Acoustical Systems arche User manual

5D headshell
owner’s manual

The arché is the 1st universal headshell
ever to enable the user to adjust each
and all settings of cartridge alignment
right at the spot - at the headshell /
cartridge - and independent from each
other.
Further it is the 1st high-end headshell
to offer the paramount important ad-
justments of SRA and VTA to be made
at the cartridge itself - while keeping
tonearm settings stable and unaltered.
In its design, as well as in its choice
of materials and manufacture the arché
goes new ways and opens up new
Introduction horizons in adjustment and sonic
performance.
Designed and manufactured like an
expensive tonearm, the arché maximizes
rigidity, energy transfer and adjustment
options. Featuring a composition of
non-parallel surface construction,
unique ways of inner dampening and
prime materials.
Triple-tempered aerospace grade alumi-
num, structure fortied micro titan tubes,
nano ball-plungers and special custom
made stainless steel screws are the main
components of an unique design. A
design which serves as the very best pos-
sible partner and link for any cartridge
and any tonearm with a SME-bayonet.

Variants
The arché is available in a choice of
prime nishes :
- satin nish - ceramic silver
- satin nish - 24 ct gold
- satin nish - rhodium

Adjustments 1. Overhang
In the arché overhang can be adjusted
at 2 different spots.
You may use the prolonged screw slots
for mounting the 1/2” cartridge.
Furthermore you can slide back and
forth the whole cartridge at the SME
collar afterundoing the collar-xing
screw.
Both options do allow for approximate
5-6 mm adjustment each.

2. Offset angle
The setting of the required offset angle
also can be made in the prolonged
mounting slots.
The prolonged slots are a bit wider
than necessary to accommodate a
M 2.5 screw.
Thus they allow for about +/- 3-5°
offset-angle to be adjusted by moving
the cartridge to the required position.

3. Azimuth
Azimuth can be adjusted by rst
undoing the collar-xing screw.
Now you can rotate the complete
headshell around the collar in both
directions by +/- 3-4°.
There are helping lines at the back of
the arché to nd certain direction and
spots.
Make sure to fasten the collar screw
again after azimuth adjustment.
