THX Ultra2
Before any home theater component can be THX Ultra2 certified, it must incorporate all the features above and also pass a rigorous series of quality and performance tests. Only then can a product feature the THX Ultra2 logo, which is your guarantee that the Home Theater products you purchase will give you superb performance for many years to come. THX Ultra2 requirements cover every aspect of the product including power amplifier performance, pre-amplifier performance and operation, as well as hundreds of other parameters in both the digital and analog domain.
In addition to improvements to the power amplifier with respect to previous THX Ultra standards, three surround modes have been added: the THX Ultra2 Cinema mode, THX Music Mode and THX Games Mode.
Check that the following parts are supplied with the product.

About channel level meter
You can select the output level (dB indicator) of each power amp channel to check the meter.
If a sine wave is input, the output power for the meter indicator is as shown in the following table.
Output indicator | 4 Ω/ohms load | 6 Ω/ohms load | 8 Ω/ohms load |
0 (dB) | 300 (W) | 200 (W) | 150 (W) |
–10 (dB) | 30 (W) | 20 (W) | 15 (W) |
–20 (dB) | 3 (W) | 2 (W) | 1.5 (W) |
–30 (dB) | 300 (mW) | 200 (mW) | 150 (mW) |
–40 (dB) | 30 (mW) | 20 (mW) | 15 (mW) |
–50 (dB) | 3 (mW) | 2 (mW) | 1.5 (mW) |
Output indicator | 4 Ω/ohms load | 6 Ω/ohms load | 8 Ω/ohms load |
0 (dB) | 1200 (W) b | 800 (W) b | 600 (W) b |
–10 (dB) | 120 (W) | 80 (W) | 60 (W) |
–20 (dB) | 12 (W) | 8 (W) | 6 (W) |
–30 (dB) | 1200 (mW) | 800 (mW) | 600 (mW) |
–40 (dB) | 120 (mW) | 80 (mW) | 60 (mW) |
–50 (dB) | 12 (mW) | 8 (mW) | 6 (mW) |
NOTE
When outputting a program source that has data such as SACD, which is higher than the audible band, the indicator moves differently than the volume you hear.
NOTE
The ~ and must be set before turning the power on. Settings which are changed after powering on will not be registered. In such cases, the power should be switched off and on again.
Connections for all compatible audio signal formats are described in these operating instructions.
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-A1HD. For details, refer to the instructions for the respective connection items below.
NOTE
Select the cables according to the equipment being connected.
Audio cables | Signal direction |
Analog connections (XLR) Balanced cable | Audio signal |
Analog connections (RCA) Pin-plug cable | |
Speaker connections Speaker cables |
Carefully check the left (L) and right (R) channels and + (red) and – (black) polarities on the speakers being connected to the POA-A1HD, and be sure to interconnect the channels and polarities correctly.
NOTE
Protection circuit
If speakers with an impedance lower than specified are used for an extended period of time with the volume turned up high, the temperature may rise, activating the protection circuit.
When the protection circuit is activated, the speaker output is shut off and the power indicator flashes red. If this happens, unplug the power cord, then check the speaker cable and input cable connections. If the set is extremely hot, wait for it to 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.
NOTE
The MODE, CONTROL, Operation mode select switch and Input select switch must be set before turning the power on. Settings which are changed after powering on will not be registered. In such cases, the power should be switched off and on again.
[Rear panel]
Change the input mode for each channel (L1 ~ L5, R1 ~ R5).
Set the Input select switch.
NOTE
Change the operation mode for each channel (L1 ~ L5, R1 ~ R5) or pair channel (L1 / L2, L3 / L4, L5 / R5, R1 / R2, R3 / R4).
Bi-AMP / NORMAL / BRIDGE mode selection
Set how to use the power amp with each channel.
Set the Operation mode select switch.
NOTE
Select the option suited for the equipment operating the unit.
Select CONTROL.
When CONTROL is set to " AVP", the PRE AMP CONTROL LINK indicator lights in blue.
OPTION / 1 / 2 mode selection
Use control link to connect POA-A1HD and AVP-A1HD and switch POA-A1HD according to the number of units to be connected.
Select MODE.
This example shows the connection of an AV sound preamplifier AVP-A1HD (sold separately) to the unit.
To operate POA-A1HD from AVP-A1HD, connect the control link cable, set CONTROL switch to "AVP" and then set MODE switch to "1".
NOTE
Always set the Input select switch for channels not in use to "OFF".
Example: 7-channels (NORMAL setting)
Example: 7-channels (NORMAL setting)
The AVP-A1HD can be operated when connected to 2 POA-A1HD units.
Settings
Please refer to the AVP-A1HD owner's manual for setup and operation instructions.
Set the rear panel "Operation mode select switch" and "Input select switch" according to the connection method.
NOTE
The Operation mode select switch and Input select switch must be set before turning the power on. Settings which are changed after powering on will not be registered. In such cases, the power should be switched off and on again.
Connection for signal input to each channel to be output from the channel's speaker terminal.
Example: Normal connection to the channel
NOTE
When using only speaker A or B | 4 ~ 16 Ω/ohms |
When using speakers A and B at the same time | 8 ~ 16 Ω/ohms |
Bi-wiring connection
When using speakers that have input terminals for both woofer units and tweeter units, this connection allows for the same signal to be output from each unit. With this connection the interference between signals for the woofer unit and tweeter unit is low so that you can enjoy high quality sound in playback.
NOTE
When using Bi-Wiring connection use 4 ~ 16 Ω/ohms speakers for the impedance.
When using speakers that have input terminals for both woofer units and tweeter units, this connection outputs one input signal from the two amps on the main unit to each of these units. With this connection the interference between signals for the woofer unit and tweeter unit is eliminated so that you can enjoy high quality sound in playback.
NOTE
The input terminal (channel in case of and ) that is not used for this setting becomes invalid regardless of the status of Input select switch.
Example: Bi-Amp connection using and channels
NOTE
RISK OF ELECTRIC SHOCK
DO NOT OPEN
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. | |
