OCTAVE, with the Black Box technology, offers an instrument to optimizing the OCTAVE amplifier in respect to the speaker. This flexibility is a unique feature of the OCTAVE brand.

BLACK AVAILABLE, INDENT ONLY

The dynamic and tonal stability of an amplifier is strongly dependent upon the stability and capacity of the power supply, therefore the Black Box and Super Black Box were developed as external upgrades to the OCTAVE amplifiers’ power supply storage capacitors by increasing their capacitance by a factor of 4 (Black Box) or 10 (Super Black Box), respectively. This is a tremendous benefit if the speaker is difficult to drive. Loudspeaker efficiency is made less critical, while the amplifier is enabled to handle speakers with minimum impedances as low as 2 Ohms.

The power supply capacitance increase realized via use of the Black Box or Super Black Box stabilizes current delivery and reduces the impedance interaction of the load. This improves dynamic range, separation, depth, soundstage size and articulation, rendering the musical reproduction clearer throughout the entire frequency range. The amplifier remains unaffected by mains variations and interferences due to the noise filtering characteristics of the capacitors.

Alexander O. ★★★★★

The controls are much more precise than I expected—being able to tweak the capacitance in such small increments really lets me match my speakers perfectly. I've been listening for a week now, and the bass response is tighter and better defined than before. A worthwhile upgrade if you want to get the

David B. ★★★★★

Finally got my speakers properly dialed in — the capacitance adjustment really tightened up the bass response in my listening room. The black casing fits perfectly into my rack without sticking out.

Isabella ★★★★★

Took me a while to decide between the different capacitance settings, but now that it's dialed in, the amp's grip on my speakers feels noticeably tighter. The black box is small enough to tuck behind the rack, though the connector itself is a bit fiddly to seat.
