UNiKA UD-064 & UD-064D Switching Power Amplifier
Description:
The UD-064/UD-064D is a high efficient switching power amplifier with a concise and intuitive digital
control interface and elegant style of aluminum facet. Although it comes in capability of high power driving,
the amplifier is crammed into 1U in height and merely sub ten kilogram in weigh due to its adoption of
power efficient and advanced switching technologies in both power supply and power amplification.
4KW Totally in Heavy Load of 2Ω
The UD-064/UD-064D amplifier is by default configured to operate as x4 individual channels (i.e., in x4
single-ended outputs) with 600W of drive capability for each channel with 4Ω speaker. Since the amplifier is
designed to be able to drive heavy loads with equivalent parallelized impedance down to 2Ω, you can even
drastically extend each output capability of the amplifier to the rank of kilowatt if you have speakers
parallelized on the output of the amplifier. Configuring a pair of outputs to work in bridge mode to drive a
4Ω speaker has the same effect as having each single-ended output of the bridged pair to drive a load with
equivalent impedance in half of the intrinsic impedance of the speaker. In either of the circumstances, the
amplifier can deliver power of up to 4KW to its outputs in total.
eXtraTone™ to Compensate Speaker for Bass Loss
The UD-064/UD-064D comes with an unprecedented eXtraTone™ mechanism to compensate speaker for
bass loss by boosting the bass audio on cutoff frequency of the speakers and mirroring the audio below the
the cutoff frequency in a way of harmonic audio over a range of frequency above its cutoff frequency. While
doing so the amplifier does not need to waste energy by sending power below the cutoff frequency to
speakers, the harmonic mirror of audio below the cutoff frequency enforces the audience perceptible feel of
the presence of audio below the cutoff frequency.
Low Pass Filter (LPF) and auto mono mix (LPFMix) dedicated for subwoofer
When a set of bridge output (or a pair of parallelized inputs) is configured in UD-064/UD-064D, a LPF filter
with adjustable cut-off frequency is automatically introduced in the signal path, so that you can direct
connect a subwoofer (or a couple of subwoofers) to its (their) channel output(s). Evenmore, if only one pair
of channels is configured with bridged output or parallized inputs, you can enable LPFMix and
automatically feed the LPF filter with a mono mixed from the other channels. That way you don't need an
extra mixer to generate L+R mix specific for the subwoofer(s).
Concise and Intuitive Digital Control Interface
All the features and functionalities of UD-064/UD-064D are precisely controlled digitally to avoid over time
annoying degradation or deviation introduced by traditional analog treatment. For simplified operation, there
are mere two buttons and one encoder for the whole control and monitoring operation. While the control
interface is concise, the information from it is far rich. Besides the digital volume control and 32-segment
PPM meter with clip hold for each output channel, the digital processor thoroughly provides device
information including temperature of each heatsink and transformer, revolution speed of each fan, AC
voltage, input parallelized and output bridged settings, and etc.. Of course, all the device configuration, such
