INTRODUCTION Thank you for choosing the VIOLA Legacy Amplifier. Great care has gone into the design and manufacture of the Legacy and if properly used, it will give a lifetime of musical enjoyment. We strongly recommend that you read these instructions before you attempt to use the unit, so that you can be sure it is set up to give optimum performance. UNPACKING Please keep all of the packing materials in case you ever need to ship the unit.
LOCATION We recommend that you place the Legacy as close to the loudspeaker as possible, as this reduces the length of speaker cable required. While this may make it necessary to use longer interconnect cables, long interconnects cause less sonic degradation than long speaker cables. The unit may be placed on a stand or shelf, provided it is strong enough. Alternatively, it may be placed directly on the floor.
of the speaker leads on both channels. Your dealer should be able to advise you on the best course of action. If two items in the signal path have the connections to pins 2 and 3 of the XLR connector reversed with respect to the AES standard, this cancels out the problem and you need take no further action. SPEAKER CABLE CONNECTION Caution! • NEVER connect a power amplifier's output terminals to any device other than a loudspeaker. • NEVER short-circuit the amplifier's output terminals.
BI-WIRE CONNECTION Bi-wireable speakers have separate inputs for the high frequency (HF) and low frequency (LF) sections of their cross-overs. These are connected to the power amplifier with separate speaker cables. Bi-wire connection is regarded as superior to using a single cable, as it avoids interactions between the low and high frequencies that may occur when a single speaker cable is used. You will require two sets of speaker cables.

AC POWER CABLE CONNECTION If the wall outlet you plan to use for the Legacy has an on/off switch, check that it is switched off. Insert the supplied AC mains cord into the receptacle on the rear of the Legacy and ensure that it is pushed securely home. Insert the other end of the mains cable securely into the mains outlet.
by connecting from the remote out jack of the first amplifier into the remote in jack of the second. BREAKING IN Although the VIOLA Legacy power amplifier will deliver outstanding performance straight out of the box, you may expect to hear it continue to improve as it reaches its normal operating temperature and its various components "break-in." It has been our experience that the greatest changes occur within the first 25-50 hours.
incorrect type or rating may create a safety hazard or cause damage to the unit and may also result in the warranty being voided. Operating Voltage 100V, 110V or 120V 220V or 240V Fuse Rating T6.25A T3.15A Fuse Size 11/4 inch 5mm x 20mm 2 spare fuses are supplied with the amplifier. Suitable replacements may be obtained from your VIOLA dealer or directly from VIOLA. • After replacing the fuse, switch the amplifier on and check whether it operates normally.
• Check that the input selector and any other relevant switches are set appropriately. • Check that the signal source is playing. • Check that the pre-amplifier and or signal source volume control(s) are set at a level that is loud enough to hear. 3. The front LED is blinking. The Legacy front panel LED will blink when a fault occurs. Count the position of the bright led in the sequence starting with count one after the pause in the sequence. This will be the error code of what shut the amplifier down.
