Introduction

Welcome to the Primare A30.5 Amplifier! This chapter introduces you to its key

features, and explains how you can take advantage of its impressive power

handling and superb sound in your system.

WELCOME TO THE A30.5 AMPLIFIER

The A30.5 is a modular power amplifier designed as the ideal output stage in

a home theatre system.

Modular design

The A30.5 is designed as five independent blocks, each with a separate

transformer and power supply, for the ultimate in stability and channel

separation.

Generous power handling

Each section of the A30.5 delivers 120 Watts into 8Ω, giving sufficient power

reserves for home cinema or the reproduction of recorded music. An over-

dimensioned heat sink gives excellent thermal dissipation.

Superb quality

The A30.5 delivers its power at an outstanding quality level, making it as

suitable for reproducing high quality recorded music as for home cinema.

Remote power on/off

For convenience the A30.5 can be powered on and off via a remote link

cable, avoiding the need to switch it on or off separately from the preamplifier

in the system.

USING THE A30.5 WITH OTHER PRIMARE

PRODUCTS

Although the A30.5 is flexible enough to act as the output stage in virtually

any system, it is ideal for use with other products in the Primare range, such as

the Primare P30 Processor. The A30.5 can be used as a building block in

conjunction with the Primare A30.2 and A30.3 to create modular systems with

any desired number of matched output stages, and one or more A30 Series

amplifiers can be powered on or off remotely from a P30 using the remote link

connections.

POWER CONNECTION

Warning: Before connecting power check that the required supply voltage,

indicated on the back panel, corresponds to your local AC supply. If a

different voltage is stated on the type plate do not connect the amplifier to the

mains power, and seek advice from your dealer.

Connect the mains power using the enclosed mains cable.

Note: Always disconnect the amplifier from the mains power before

connecting or disconnecting any of the cables.

Switching on

The mains switch is on the base plate at the front, to the left under the front

plate. After the switch is activated, the indicator on the front panel lights up

green.

OUTPUTS

Loudspeaker outputs

Connect the loudspeakers for each channel to the corresponding terminals.

The terminals can accept speaker cables terminated with 4mm banana plugs,

spade terminals, or bare wires. To connect bare wires unscrew the terminal,

pass the bare wire through the hole in the terminal bolt, and clamp the wire in

place by screwing the terminal back down.

INPUTS

Connect the A30.5 to each channel of the preamplifier or processor using the

corresponding phono inputs, using high quality phono leads.

REMOTE LINK

To power the A30.5 on and off remotely from a Primare P30 Processor

connect the REMOTE output from the P30 Processor to one of the REMOTE

LINK sockets on the A30.5, using a twin core cable terminated in 3.5mm jack

plugs. The second REMOTE LINK socket can be used to daisy-chain the

remote output to further A30 series amplifiers.

Note: Ensure that the P30 is switched off before connecting it to the A30.5

with a remote link cable.

To use the remote link, switch the REMOTE SW switch to the ON position.
