Connections

Connections for all compatible audio signal formats are described in this owner’s manual. Please select the types of connections suited for the equipment you are connecting. With some types of connections, certain settings must be made on the POA-3012CI. For details, refer to the instructions for the respective connection items below.

NOTE

• Do not plug in the power cord until all connections have been completed.
• When making connections, also refer to the operating instructions of the other components.
• In the case of Bus input/output connections, be sure to connect the left and right channels properly (left with left, right with right).
• Do not bundle power cords together with connection cables. Doing so can result in humming or noise.

Preparations

Before Connecting

The POA-3012CI incorporates six sets of 2-channel amplifiers from ZONE1 to ZONE6. The same audio signal can be output from all ZONE or separate signals can be output from each ZONE. The POA-3012CI also supports BRIDGED output. Before making the connections, determine the input signals and output signals for each ZONE and then set up the POA-3012CI in accordance with the following procedure.

Cables Used for Connections

Select the cables according to the equipment being connected.

Audio cables

Signal direction

Speaker Connections

Connection Method When Outputting 2 Channels From One ZONE

Connection Method for BRIDGED Output

• In BRIDGED mode, one channel is output from one ZONE.
• To set BRIDGED mode, select “BRIDGED” as the “OPERATION MODE” on the “Main Setup” menu.
• When BRIDGED outputs a signal input to the AUDIO INPUT terminal, input to an even-numbered input terminal.
• To select a signal for BRIDGED output from among the signals (“L”, “R”, “L+R”) input to the BUS INPUT terminal, use “INPUT SELECT” on the “Main Setup” menu.

Connecting the Speaker Cables

Carefully check the channel numbers and + (red) and – (black) polarities on the speakers being connected to the POA-3012CI, and be sure to interconnect the channels and polarities correctly.

1. Peel off about 0.03 ft/10 mm of sheathing from the tip of the speaker cable, then either twist the core wire tightly or terminate it.
2. Turn the speaker terminal counterclockwise to loosen it.
3. Insert the speaker cable’s core wire to the hilt into the speaker terminal.
4. Turn the speaker terminal clockwise to tighten it.

When using a banana plug (for the North American model)
Tighten the speaker terminal firmly before inserting the banana plug.

NOTE

• Use speakers with an impedance of 4 to 16 Ω/ohms. Use a 8 to 16 Ω/ohms speaker for BRIDGED output.
• Connect the speaker cables in such a way that they do not stick out of the speaker terminals. The protection circuit may be activated if the core wires touch the rear panel or if the + and – sides touch each other ( “Protection circuit”).
• Never touch the speaker terminals while the power supply is connected. Doing so could result in electric shock.

Protection circuit
If speakers with an impedance lower than specified (for example 4 Ω/ohms speakers / NORMAL MODE) are used for an extended period of time with the volume turned up high, the temperature may rise, activating the protection circuit. There are 2 kind of protection circuits in POA-3012CI.

1. Protection circuit for individual Amplifier (Zone 1 ~ 6) This protection circuit detects over load condition of the amplifier circuit. When the protection circuit is activiated, the speaker output of individual Amplifier (Zone 1 ~ 6) is shut off, and the Zone operation mode indicator for protected Zone No. flashes red. If this happen, unplug the power cord, then check the speaker cable and input cable connections.
2. Temperature rise protection circuit in the chassis. This protection circuit detects temperature rising in the chassis. When the protection circuit is activiated, the power source for all Amplifier circuits is shut off, and the power indicator flashes red. If this happen, it may be extremely hot in the chassis, unplug the power cord. Wait for it too cool off and improve ventilation around it.

Once this is done, plug the power cord back in and turn the set’s power back on. If the protection circuit is activated again even though there are no problems in the ventilation around the set nor in the connections, the set may be damaged. Turn the power off, then contact a DENON service center.

Input Connections

BUS INPUT Connections

• To play signals input to the BUS INPUT terminal, select the channel using “INPUT SELECT” on the “Main Setup” menu.
• When “BUS L+R” is used, signals input to BUS INPUT L and R are mixed and output as monaural.

Signals input from the BUS INPUT are output from the BUS OUTPUT terminal. These signals can be output to the BUS INPUT terminal of another POA-3012CI unit.

AUDIO INPUT Connections
When Using in NORMAL MODE

To play signals input to the AUDIO INPUT terminal, use “INPUT SELECT” on the “Main Setup” menu to set each channel to AUX.
Example
Connect the left and right channels from the audio source to audio inputs of arbitrary numbers.

When Using in BRIDGED MODE
Input BRIDGED output signals to an even-numbered input terminal.
Example
Connect the left and right channels from audio source to audio inputs of arbitrary numbers.

Connections to Other Devices

ETHERNET Connections

Required System

Broadband Internet Connection
A broadband line connection to the Internet is required in order to use the POA-3012CI’s firmware update.

Modem
This is a device that is connected to the broadband line to communicate with the Internet. Some are integrated with the router.

Router

• When using the POA-3012CI, we recommend you use a router equipped with the following functions:
  • Built-in DHCP (Dynamic Host Configuration Protocol) server This function automatically assigns IP addresses on the LAN.
  • Built-in 100 BASE-TX switch

When connecting multiple devices, we recommend a switching hub with a speed of 100 Mbps or greater.

Ethernet Cable (CAT-5 or greater recommended)

• The POA-3012CI does not come with an Ethernet cable.
• Some flat type Ethernet cables are easily affected by noise. We recommend using a normal type cable.
• If the sound is broken in an environment in which there is much power supply noise from electric products or in a noisy network environment, use a shielded type Ethernet cable (For North America model).
• For the Ethernet cable, used a shielded twisted pair (STP) cable. Do not use an unshielded twisted pair (UTP) cable, as it may exceed noise standard limits (For Europe model).

Computer
A computer with the following specifications is required to use a server:

• OS
  Windows XP Service Pack2, Windows Vista

• Internet browser
  Microsoft Internet Explorer 5.01 or later

• LAN port
  For connections to the Internet, contact an ISP (Internet Service Provider) or a computer shop.

NOTE

• A contract with an ISP is required to connect to the Internet. No additional contract is needed if you already have a broadband connection to the Internet.
• The types of routers that can be used depend on the ISP. Contact an ISP or a computer shop for details.

Others

• If you have an Internet provider contract for a line on which network settings are made manually, make the settings at “Network Setup” ( page 15).
• With the POA-3012CI, it is possible to use the DHCP and Auto IP functions to make the network settings automatically.
• When using a broadband router (DHCP function), the POA-3012CI sets the IP address, etc., automatically. When using the POA-3012CI connected to a network with no DHCP function, make the settings for the IP address, etc., at “Network Setup” ( page 15).
• The POA-3012CI is not compatible with PPPoE. A PPPoE-compatible router is required if you have a contract for a line of the type with which the PPPoE is set.
