Both the Black2 and Green2 use a three piece OTL cantilever that has a
Grado specific diamond mounted on a brass bushing. The Green2 are hand
selected from Black2 production runs which meet higher test
specifications. Approximately 15% of the run usually exhibits these
specs and become a Green2.
Grado’s OTL, or optimized transmission line, technology provides an
ideal transfer of signal from the surface of the LP to the generator of
the system. This technology rejects unwanted resonances and lowers
distortion preserving the fundamental and harmonic frequencies of the
music. This also helps keep noise generated by the motor system in the
cartridge to a minimum.
Grado’s OTL stylus/cantilever design
makes records sound quieter, improves the height, width, and depth of
the soundstage, and present more detail than previously obtainable.
Black2 & Green2 are all hand assembled by our team in Brooklyn,
with some builders having over 25 years of experience. With the recent
development of the highly received Lineage Series of cartridges, we were
able to have a trickle down of technology and bring a new technique to
the Black2 & Green2. This updated series of cartridges offers
excellent tonal balance, dynamics, and realism, for a most rewarding
reproduction of vocals and instruments. Our coil winding techniques,
using ultra high purity copper wire which were honed during the
development of the Lineage Series, have let the electrical circuits
achieve unison between the four coils in each phono cartridge. This
allows for a precise balance between channels and accurate stereo
As in all Grado phono cartridges the Black2 & Green2 are powered
by a twin magnet system that optimizes the balance between stereo
channels. All internal magnetic circuit parts are held to extremely high
tolerances creating the desired stereo imaging. Grado’s patented
Flux-Bridger design allows the Black2 & Green2 to have one of the
lowest effective moving mass generating systems while creating an
excellent balance throughout the full frequency range.
The development of the Epoch in the Lineage Series gave us an
in-depth experience with using an outer housing as a damping device.
This led to the creation of a process which de-stresses the chassis and
dissipates unwanted energy & resonant frequencies, allowing the
desired signal to travel freely.
