Design and Construction
The Rega Solis is built around a Class A/AB output topology. The amplifier chassis incorporates substantial heatsinking and a rigid enclosure structure designed to support thermal stability and mechanical integrity during operation.
The internal layout follows a direct signal path approach, using discrete amplification stages and a linear power supply architecture.
Power Supply Architecture
The Solis incorporates a toroidal transformer and regulated power supply sections to provide current delivery to the output stage. The power supply is designed to maintain stable voltage conditions across varying load demands.
This configuration supports compatibility with a range of loudspeaker impedance profiles commonly found in domestic hi-fi systems.
Connectivity
The rear panel includes balanced XLR and unbalanced RCA inputs, allowing connection to compatible pre-amplifiers and control components. Loudspeaker outputs are provided via binding posts designed to accommodate standard speaker cable terminations.
The Solis operates as a dedicated power amplifier and does not include integrated source switching or volume control.
System Integration
The amplifier is intended for use within separate-component systems where a pre-amplifier manages input selection and signal control. Its connectivity options allow pairing with analogue pre-amplifiers, DAC pre-amplifiers or integrated streaming control stages with line-level output.
