Welcome to the I21 Integrated Amplifier The I21 is an integrated preamplifier and power amplifier with extraordinary performance for its price. High-performance power amplifier 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 power amplifier providing 75 Watts per channel of superb quality sound. Flexible inputs The I21 preamplifier stage provides four inputs, labelled CD, TUNER, LINE 1, and LINE 2, to cater for a flexible range of sources. Fixed and variable outputs 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 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 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. 1 INTRODUCTION Using the I21 with other Primare products Although the I21 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. A particular benefit 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, corresponds 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. NOTE: Always disconnect the I21 and all other units in the system from the mains power before connecting or disconnecting any of the cables. This might seriously damage the unit. Switching on and off To switch on · Use the main switch under the left-hand edge of the housing (1). Safety instructions To prevent fire or shock hazard, do not expose this appliance to dripping or splashing. No objects filled with liquids, such as vases, should be placed on the I21. [. . . ] The currently selected source is indicated on the front panel display: · 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. I21 AMPLIFIER USER GUIDE 7 OPERATING THE I21 INTEGRATED AMPLIFIER 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 To dim the front panel display · Press the DIM button on the remote control. The display will dim to show just the currently selected source. · 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. To restore the normal display · Press the DIM button again. · Press the ­ or + buttons on the remote control to adjust the balance. [. . . ]
