Introduction
Welcome to the Primare A30.1 Integrated Amplifier! This chapter introduces
you to its key features, and explains how you can take advantage of its superb
sound as the key component in your hi-fi system.
WELCOME TO THE A30.1 INTEGRATED AMPLIFIER
The A30.1 is an integrated preamplifier and power amplifier with
extraordinary performance for its price.
High-performance power amplifier
The A30.1 incorporates a power amplifier providing 100 Watts per channel
of superb quality sound.
Flexible inputs
The A30.1 provides six inputs for sound sources such as a CD player, radio
tuner, and tape recorders. An optional RIAA amplifier is available if your
system includes an analogue record player.
Fully balanced
Two of the inputs are balanced, giving an entirely balanced signal chain when
used in conjunction with a source that provides balanced outputs, such as the
Primare D30.2 CD Player.
Fixed and variable outputs
The currently selected source is provided on two pairs of line-level outputs, for
connecting the A30.1 to other equipment. The TAPE OUT sockets are
independent of the position of the volume control, and allow you to connect
the A30.1 to a tape recorder. The PRE OUT sockets are controlled by the
volume control, and can be used to connect the A30.1 to another output
stage, or a digital surround processor such as the Primare P30.
Intuitive user interface
In keeping with the philosophy of the Primare range of systems, the A30.1 can
be controlled through a very simple and intuitive set of front panel controls.
Alternatively all the functions of the A30.1 can be controlled by the C30
Remote Control, along with the other Primare components in your system.
USING THE A30.1 WITH OTHER PRIMARE
PRODUCTS
Although the A30.1 is flexible enough to work with virtually any other
equipment you have in your system, it is ideal for use with the other products in
the Primare range, such as the Primare D30.2 CD Player. A particular benefit
of using the A30.1 with other Primare sources is that you can control your
entire system with a single remote control, to give you a fully integrated system
with the simplest possible user interface.

Using the A30.1 Integrated Amplifier
This chapter explains how to operate the A30.1 Integrated Amplifier, using
either the front panel controls or the C30 Remote Control.
]A The source switch selects one of the six sources.
]B The MONITOR button selects the tape monitor.
]C The VOLUME control changes the volume.
]D The 0°/180° button changes the phase.
]E The STANDBY control switches the A30.1 to standby, or switches it on.
FRONT PANEL CONTROLS
All the functions of the A30.1 Integrated Amplifier can be accessed using the
five front panel controls, and information about its operation is displayed on
the discreet front panel indicators:

SWITCHING ON AND OFF
To switch on
•Use the switch under the left-hand edge of the front panel.
During normal operation you can leave the A30.1 switched on and in
standby.
To switch to standby
•Turn the STANDBY control switch on the front panel to STANDBY, or
press the STBY button on the remote control.
To switch on from standby
•Turn the STANDBY control switch on the front panel to OPERATE.
Selecting any function with the remote control will also switch on the A30.1
from standby.
SELECTING A SOURCE
The A30.1 Integrated Amplifier provides a choice of six inputs, labelled: B1,
B2, CD, TV, AU, and TA.
To select a source
•Turn the source selector until the source is indicated on the front panel
display.
•Alternatively, press the SEL Aor SEL Vbuttons on the C30 Remote
Control to step between sources.
CHANGING THE VOLUME
The A30.1 allows you to vary the volume from 0 (silence) to 79 (maximum
volume).
To change the volume
•Rotate the volume control on the front panel, or press the VOL Aor
VOL Vbuttons on the C30 Remote Control.
The current volume setting is shown on the front panel.
CHANGING THE BALANCE
You can change the balance of the sound between the left and right channels
to shift the position of the stereo image.
To change the balance
•Press the MENU button on the C30 Remote Control.
The front panel display shows the current balance setting, where -6
corresponds to the leftmost position, 0 corresponds to centre, and 6
corresponds to the rightmost position.
•Press the VOL Aand VOL Vbuttons on the remote control to adjust the
balance.
•Press the MENU button again to revert to the normal volume display.
Alternatively the normal display will revert automatically after four seconds.

CHANGING THE PHASE
The phase button on the front panel can be used to change the phase from 0°
(non-inverted) to 180°(inverted), to restore absolute phase on source materials
that have been recorded with the incorrect phase.
•Push the button in to select 180°or release it to select 0°
The correct phase setting will give a more open and spacious reproduction of
the music, which is especially audible as the sound decays.
MAKING RECORDINGS
The A30.1 Integrated Amplifier allows you to make a recording of any source
to the tape output. If your tape recorder provides a monitor output you can
compare the recording to the original source (A-B monitoring).
To make a recording
•Connect the TAPE OUT sockets to your recorder inputs.
•Select the source you want to record.
To monitor the recording
•Connect the tape recorder monitor output to the TAPE INPUT sockets.
•Press the MONITOR button on the front panel to switch between the
monitor output and the original source.
When the monitor output is selected an indicator is shown above the
MONITOR button on the front panel display.
The MONITOR button has no effect when the TA source is selected, and the
monitor indicator will flash to indicate the error.

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.
OUTPUTS
Loudspeaker outputs
Connect the left and right loudspeakers 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.
Preamplifier outputs
The preamplifier output sockets provide a line-level output from the A30.1
preamplifier stage which can be connected to another power amplifier, such
as the Primare A30.2. The level of this output is controlled by the volume
control on the A30.1.
The TAPE OUT sockets provide a fixed level copy of the currently selected
source, suitable for connecting to a tape recorder.
The TAPE1 OUT sockets provide a fixed level copy of the currently selected
source, or a copy of the TAPE1 input, depending on the position of the
MONITOR switch.
INPUTS
Source inputs
Connect each source to the appropriate source input, connecting the right
channel to the red socket and the left channel to the white socket.
To connect an analogue turntable with a moving magnet or moving coil
cartridge you will need an additional phono preamplifier such as the Primare
R20. The output of the turntable is connected to the R20, and the output of the
R20 should be connected to a spare input on the A30.1, such as AUX.
A ground terminal is provided below the input sockets to allow you to provide
a direct ground connection for sources in order to remove hum loops.
