I21 AMPLIFIER USER GUIDE

Welcome to the I21 Integrated Amplifi er

The I21 is an integrated preamplifi er and power amplifi er with extraordinary performance for its price.

High-performance power amplifi er

The I21 incorporates a power amplifi er providing 75 Watts per channel of superb quality sound.

Flexible inputs

The I21 preamplifi er stage provides four inputs, labelled

CD, TUNER, LINE 1, and LINE 2, to cater for a fl exible range of sources.

Fixed and variable outputs

The currently selected source is provided on two pairs of line-level outputs, for connecting the I21 to other equipment. The TAPE OUT sockets are independent of the position of the volume control, and allow you to connect the

I21 AMPLIFIER USER GUIDE

INTRODUCTION

Welcome to the Primare I21 Integrated Amplifi er! 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.

I21 to a tape recorder. The PRE OUT sockets are controlled by the volume control, and can be used to connect the I20 to another output stage.

Superb technical design

The I21 incorporates a classic circuit design based on J-FET input devices and bipolar output devices, typical of far more expensive equipment, giving high performance and excellent reliability.

Intuitive user interface

In keeping with the philosophy of the Primare range of systems, the I21 can be controlled through a very simple and intuitive set of front panel controls.

Alternatively all the functions of the I21 can be controlled by the C22 Remote Control supplied with the I21, along with the other Primare components in your system.

INTRODUCTION

Using the I21 with other Primare products

Although the I21 is fl exible 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.

A particular benefi t of using the I21 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.

Power connection

Warning: Before connecting power check that the required supply voltage, indicated on the back panel, cor re sponds to your local

AC supply. If a different voltage is stated on the type plate do not connect the I21 to the mains power, and seek advice from your dealer.

Connect the mains power using the enclosed mains cable.

NOTE: Always disconnect the I21 and all other units in the system from the mains power before connecting or disconnecting any of the cables. Never short circuit speaker terminals. This might seriously damage the unit.

Safety instructions

To prevent fi re or shock hazard, do not expose this appliance to dripping or splashing. No objects fi lled with liquids, such as vases, should be placed on the I21.

If you want to build in the I21 you need to be sure to allow space of at least 20 cm behind, 10 cm on both sides and 30 cm above the top panel of the unit. This is to prevent fi re or damage caused by overheating. Also make sure that the main switch is accessable.

HOW TO GET STARTED

This chapter provides a quick overview of how to connect the I21 integrated amplifi er to other components in your system.

Switching on and off

To switch on

• Use the main switch under the left-hand edge of the housing (1).

During normal operation you can leave the I21 switched on and in standby mode.

To switch on from standby or to standby

• Pressing on the front panel or on the remote control, will change the standby mode.

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.

Preamplifi er outputs

The PRE OUT sockets provide a line-level output from the I21 preamplifi er stage which can be connected to another preamplifi er. The level of this output is controlled by the VOLUME control on the I21.

The TAPE OUT sockets provide a fi xed level copy of the currently selected source, suitable for connecting to a tape recorder.

HOW TO GET STARTED

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 preamplifi er 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

I21, such as LINE1.

OPERATING THE I21 INTEGRATED AMPLIFIER

This chapter explains how to operate the I21 Integrated

Amplifi er, using either the front panel controls or the remote control.

Selecting a source

The I21 Integrated Amplifi er provides a choice of four line inputs, labelled: CD, TUNER, LINE 1, and LINE 2.

To select a source

• Press the button on the front panel or the remote control corresponding to the source you want to select.

The currently selected source is indicated on the front panel display:

Changing the volume

The I21 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 – or + buttons on the remote control.

The current volume setting is shown on the front panel.

• Alternatively, press the or buttons on the remote control to step between sources.

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 BAL/ST button on the 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.
