PRESS RELEASE
Backline Engineering Announces a New Version of ZenTone 7
December 10, 2007
ZenTone7™ is a class-A tube amp combining a vintage design with several advanced features. The main change is a new power supply design that provides a higher voltage for slightly more output power. This new design also provides a low power mode which cuts the output power by more than a factor of 2 in order to proved more output tube overdrive. When combining lower power mode with triode mode, the output power is reduced to around 1 watt. Other changes include an improved direct out speaker emulation design and a preamp design change for smoother high-gain tones.
The new Zentone7 features include:
- 7 watt class-A single-ended amp head (Low Power mode reduces this to 3 watts)
- Authentic 300V tube amp signal path based on classic designs
- Two 12AX7 preamp tubes (substitute 12AT7, 12AU7, 12AY7, 12AZ7 for different tones)
- Select between 3 preamp gain structures (Clean, Crunch, Lead)
- Switch between EL84 or octal output tube with the push of a button
- The octal tube socket can accept 6V6 (included), 6L6, EL34 or KT77 output tubes without re-biasing
- Select output tube Pentode mode or output tube Triode mode for a darker tone with lower output power and more compression
Gain, bass, mid, treble and master volume controls
- Bright switch
- All the above control values can be stored in 64 preset locations
- Unbalanced and XLR direct outputs with level control
- Direct out contains entire tube signal path from the input to the speaker output
- Built-in reactive speaker load when external speaker is unplugged
- Direct out has speaker emulation frequency curve
- Direct out level control can act like a power attenuator allowing you to overdrive the output tube
- Cycle through presets or different groups of presets using the supplied external footswitch
- Preset zero is a true bypass from input to unbalanced direct output
- MIDI input for selecting presets or controlling any parameter
- DC tube filaments for reduced noise
- Free Windows software for controlling the amp using MIDI
