5016 MIC PRE/DI

THE MIC PRE 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™ 5016 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 balanced and high impedance, and the BUSS connection is derived pre-mute. It
is intended for use with modules in the Portico™ range which are equipped with a matching MIX
or BUSS input.
The Portico™ 5016 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 are available in the future on
