THE MAIN OUTPUT
The output stage is identical with that of the Portico™ 5012, using
single-sided circuitry, driving a carefully configured output transformer
that can deliver a full +25dBu from the balanced and ground-free
secondary winding.
This maximum output level provides a large margin over and above the
likely maximum requirement of any destination equipment to which the
Portico™ 5032 may be connected. This is especially true when feeding
digital equipment!
Freedom from the interference fields that are inevitably present in any
control room is virtually guaranteed by the balanced, ground-free design
used in the Portico™ modules. My original classic modules always
used transformers, as do a number of other high quality vintage modules
still in current use.
High quality transformer connectivity has been used for many years,
enabling modular amplifier units to deliver the sonic performance for
which they are famous.
Bear in mind that human ears are very sensitive and can perceive
incredibly minute interference signals that are not part of the “desired”
signal. If unbalanced connections are used, great care must be exercised
to avoid ground loops and common signal paths. Reduced immunity
from various forms of interference can be tolerated (sometimes) but
usually results in a loss of that transparent musical resolution that we all
love.
However, the output of any Portico™ transformer-coupled module may be used with one side
grounded if necessary, for example to use with “Hi-Fi”, “consumer” or other unbalanced audio
gear, without degrading the performance of such devices. Care must be exercised when using
ancillary equipment to avoid overloading it.
THE BUSS OUTPUT
The Buss output is unbalanced and high impedance, and the BUSS connection is derived pre-mute.
It is intended for use with future modules in the Portico™ range which will be equipped with a
matching MIX or BUSS input.
The Portico™ 5032 BUSS output has dual, paralleled, TRS connectors that allow any number of
Portico™ modules to be mixed to the BUSS input on any of these appropriate modules using a
standard TRS patch cord.
When multiple Portico™ modules are configured in a console assembly, mixing busses will be
available at many points (beyond the ones traditionally expected), providing enormous flexibility.
More detailed descriptions with suggested block and system diagrams will be available in the future
on the Rupert Neve Designs website at www.rupertneve.com.
