Black Box

Description

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.

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 up-

grades 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 criti-

cal, 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 interfer-

ences due to the noise filtering characteristics of the capacitors.

Operation

Black-Box

Indicator LED Hi

h-current plu

g

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.

Specification

Dimensions 170 x 97 x 257 mm (W x H x D)

Weight 2.5 kg

Connection cable Length: 70 cm.

Longer lengths available upon request.

Connecting to the amplifier

Important! Before connecting the Black Box, switch the unit

off 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 out 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 the

amplifier off first and wait until the LED on the Black Box

has gone out.

Safety instructions and partnering amplifiers

Do not open the case

Because of the dangerously high voltages inside this unit, only

qualified personnel should open the case.

Location

OCTAVE equipment is designed strictly for use in a dry domestic

environment. Do not use it in the open air or in damp

environments! Never place plants or liquid-filled containers on

the equipment. Care should be taken to avoid objects falling into

or liquids being spilled into the case. Should this happen,

remove the mains plug immediately and have your amplifier

checked by a qualified service technician.

This instructions you can also find in the

owner's manual of your amplifier.
