Topology
Power-supply topology identifies a linear, switch-mode or combined supply arrangement.
A conventional linear supply uses mains-frequency transformation and rectification with linear regulation; a switch-mode supply controls energy through rapid switching. Hybrid identifies a stated combination of both approaches.
Topology — External Clock
For an external clock, supply topology describes how power is converted for the clock circuitry. Different sections can use different supply arrangements within one product.
A stated combination of linear and switch-mode supplies is hybrid. A transformer shape, low-noise label or unspecified external adapter does not establish the topology; compare the actual supply description.
Topology — Streamer
For a streamer, supply topology describes how power is converted for processor, clock and audio sections. Different sections can use different supply arrangements within one product.
A stated combination of linear and switch-mode supplies is hybrid. A transformer shape, low-noise label or unspecified external adapter does not establish the topology; compare the actual supply description.
Topology — Music Server
For a music server, supply topology describes how power is converted for computer, storage and audio-interface sections. Different sections can use different supply arrangements within one product.
A stated combination of linear and switch-mode supplies is hybrid. A transformer shape, low-noise label or unspecified external adapter does not establish the topology; compare the actual supply description.
Topology — CD Transport
For a CD transport, supply topology describes how power is converted for disc drive, control and digital-output sections. Different sections can use different supply arrangements within one product.
A stated combination of linear and switch-mode supplies is hybrid. A transformer shape, low-noise label or unspecified external adapter does not establish the topology; compare the actual supply description.
Topology — Power Supply
For an external supply, topology describes the power-conversion design inside the supply itself. Its output must also provide the voltage, current and connector required by the component.
Compare topology separately from electrical compatibility. A linear supply is not automatically a suitable replacement for a switching one, and the label alone does not establish output noise under load.
Topology — Headphone Amp
For a headphone amplifier, topology describes the supply feeding its audio circuitry. An external adapter and internal regulation can form different parts of the overall supply arrangement.
Compare the specified supply design and operating conditions. Do not infer topology from amplifier class or from a low-noise claim; supply type alone does not establish noise at the headphone output.
Topology — Preamp
For a preamplifier, supply topology describes power conversion for its gain, buffer and control circuitry. A separate supply enclosure does not identify the conversion method inside.
Compare the stated linear, switching or combined arrangement. Transformer shape and regulator count are separate details, and the supply label alone does not establish line-output noise.
Topology — SACD Transport
For a SACD transport, supply topology describes how power is converted for disc drive, control and digital-output sections. Different sections can use different supply arrangements within one product.
A stated combination of linear and switch-mode supplies is hybrid. A transformer shape, low-noise label or unspecified external adapter does not establish the topology; compare the actual supply description.
Topology — DAC
For a DAC, supply topology describes how power is converted for digital circuitry and analogue output stage. Different sections can use different supply arrangements within one product.
A stated combination of linear and switch-mode supplies is hybrid. A transformer shape, low-noise label or unspecified external adapter does not establish the topology; compare the actual supply description.
