BI-AMPING
• IMPORTANT: REMOVE the terminal links and store them safely.
• Bi-amping allows two independent audio power amplifier of equal or similar quality to be used for LF and
HF signals. The benefits of bi-amping include reduced intermodulation distortion because the low and
high frequency signals are amplified independently, and more power reserve and dynamic range
because each amplifier has less ‘work’ to do than a corresponding single amplifier.

4 POWER RATING
The technical specification shows a nominal power rating for your loudspeaker and the figure can be taken
as a rough guide to the power rating, Watts per channel into 8ohm load, for a complementary amplifier.
However, provided you NEVER play at levels where the sound is strained or distorted, the power rating is not
critical provided you have a minimum of about 15 Watts per channel and a maximum of 250 Watts per
channel available. If the sound is strained always turn the playing level down immediately. Ask your dealer
for advice if you are unsure or if you are choosing a new amplifier.
5 RUNNING-IN
The performance of any loudspeaker will improve subtly during initial use especially if the loudspeaker has
been stored in a cold environment or not used for an extended period. The drive unit suspension and any
damping materials will ‘break in’ and settle during the first 24-48 hours of playing. This running-in period may
vary. Allow up to a week for the loudspeaker temperature to stabilise and a further 48 hours of continual
operation for the loudspeaker to deliver its full potential.
6 MAINTENANCE
Spendor’s real wood veneers and solid timber elements should be treated like high quality furniture. Routine
dusting with a soft cloth is recommended. Do not apply any aerosol spray directly as this could damage the
drive units or grille fabric. Dust on the grille cloth can be removed with a sticky roller or a piece of sticky tape
or by gentle vacuuming with a soft brush adaptor. Do not expose the cabinets to damp, widely fluctuating
temperatures or direct sunlight, the appearance and performance may suffer. The SR5 cabinets are finished
in natural wood, over time the wood will age and mature, often darkening the surface colour while
highlighting the natural grain and patina.
