INSTALLATION NOTES:
• High or low impedance speaker connection options can be
selected independently for each output channel via the
amplifier configuration web interface.
• Analog input sensitivity can be adjusted independently for each
channel via the amplifier configuration web interface.
•S/PDIF digital audio I/O routing can be configured via the
amplifier configuration web interface.
• GPIO (General Purpose Input/Output) options can be configured
via the amplifier configuration web interface.
• Ensure that rack or other confined installation does not restrict
the airflow required for safe and reliable operation of the
equipment. It is important to ensure that the 40°C (104°F)
maximum operating temperature for the equipment is not
exceeded.
WIRELESS NETWORK CONTROL CONNECTION:
WIFI: A mobile, laptop or desktop device with WiFi functionality
and a web browser is required. Follow the steps below.
1. Connect the DLC amplifier to mains power using the supplied
mains cable and wait for the front panel WiFi indicator to
illuminate green.
2. Use a mobile, laptop or desktop device to search for available
WiFi networks. Connect to, ‘Theory (product serial number)’
using the password, ‘password’. The amplifier serial number
can be found on its rear panel.
3. Open a mobile, laptop or desktop device web browser and
enter the following IP address: 192.168.4.1. The amplifier
configuration web interface page will open in the browser
app to enable amplifier configuration as required.
It is strongly recommended that the DLC amplifier WiFi password
is changed following initial wireless connection.
WIRED NETWORK CONTROL CONNECTION:
ETHERNET: A laptop or desktop device with Ethernet
functionality, a web browser and a network scanning app is
required. Follow the steps below.
1. Connect the DLC amplifier Network Control Ethernet jack to a
free jack on a network router or network switch using an
Ethernet cable.
2. Connect the DLC amplifier to mains power using the supplied
mains cable and wait for the front panel Network indicator
to illuminate green to indicate that the amplifier has been
assigned an IP address.
3. Use a network scanner app to identify the IP address assigned
by the network router to the DLC amplifier.
4. Open a laptop or desktop device web browser and enter the
IP address identified in the Step 3 above. The amplifier
configuration web interface page will open to enable amplifier
configuration as required.

5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any ventilation opening. Install in accordance with the
manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat registers,
stoves, or other apparatus (including amplifiers) that produce heat.
9. To reduce the risk of electrical shock, the power cord shall be
connected to a mains socket outlet with a protective earthing
connection.
10. Do not defeat the safety purpose of the polarized or grounding type
plug. A polarized plug has two blades with one wider than the other.
A grounding type plug has two blades and a third grounding prong.
The wide blade or the third prong are provided for your safety. If the
provided plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
11. Protect the power cord from being walked on or pinched particularly
at plugs, convenience receptacles, and the point where they exit from
the apparatus.
12. Do not unplug the unit by pulling on the cord, use the plug.
13. Unplug this apparatus during lightning storms or when unused for long
periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required
when the apparatus has been damaged in any way, such as power
supply cord or plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has been exposed to rain
or moisture, does not operate normally, or has been dropped.
15. The appliance coupler, or the AC Mains plug, is the AC mains
disconnect device and shall remain readily accessible after installation.
FCC COMPLIANCE:
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including
interference that may cause undesired operation.
Note: This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates uses
and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications.
However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference
to radioor television reception, which can be determined by turning
the equipment o and on, the user is encouraged to try to correct the
interference by oneor more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit dierent from that
to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
