FAQ - Direct Connection to the Pickups
All Audere preamps feature a direct connection to the pickups.
The pickups are directly connected to the
internal transistors of the amplifier.
Most other preamps have an AC connection to the pickup and a 2nd
one at the end of the preamp.
Normally somewhere in the signal path of an on-board preamp there
will be at least one DC to AC translation point. This translation point
is required because if only 1 battery is used the designer must split
this voltage to amplify both polarities of the pickup signal.
The Audere preamp has 1 translation point and we
have moved this point to the end of the preamp instead of at the
start of the preamp.
By moving the translation point to the end of the preamp we have
a low impedance signal to drive the capacitor. This means any distortion
created by the capacitor will be reduced. Capacitors come in different
quality levels at different price points. Most of the non-ideal behaviors
within capacitors are related to the dielectric materials that can
be used and still keep the capacitor a reasonable size.
In addition to placing the capacitor at the end of the circuit, we've
chosen for a better quality capacitor than is typical.
Note on installation:
We separate the pickup common from ground, which is an uncommon
wiring requirement.
We supply the pickup common connection with a virtual ground voltage
which is about 1/2 the battery voltage. If you follow our wiring instructions
you should have no problems, just make a note that this aspect of
the wiring is different from other preamps.
The direct connection to the pickups is uncommon technique
which allows a cleaner sound to be obtained from the pickups
but the wiring is slightly non-standard so the installer must follow
the provided instructions.
