Network Connection =
The RA-6000 can be attached to a network using the rear panel 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.

• TONE BYPASS: TONE BYPASS on/off (For more information refer to Tone
Control Bypass section).
NOTE: This setting is stored permanently even after the RA‑6000 is
powered off.
• BASS: BASS level can be changed to desired settings. (For more information
refer to Bass and Treble Control section.)

• TREBLE: TREBLE level can be changed to desired settings. (For more
information refer to Bass and Treble Control section.)
NOTE: This setting is stored permanently even after the RA‑6000 is
powered off.
• BALANCE: Change left/right balance (For more information on Balance
sections refer to the Balance Control section).
NOTE: This setting is stored permanently even after the RA‑6000 is
powered off.
• HT BYPASS: This option enables the Home Theater Bypass mode allowing
audio signals to be routed directly through the RA-6000 from a Surround
Sound Processor or Receiver output. Typical use is to connect the analog
output RCA Preoutput Front Left and Front Right signals from the processor
or receiver to the AUX INPUT or XLR INPUT on the RA-6000. The audio
is routed on the most direct path disabling Tone control at a unity gain
setting or fixed level to the RA-6000's amplifier circuits. To active the
Home Theater Bypass select the desired source input connection in the
setup menu then select the specified source using the front panel or remote
control. When the HT BYPASS source is selected the volume controller
is disabled allowing the volume to be controlled by the Home Theater
Processor or Receiver.
Valid settings include: Disabled (Default), AUX, XLR.
• HT BYPASS LEVEL: This option allows customization of the amplification
level used in the Home Theater Bypass mode. Select the + or - amplifier
gain levels if needed to match the home theater processor or receiver
output levels.
NOTE: Most level adjustments are done in the Home Theater Processor
or Receiver so these adjustments should only be used if the amplifier gain
output cannot be matched with the Home Theater source.
Valid settings include: 0 (default), +1 to +10, -1 to -10.
•
FIXED VOLUME:
Configures a Fixed Volume level for a specified input. To
enable this feature press the +/- buttons to select the desired fixed volume
level for Aux 1, USB, PC-USB, Optical 1, Optical 2, Coax 1, Coax 2 or
Bluetooth. When enabled and the input with a Fixed Volume is selected,
the Volume level will immediately be set to the specified level.
Valid settings include: VARIABLE, FIXED 01-95, FIXED MAX.
• AUX1 VOL: VARIABLE (disabled) is factory default.
• USB VOL: VARIABLE (disabled) is factory default.
• PC-USB VOL: VARIABLE (disabled) is factory default.
• OPT1 VOL: VARIABLE (disabled) is factory default.
• OPT2 VOL: VARIABLE (disabled) is factory default.
• COAX1 VOL: VARIABLE (disabled) is factory default.
