State-of-the-art Denon Solutions for
Maximizing Content Quality
4 Ohms Guaranteed Mono Block Construction Amplifiers
The POA-A1HDCI is a 10-channel high-output power amplifier with 300 watts (4
ohm) of uniform-quality current for each channel. To ensure maximum performance
as an audio amplifier, this model has been designed with a discrete monaural configu-
ration where each channel is endowed with its own parts and radiator. Interference
between channels has been eliminated to produce highly pure sound with a realistic
sound space.
150 W x 10 channels (8 ohms), 300 W (4 ohms)
300 W Bridgeable derive (8 ohms), 500 W (4 ohms)
10-channel power amp capable of driving low-impedance speakers
THX Ultra2 certified Power Amplifier
Fully separated construction for each 10 channels for all same audio quality
Mono block concept to amplify with best performance
Separate winding in power circuit for each channel
New amplifier circuit that shortens audio signal paths for the best audio
Direct Mechanical Ground to minimize mechanical vibration from
transformer and radiators
8 individual transformers to supply power to each discrete circuit
4 main power transformers to drive 10 ch power amplifiers with sepa-
rated coil winding for pure audio playback
The main power unit for the power amp is configured of four large transform-
ers dedicated to the power amp section, large-capacity block capacitors, and
large-capacity rectifying diodes, to provide a stable supply of current from the
main power supply block. This highly reliable current allows listeners to freely
enjoy high-quality sound even during dynamic playback of surround sound or
multi-channel sources. The power unit also has two independent pairs of large
transformers, one for each stereo channel, and each channel is independently
configured from a secondary coil on each transformer to suppress interference
between circuits and ensure superior sound quality.
