We strongly recommend that you connect your Wadia 27i Decoding Computer directly to
your power amplifier. Even if you purchased your Wadia 27i with the intention of connecting it
through a preamplifier, we suggest that you experiment with direct connection to your amplifier.
Many listeners are surprised by the improvement in performance over even the most expensive
preamplifiers. If you would like more information about getting best performance from a system
without a preamplifier, contact your Wadia dealer.
To connect your Wadia 27i to a power amplifier, ensure that your power amplifier is turned off,
then connect your analog interconnects from the Wadia 27i balanced or unbalanced analog
outputs to the amplifier’s inputs.
While the Wadia 27i Decoding Computer was designed to be used without a preamplifier,
it will provide excellent operation in a conventional system with a preamplifier. Simply connect
the analog outputs from the Wadia 27i to a pair of linelevel inputs on the preamplifier.
When using a preamplifier, disable the Wadia
27i
volume control by setting it to its
maximum volume.
Best performance is obtained when the Wadia Digital Volume Control is operated close to its
maximum level. If you find that your critical listening occurs with the volume lower than 65 on
the display, then it may be advantageous to attenuate the output. This is done by manipulating
a set of internal switches. If you would like to change the output level, consult your dealer.
The
Wadia
27i
output level is factory set at 4.2 volts which will accommodate the most common
range of system sensitivity without needing
adjustment.
