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.
