ATT-S 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 preferhigh quality passive line stages control the interface between signal sources and amplifier. The passive control center is an obvious answer-simple, elegant, and precise.
Consistent with this philosophy, simplicity and quality were the overriding design goals for the ATT-S 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 H pad 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 the ATT-S.

  • 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.
  • H pad 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 HE-4304 having adequate gain to allow the use of passive control units with average source levels.
