5ch Selection Attenuator
The ideal audio component adds or subtracts nothing to the musical
signal. It is fully invisible to the ear.
Even the best active line amplifiers leave an audible mark on the
signal since there is no amplifier entirely free of distortion,
For this reason many listeners prefer high quality passive line stages
control the interface between signal sources and amplifier.
The passive control center is an obvious answer-simple, elegant,
Consistent with this philosophy, simplicity and quality were the
overriding design goals for the ATT-Q passive attenuators.
Like other WAVAC Audio Lab. products, the ATT attenuators are outstanding examples
of the manufacturing arts. The bodies of these instruments are sculpted
out of solid blocks of aluminum using the latest precision machining
technology, for distinctive styling and lifetime enjoyment.
A constant-impedance studio-grade attenuator provides the proper
termination at input and output and passes along the signal with
absolutely no audible coloration. The switches we selected for the
attenuator and source selector are high-reliability devices with gold
contacts and low dielectric molded wafer construction.
Luxurious precision machines stainless steel knobs slightly offset
from center offer a substantial feel and positive switch action.
Half-inlaied 18K solid gold dots provide tactile indication of selector
position and enhance the fresh,, contemporary visual design of
-ATT series passive attenuators consist of a high-quality molded wafer
switch with gold contacts serving as the source selector and a precision
attenuator for volume control.
-Attenuator circuit offers a constant source and load impedance of
10 kilo ohms for solid input/output termination.
-The ATT attenuators are ideally suited for high input sensitivity amplifiers
such as the EC-838 and EC-300B having adequate gain to allow the use of
passive control units with average source levels.
|Input/output impedance||10k ohms|
|Input voltage limit||5 volts|
