• Three fully parametric bands in accordance with the musically effective
proportional-Q-principle, Boost/Cut +/- 15 dB, Q 0.5 to 5; LOW band:10-250
Hz, MID band: 140 Hz-3,5 kHz, HIGH band: 940 Hz to 24 kHz.
• Sub-Bass-EQ (Cut/Boost +/- 14 dB, up to 200 Hz) with coil/capacitor filter
network that produces a penetrating and lucid deep tone spectrum. The
combination of Sub-Bass and Low filter for the processing of the bass
spectrum is very effective and opens a new dimension for sound creations.
• Air-EQ: the selected coil/capacitor-filter network provides a silky and airy
presence – especially in digital recording.
• The 3D-Enhancer intensifies the spatial impression of the stereo signal
without affecting the low frequency tonal components.
• Optional provision of input and output transformers from Lundahl: balan-
cing through transformer stages; the galvanic separation ensures high
operational safety. Tonal advantages are offered by the transformer coil.
This minimizes odd harmonic distortion and provides a silky top end.
• Generally coils sound less aggressive, but produce a rounder and more
powerful sound in the deep tone spectrum. This means they possess
advantageous musical properties which is why SPL prefers to install coils
in the filter area.
• Ground: Disturbances which could have an effect over the ground-runs
are minimized by the separation of the audio-ground from that of the
remaining apparatus. This leads substantially to a higher and ‘cleaner’
tonal quality (in the strictest sense of the word).
• Power supply: The toroidal transformer forms the basis for a clean power
supply throughout the circuitry.
Carefully select a place for setting up the Stereo Q. The unit should be
situated away from heat sources and direct sunlight. Avoid installation in
environments exposed to vibrations, dust, heat, cold or moisture. Keep the
unit away from transformers or motors or any other unit that could generate
large variations in power supply or cause electrical interferences. Do not
install the unit in proximity to power amplifiers or digital processors. You
may consider placing it in a rack containing other analog gear. Such place-
ment can prevent interference from Word Clock, Smpte, MIDI, etc.
• Do not open the case. You may risk electric shock and equipment damages.
• Leave repairs and maintenance to a qualified service technician. Should
foreign objects fall inside the case, contact your authorized dealer or sup-
port person.
• To avoid electric shock or fire hazards do not expose your unit to rain or
moisture.
• In case of lightning unplug the unit. Please unplug the cable by pulling on
the plug only; never pull on the cable. Never force a switch or knob.
• To clean the case use a lint-free cloth. Avoid cleaning agents as they may
damage the chassis. Manufactured in standard 19" EIA format, it utilizes two
rack units.
• Please support the back of the unit whenever it is being mounted into a 19"
rack (especially important when touring).
