Recent developments in sound measurement techniques have revealed the limitations
of existing graphic equalisers. The wealth of data that such equipment can provide for
the users requirements – feedback suppression, increased headroom, room equalisation/
compensation can no longer be adequately provided for with a simple graphic equaliser.
The Apex PE MKII is the solution, providing a tool which both enables maximum correction
whilst shaping the response to your specific requirements, combining a full graphic equaliser
with a complementary parametric equaliser/notch filter.

FEATURES:
Electronically balanced input with a balanced floating output stage.
All potential overload points are continuously monitored by an extremely fast “peak-peak”
overload detecter circuit, followed by a “peak-stretching” circuit for clear indication of overload
conditions.Reliablilty is the hallmark of any product, and the mechanical integrity of the components
housing is the vital prerequisite. Sophistical CAD programmes and advanced engineering concepts
have been applied to the chassis design to eliminate the stress and torsional movements which can
damage the electronics.Special attention has been given to the purity of the signal path.The musicality
of previous designs of Apex equalisers has been well appreciated by users, and the PE continues this
tradition, noise and distortion are significantly better than 16-bit digital.Fine-tuning your system is essential.
The “vernier control” provides adjustment refinement on an unprecedented scale.In the event of power failure
to the unit, a failsafe relay links the input to the output ensuring that signal continuity is maintained.
