Blue Circle’s True Balanced Output Technology

Most current amplifier designs, even if they have balanced inputs, do not necessarily have true balanced outputs. This means that the positive binding posts have signal but the negative binding posts are actually tied to ground. With this approach the positive binding posts are driving the speaker coils but the negative binding posts are entirely passive.

All 200 Series Blue Circle amplifiers* employ true balanced output technology. This means both the positive and negative binding posts supply active signal to the speaker voice coils. The advantage This results in the amplifier applying more control over the speaker cone motion than conventional designs.

We began using balanced outputs in 1999. Since that time the technology has undergone many refinements to reach its current level of performance.

The BC206 is the first model to take advantage of the latest design refinements to our balanced output technology. Since the negative binding posts are in fact not grounds as in most other amplifier designs we have included independent chassis /earth grounds on the rear panel of the BC206 to accommodate installations that may require the application of a true ground.

To meet the requirements of today's home theatre systems a 12 volt trigger option is available on all Blue Circle Power Amplifiers.  This facilitates remote control by the system processor of the on/off function of the amplifiers.

All Blue Circle products are available in 100V, 110V, 120V, 200V, 220V, 230V, 240V models
