INTRODUCTION

Welcome to the Primare I21 Integrated Ampli 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- system.

Welcome to the I21 Integrated Ampli er

The I21 is an integrated preampli er and power ampli er

with extraordinary performance for its price.

High-performance power ampli er

The I21 incorporates a power ampli er providing 75 Watts

per channel of superb quality sound.

Flexible inputs

The I21 preampli er stage provides four inputs, labelled

CD, TUNER, LINE 1, and LINE 2, to cater for a  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 equip-

ment. The TAPE OUT sockets are independent of the posi-

tion of the volume control, and allow you to connect the

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 sys-

tems, 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  exible enough to work with virtu-

ally any other equipment

you have in your system, it is

ideal for use with the other products in the Primare range.

A particular bene 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.

I21 AMPLIFIER USER GUIDE

HOW TO GET STARTED

This chapter provides a quick overview of how to connect

the I21 integrated ampli er to other components in your

system.

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 dis-

connecting any of the cables. Never short circuit speaker

terminals. This might seriously damage the unit.

Safety instructions

To prevent  re or shock hazard, do not expose this

appliance to dripping or splashing. No objects  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 pre-

vent  re or damage caused by overheating. Also make sure

that the main switch is accessable.

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.
