Produkt vergleichen SKU: N/A Categories: ,

The PQ from SPL is a fully parametric equalizer with five bands per channel and has a special EQ sound thanks to the 120V technology. The equalizer is designed as a completely separate dual-mono, two-channel EQ and allows two mono signals to be processed separately. However, both sides can also be linked via a link switch to control a stereo signal together via one side.

  • Maximum input and output level: 32.5dBu
  • Input impedance: 20kΩ
  • Output impedance: 75Ω
  • Common mode rejection (0dBu, 1kHz: >80dBu
  • Frequency response (-3dB): 10Hz – 40kHz
  • Crosstalk (1kHz): -108dBu
  • THD + N (+10dBu): 0.002%
  • Noise (A-weighted): -98dBu

Mastering Equalizer

The frequency bands can be switched on and off individually via the button below and offer the possibility to switch between Constant-Q and Proportional-Q with the blue button. In Constant-Q mode, the Q factor always remains the same with varying amplitude. This setting is useful to remove spurious frequencies.

If Proportional-Q is selected, the Q-factor behaves proportionally to the amplitude, i.e. the higher the amplitude, the smaller the bandwidth. At the smallest bandwidth setting, the signal to be processed can be boosted or cut by a maximum of +/-20 dB; at the largest setting, by a maximum of +/-2.8 dB. Due to this behavior, a very musical result can be achieved. The Q factor ranges from 0.6 to 15.

Each filter band has a maximum level change of +/- 20 dB. If one wants to make finer gain settings, the grid can be changed to ¼. This is especially predestined for mastering applications. Here, the maximum boost or cut is reduced to 5 dB.

The frequency division of the bands is selected so that individual frequencies can be processed with several bands. Thus the LF works at 10-330 Hz, the LMF at 33Hz – 1kHz, the MF at 128Hz – 2.1kHz, the MHF at 210Hz – 10.2kHz and the HF at 760Hz – 24kHz.

The PQ has an auto bypass for comparing the original signal and the processed signal. This automatically switches between the two signals so that you can focus on listening. The switching time window is set by the interval potentiometer.
If a channel button is pressed until it blinks, the respective side is set for stereo processing. The entire channel can be muted by briefly pressing the channel button.
