Octave V 40 SE Integrated Amplifier

The V 40 SE is a line level integrated amplifier with 2 x 40 W peak output power. He is a further development and direct descendant of the successful V 40 and V 50 amplifier models. His powerful, clear bass fundamentals and his captivating resolution in the high frequencies win much respect.

The V 40 SE output stage consists of two power pentodes (Type 6550 JJ) for each channel. Due to the BIAS Control and Monitoring System, the use of other pin-compatible output tubes is possible to match the amplifier to personal taste, or to benefit from new or improved tubes.

Like all OCTAVE amps the V 40 SE is based on the enhanced pentode configuration. This configuration ensures the absolute stability of the amplifier against the unstable impedance of the loudspeaker. Impedance mismatch is without consequence and the V 40 SE is stable down to a 2 ohms load.. An important contributor to this stability is the single impedance output transformer.

The V 40 SE is the perfect amp for speakers with an average efficiency rating. But not only is the low impedance capability an advantage, with his exceptional Signal-to-Noise ratio of –110dB / Full Power he is also an ideal partner for high efficiency loudspeakers.

Of course, the V 40 SE features the Power Management with the Soft-Start-Electronics, the Protection System, Eco Mode, BIAS Setting and Display, a Monitor/Record Output, the HT Bypass, the Pre-Out and a (Super) Black Box Connection.

Super Black Box

Like the Black Box, the Super Black Box is also an external power supply amplifier for the integrated amplifiers V 40 (SE), V 50, V 70 (SE), V 70 Class A, V 80 (SE), V 110 (SE) and V 16 Single Ended and the RE 280 MK2, RE 290, RE 320, MRE 130 and MRE 220 (SE) power amplifiers, but with even greater capacity.
