EQ: the EQ in the Diamond Compressor is not a typical boost/cut treble control. Instead,
we've implemented a 'tilt' style EQ first introduced in the 1970's hi-fi market. The goal
of this eq is to provide subtle yet powerful spectral shifts in the overall frequency
balance, not just a simple dulling or brightening of the treble frequencies. You can think
of the EQ as a spectral 'see-saw' with the balance point fixed at a mid range frequency.
With the EQ in the center position, the EQ is completely flat. Turning the EQ
counterclockwise tips the balance of the 'see-saw' to- wards the low-end, with a gradual
increase in lows moving out from the midrange balance point toward the low end of the
frequency spectrum and a simultaneous gradual decrease in highs moving toward the
high end. Clockwise past the center position, the converse takes place, with a gradual
increase in highs moving out from the midrange balance point toward the high end
of the frequency spectrum and a simultaneous gradual decrease in lows moving toward
the low end. So, it works like a tone control, but it affects sound more musically.
!
VOL: this adjusts the overall output volume of the compressor. Once the relative levels of
compression and EQ are set, this control can be used to adjust overall clean vs. effect
levels.
ARCHITECTURE
The Diamond Comp Jr is architecturally identical to the original Diamond Compressor,
with a very simple analog signal path and optical driven resistor divider for optimal
transparency.
POWERING
The Diamond Comp Jr is designed to be powered from either a 9V battery (included), standard
9V negative tip DC power adapter or from a multi pedal power supply. It can also be powered
from negative tip supplies up to 18V for additional headroom as needed.
