Octave V 70 SE [23/33] Using the super black box

10. USING THE (SUPER) BLACK BOX

Description

OCTAVE, with the Black Box technology, offers an instrument for optimizing the OCTAVE amplifier

in respect to the speaker. This flexibility is a unique feature of the OCTAVE brand.

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

12.1. The Black Box option

Black-Box

Indicator LED Hi

h-current plu

The LED illuminates continuously when the power amplifier is on.

The LED goes out when the protection circuitry trips. This is normal, as the protection circuitry cuts

the power to the amplifier.

Connecting to the amplifier



Important! Before connecting the Black Box, switch off the unit using the

power switch and wait for 1 minute.

When inserting the connector, guide the anti-rotation lug carefully into the

mating recess in the socket.



When you switch the amplifier on, the LED on the front panel of the Black

Box will illuminate.

Note: The LED on the Black Box goes off when the amplifier's electronic

protection circuitry is activated, as the protection circuitry shuts off the

power to the amplifier.



Should you wish to disconnect the Black Box, switch off the amplifier firs

and wait until the LED on the Black Box has gone out.
