1 Introduction
The Pullet is a two channel passive equaliser which has no
active electronic components included in its design. This means
that when using the Pullet it is necessary to use a pre-amp in
order to provide the make up gain required. The Pullet has been
designed with the Earlybird pre-amp in mind but although it is
optimised for use with the Earlybird, care has been taken to
ensure that the Pullet will give excellent results when used with
any suitable pre-amp available. In this respect the Pullet
becomes very versatile because the Eq facilities provided can
be combined with the sound quality of the chosen pre-amp.
The Pullet will give up to 21 dB of boost or 17dB of cut
simultaneously to a choice of 11 boost frequencies, with
variable Q, and 11 cut frequencies. We have also included an
“air” control to give access to high frequencies.
As usual Thermionic Culture has taken care to ensure that the
distortion and noise level introduced by the Pullet are kept as
low as possible.
