Περιγραφή
The A30.2 is a two-channel modular power amplifier designed as the ideal output stage in a
home theatre or hi-fi system.
Audiophile circuit design
The A30.2 power amplifier is a dual-mono design, which means that it incorporates two
compact mono power amp channels each with a separate transformer and power supply. This
provides the ideal conditions for optimum stability and channel separation.
The heat sinks are massive to keep the temperature at a moderate level even under the most
difficult working conditions.
The amplifier is capable of delivering 120watts into an 8 ohms load and incorporates full
speaker protection against faulty input signals. One individual DC-servo for each channel
together with protection circuit and temperature monitoring provide state-of- the-art protection.
It can internally be configured as a fully balanced mono power amplifier using either balanced
(XLR) or unbalanced (RCA) inputs. In this mode the A30.2 is capable of delivering 1 x 380W
into an 8ohm load.
Audio connections
Each channel incorporates an unbalanced RCA as well as a balanced XLR input configured
with a backside switch. Massive high quality gold plated speaker terminals suitable for most
audiophile speaker cables are also provided.
The amplifier can be remotely operated with its 12V trigger input, which has a loop-through
output for controlling a second A30.2 or other amplifier.
Shortest signal paths
SMD technology is used whenever possible to keep the shortest possible signal path for the
highest possible performance.
Clean power supply for the best possible performance
Each channel has its own toroidal transformer and a massive electrolytic bank of 40000uF.
The driver stage has separate transformer windings and regulation in four steps. This
configuration produces a high signal to noise ratio and minimises cross-talk from other
channels.
Careful design for operational stability
As with all Primare units, the A30.2 is housed in an alloy heavy gauge steel chassis, which
provides strength, rigidity, and screening, while being effective at damping vibrations from
external sources.
