Link is not used for RA-1572MKII.
EXT REM IN Jack p
This 3.5mm mini-jack receives command codes from industry-standard infrared
receivers via hard-wired connections. This feature could prove useful when
the unit is installed in a cabinet and the front-panel sensor is blocked. Consult
your authorized Rotel dealer for information on these external repeaters and
the proper wiring of a jack to fit the mini-jack receptacle.
Network Connection t
The RA-1572MKII can be attached to a network using the rear panel
t
NETWORK socket
. The NETWORK configurations allow both STATIC
and DHCP IP addressing. See the Network section of this manual under
Setting Menu for IP address configuration information.
The NETWORK connection allows software updates to be downloaded from
the Internet. The NETWORK connection also allows IP control for integration
with automation systems.
For additional information on the IP control please contact your authorized
Rotel dealer.
Protection Circuit
The amplifier has both thermal and over-current protection circuitry that
protects the amplifier against damage in the event of extreme or faulty
operating conditions. The protection circuits are independent of the audio
signal and have no impact on sonic performance. Instead, the protection
circuits monitor the temperature of the output devices and shut down the
amplifier if temperatures exceed safe limits.
Most likely, you will never see this protection circuitry in action. However,
should a faulty condition arise, the amplifier will stop playing and will
display "AMP PROTECTION" on the front panel.
If this happens, turn the amplifier off. Let it cool down for several minutes,
and attempt to identify and correct the problem that caused the protection
circuitry to engage. When you turn the amplifier back on, the protection
circuit will automatically reset.
In most cases, the protection circuitry activates because of a fault condition
such as shorted speaker wires, or inadequate ventilation leading to an
overheating condition. In very rare cases, highly reactive or extremely low
impedance speaker loads could cause the protection circuit to engage.

If the protection circuitry triggers repeatedly and you are unable to isolate
and correct the faulty condition, contact your authorized Rotel dealer for
assistance in troubleshooting.

• POWER ON MAX VOLUME: This sets the maximum volume level when
the unit is turned ON. "45" is the factory default.
NOTE: Power On Max Volume settings do not apply to sources
configured with Fixed Gain.
• POWER OPTION: Enables the RA-1572MKII to be controlled via the network
port when attached to an automation system. The power consumption is
higher in Quick Power mode. If network control is not required select the
Normal Power mode. "Normal" is the factory default.
Valid settings include: Normal, Quick.
NOTE: When the POWER OPTION is configured to Quick, the
RA‑1572MKII will consume additional power in standby mode.
NOTE: Due to local power consumption regulations the POWER
OPTION function is not available in all markets.
• USB POWER: This option allows the rear panel USB connector to provide
power, even when the RA-1572MKII is in standby mode.
