INSTA ATION
1. osition the amplifier so that children or pets can not inadvertently touch the tubes.
2. Locate the amplifier where there is adequate ventilation – at least 5 inches of space above it.
3. To minimize the chance of hum, place it away from other units’ transformers or motors.
4. With the amplifier’s power switch in the ‘Off’ position, insert the tubes as marked by the numbers on the
tubes, and on the top, back or bottom of the amplifier. Take care to align the ‘key’ at the base of the each
tube with the socket ‘key’. With the miniature tubes, a gap exists in the pins which indicates the correct
alignment. Be sure to press the tubes gently, but firmly all the way down into the tube sockets. For the
larger tubes, grasp the tube at the base, not the glass portion.
CAUTION: It is possible some manufacturer's KT77 / E 34 and 5AR4 types can still be inserted
even if the key is not aligned properly. Make sure the key is aligned by visual inspection. Also, do
not 'rock' these tubes back and forth to insert them. Doing so can break off the key post entirely,
requiring service of the amplifier.
5. Insert the appropriate RCA plugs into the input jacks. Make sure the plugs are fully inserted into the
jacks with the outer skirt of the plug tight around the socket. The input impedance is a high 270K ohms,
making it very easy to drive.
6. When connecting the speakers, be sure to observe the correct OLARITY of the connection, with the
RED connected to the RED or plus marking on the speaker and the BLACK connected to the BLACK or
minus marking on the speaker. This amplifier does not reverse polarity.
BIAMP IFICATION OR TRIAMP IFICATION USE
The Royale SE ower Amplifier was ‘voiced’ to sound best with the Wright Audio Oasis reamplifier for
even greater performance in a bi-, or preferably tri-amplification system using an external crossover.
Tonal balance can now be provided via the crossover’s volume level controls for the tweeter, midrange and
bass speaker drivers provided the speaker system has provision for directly connecting its drivers to the
respective power amplifier’s output bypassing the speaker system’s internal passive crossover.
This arrangement provides maximum power transfer from the amplifier directly to the drivers for maximum
efficiency, best sound and most effective crossover slopes. This arrangement also makes practical the use
of 2 or more high quality, but lower-output single-ended triode type amplifiers as the ideal solution for the
ultimate stereo system. It is recommended that some sort of passive protection be provided to a tweeter
when so connected in a tri-amplified system.
GENERA OPERATING NOTES AND MAINTENANCE
When new, your unit will require 4 or 5 days of operation for about 2 hours per day before it ‘breaks in’ and
begins to sound its best. It will continue to improve during the first few weeks of operation.
Operate your Wright Audio amplifier only when you are actively listening to it. Unlike solid-state equipment,
Wright Audio amplifiers reach their optimum listening quality only in about15 minutes and it is simply a
waste of power and tube life to leave the amplifier on continuously.
