| High-end sound and
specifications
Compact - easy to mount in
most existing audio amplifiers
as DIY upgrade.
Audio volume controls with
very accurate attenuation and
tracking (0.05dB).
Resistor network using
Surface Mount Device (SMD)
type of resistors for short
signal path and very low
series inductance and stray
capacitance
Available as master volume
control with 60dB attenuation
range (1, 2, 4, 6, 8 decks) and
as individual channel fine
adjustment control with 0.5dB
level change between each
step (only available with 1
deck).
DESCRIPTION
The CT2 Audio Volume
Controls are high quality
stepped 24-position
attenuators. They were
designed for maximum sonic
quality, accuracy and
reliability. This makes them
equally suited for audiophile
applications and for
professional applications.
Available as master volume
control with 60dB attenuation
range (1, 2, 4, 6, 8 decks) and
as individual channel fine
adjustment (CT2-10k-1/fine)
with 0.5dB level change
between each step (only
available with 1 deck).
Their series resistor networks
consist of 23 non-inductive,
low noise, SMD metal film
resistors.
The layout of the PC Boards
and the choice of SMD
resistors have reduced the
signal path to a minimum
length (typical five times
shorter than conventional
stepped attenuator designs
with leaded resistors). The
PCB design combined with the
special resistors also account
for the very low series
inductance and the very low
stray capacitance.
The result is a bandwidth
beyond even the most
demanding
audiophiles’
requirements.
There has been special care
taken to ensure the durability
of CT2. Therefore, all contacts
and PCB traces are gold
plated to prevent any
corrosion. As a result, the
CT2s will maintain their
specifications after long time
of use even in hot and humid
environments.
The rotary switch itself is a
gold plated high precision
switch manufactured in
Switzerland.
