SPL / PQ All Black

A 5-band mastering equalizer that allows you to switch between two different Q values ??for each band.

*This product requires an AC115V 50/60Hz outlet. Please note that it will not function correctly with a standard household outlet (AC 100V) without voltage boosting.


Promotional-Q Mode / Constant-Q Mode

Each frequency band consists of two full parametric equalizers. One is Constant-Q Mode, and the other is Promotional-Q Mode. You can select either mode for each band. In Constant-Q Mode, the selected bandwidth does not affect the cane, making it suitable for correction applications (e.g., removing unwanted frequencies).

In Promotional-Q Mode, the cane decreases as the bandwidth increases, and conversely, the cane increases as the bandwidth decreases. Bandwidth? At the narrowest setting, the maximum cane width reaches +/-20dB, while at the widest setting, it decreases to +/-2.8dB. The Professional-Q mode allows for intuitive operation, making it suitable for creative sound-shaping applications.

Frequency

Each channel has five frequency bands. All bands are fully parametric and can be independently switched on/off. The operable frequency range is 10Hz to 24kHz.

Frequency Range

LF (Low Frequencies): 10Hz - 330Hz

LMF (Low Mid Frequencies): 33Hz - 1kHz

MF (Mid Frequencies): 128Hz - 4.1kHz

HMF (High Mid Frequencies): 310Hz - 10kHz

HF (High Frequencies): 760Hz - 24kHz

Q

Adjusts the bandwidth. In Proportional-Q mode, the bandwidth is adjusted from 0.08Q to 5.8Q; in Constant-Q mode, it is adjusted from 0.6Q to 15Q.

1-4 Gain

Turning on the 1-4 Gain switch increases the potentiometer's adjustment range from a maximum of +/-20dB to +/-5dB. This allows for finer adjustments for master linking.

Auto Bypass

When objectively evaluating processed audio, the Auto Bypass function allows you to automatically switch between the original signal and the processed signal at a set interval, rather than manually. This is a significant advantage, as it allows for more focused evaluation without moving from your monitoring position.

Link

When the Link function is turned on, some of the settings made on one channel (LF, LMF, MF, MHF, HF on/off, Prop-Q) will be reflected on the other channel as well.
