BENZO / JohnH M2
The Ballarino Amplification version of the legendary JohnH M2 attenuator. The BENZO / JohnH M2 is a fully passive, adjustable, reactive power attenuator for tube amps with up to 4 octal output tubes (e.g. 4xEL34, 4x6L6, 4xKT66,..) with a rated output power of 100W.
Originally developed by JohnH and documented in an extensive thread on www.marshallforum.com. Hundreds of units built and tested by folks at home, this is now a production version of this highly advanced and effective amp attenuator.
Both 8 and 16 Ohm versions have output jacks for connecting speakers with either 8 or 16 Ohms and switchable stages with an attenuation of -7dB down to -31.5dB, which reduce the volume of a cranked 100W amp down to living room levels. An amp-powered fan guarantees cooling the whole unit when attenuating powerful amps. No power supply needed.
The Benzo can be used as a load box without connecting any speaker when the highest attenuation setting is used (all 3 switches down).

Weight: 1.5kg (3.3lbs)
Input impedance: 8 or 16 Ohm, depending on model
Reactive load: yes, simulates speaker impedance curve
Output jacks: 1x16 or 1x8 or 2x16 Ohm
Base attenuation: -7dB
Switchable attenuation stages: -14dB, -7dB, -3.5dB (combined with base attenuation for a maximum of -31.5dB)
Fan: 60x25mm
High quality Neutrik jacks
Heavy-duty aluminum enclosure, acting as a heatsink
Rated power: 120W continuous, 200W for t<15min
Line-Out-Mod (optional):
Optionally we can add an unbalanced, adjustable line-out to your Benzo unit. Can be used for direct recording, connecting an IR loader + headphones for silent playing, you name it.
Consists of an extra 1/4" jack and a potentiometer for adjusting the line-out level.
