LAST ON, FIRST OFF! – To avoid potential
loud pops and/or hum, always turn on the
amplifer last after other components such
as pre-amps and sources and turn off the
amplifer first when powering down.
Normal Operation
Observe these simple guidelines during normal operation:
Source Material: Your Acurus amplier will sound only as
good as the source material it is amplifying. We recom-
mend CD-quality or higher bitrate sources in order to
experience the full capabilities of your new amplier.
You’ll probably nd that MP3 or other lossy, compressed
(less than 256Kbps bitrate) source audio lack the detail
and denition that your Acurus components are capable
of delivering.
Break In Period: While we burn-in each unit at the fac-
tory before it is shipped, we recommend playing your
amplier a minium of 24 hours before performing any
critical listening.
When not in Use: We do not recommend leaving the
amplier on continuously as a means of somehow
improving it’s long-term reliability or sonics. As with
prior Acurus designs, we’ve designed the A2000 series
ampliers to come up to operating temperature in a few
short minutes and have chosen components that can
handle temperature cycles well beyond the intended life
of the product.
We can minimize electric utilization and preserve our
global environment by taking advantage of the low-pow-
er standby mode these ampliers offer.
Acurus’ Proprietary Enhanced
Ethernet Control (E2C)
Enhanced Ethernet Control allows the user or installer to
quickly and easily control and monitor the status of Acu-
rus components over a home network. For the A2000
series ampliers, this capability provides a useful setup
and diagnostic tool.
Setting up Enhanced Ethernet Control (E2C): To enable
E2C, the amplier must be connected directly to a net-
work router or switch as indicated by the green network
activity LED on the rear panel of the amplier. After a
couple minutes connected to the network, the amplier
network module will be initialized and the amplier will
be controllable as a network device.
Any networked computer, smartphone or tablet con-
nected to the local network and running up-to-date web
browser software may be used to control and monitor
the amplier. To access the control page of the amplier,
the amplier’s IP address must be typed in the browser
URL line of the controlling device.:
Because most network routers default to allow DHCP
(service running on the router) to automatically assign
IP addresses to network devices, it is necessary rst to
discover the specic IP address assigned to the ampli-
er by the network router. There are a few common
methods to accomplish this.
Manual Network Discovery: Below are several methods
that can be used to discover an Acurus A2000 series
amplier on a local network. The critical information
for identifying the Acurus component is that the A2000
series mac address always is formatted with the rst 3
pairs of numbers constant as:
MAC Address 00:03:75:XX:YY:ZZ
