We wish you have as much fun working with it as we had during the development of this extraordinary equalizer.
Installation BEFORE SWITCHING ON POWER SUPPLY AND PQ, THE PQ MUST BE CONNECTED TO THE POWER SUPPLY WITH THE SUPPLIED MULTICORE LEAD. PAY ATTENTION TO A SECURE CONNECTION. The PQ and the external power supply should be situated away from heat sources and direct sunlight. PQ and power supply need sufficient air circulation. Avoid installation in environments exposed to vibrations, dust, heat, cold, moisture or electrical and magnetic fields.
Technology SPL High Gain Technology Additional construction features SPL is constantly pushing analog signal processing to its limits by combining the best possible components with perfectly optimized circuit design. As our latest achievement in this ongoing process, SPL‘s High Gain Series surpasses the hitherto accepted limits of audio signal processing and combines truly unparalleled analog sound quality with the control and convenience of digital units.
Key Functions Constant Q and proportional Q modes Master/Slave (unit link) mode Each frequency band consists essentially of two fully parametric equalizers: one for constant Q mode and one for proportional (or variable) Q mode, selectable per band. The PQ is the first equalizer to offer both modes, endowing it with double equalization power for demanding corrective and creative applications.
Key Functions Motorized potentiometers Bandwidth All of the PQ‘s potentiometers are motorized to accommodate the channel link and unit link functions. The adjustment range of the Frequency, Bandwidth and Amplitude potentiometers is evenly dispersed throughout the 300-degree movement area, ensuring smooth and continuous adjustments and extreme operational security. The high resolution of each respective value (e.g. Q from 0.1-3.
Channel Control Elements LINK FUNCTION SLAVE FUNCTION The link function couples the two channels for stereo applications. In link mode, one channel‘s controls will control both channels simultaneously. The slave function allows up to four PQs to be remote controlled by an optional remote unit (still in development) with an identical user interface.
Channel Control Elements/Connectors Overwriting a written preset CONNECTORS (rear panel) 1. Select a written preset you wish to overwrite, e.g. A003 („ A “ does not blink) Audio inputs and outputs are provided as balanced XLR connectors. 2. Press the Save key. The display shows „OVER“, prompting you to confirm overwrite Connect the included external power supply to the multi-pin socket in the upper left corner, ensuring that the connection is secure. 3. Press the Save key again.
Technical Specifications Input impedance (balanced): 20 kOhm External power supply (Welwyn precision resistors; transformerless) Output impedance (balanced): The PQ comes with an external linear power supply featuring a toroidal transformer for optimal audio quality and dramatically reduced inductive disturbance/interference. ‹ 600 Ohm (CMR trimmers, transformerless) Overload resistance: +34 dB (Band 1-5 = ON, B/C = 0) Harmonic distortion: S/N: @-30 dBu: @-20 dBu: @0 dBu: @+10 dBu: @+30 dBu: 0.
Warranty SPL electronics GmbH (hereafter called SPL) products are warranted only in the country where purchased, through the authorized SPL distributor in that country, against defects in material or workmanship. The specific period of this limited warranty shall be that which is described to the original retail purchaser by the authorized SPL dealer or distributor at the time of purchase. All remedies and the measure of damages are limited to the above services.
