SPL digital audio processors are designed in cooperation with Introduction Spectral Design of Bremen, Germany, who are responsible for the DSP programming. Concept: The SPECTRALIZER is the first digital harmonics processor Re-synthesizing second and employing a new process which allows you to re-synthesize third harmonics separately second and third harmonics separately, and with full control over their amplitude. The SPECTRALIZER benefits from SPL's expertise in psycho-acou- stic principles an

the small timing glitches that would otherwise occur when switching the process in and out. Up to 99 presets can be stored and changed using a MIDI program change command. Display: The SPECTRALIZER is equipped with two PPM-meters that feature high resolution in the important region immedia- tely before 0dB. Clip-LEDs indicate digital clipping, while the first Input and Output LED of each PPM-meter functions as a signal present indicator PPM metering to confirm that a digital signal is present a

Rear Panel Spectralizer Before connecting the SPECTRALIZER switch the power off at all Connections connected units. The rear panel provides AES/EBU- and S/P-DIF-inputs and outputs. Any additional channel, status and user-bits are passed through unaltered, and the outputs can be used at the same time if required. The SPECTRALIZER operates with 24 bit word width. It accepts 16 bit and 20 bit inputs and will create output signals accor- ding to the input resolution. For synchronisation purposes WO

Set MIX to 50%. You will notice an increase in high frequencies above 1 kHz (starting position FREQUENCY). 3. Set DENSITY to 1, to increase the audibility of the harmonics in the next step. 4.

FREQUENCY sets the starting frequency of the highpass filter. 3 Frequency Above this frequency second and third harmonics are being generated. The highpass filter can be varied between 1kHz and 7 kHz in steps of 500 Hz. MIX controls the mix level between the processed and the 4 Mix unprocessed signal. The control range is 0 % to 100 %. The MIX encoder is equipped with an „alpha-dial“ logic. Turning the encoder rapidly causes the values to jump in steps of 10, whereas turning the encoder slowly c

The control range is 0 % to 100 %. The 2ND HARMONIC encoder is equipped with alpha-dial logic. Turning the encoder rapidly causes the values to jump in steps of 10, whereas turning the encoder slowly causes the values to proceed in single increment steps. If the need arises to make the harmonics more audible use the DENSITY control (see DENSITY, 7) to increase their loudness. The 3RD HARMONIC encoder controls the intensity of the added 6 3rd Harmonic third harmonics which are being generated ab

DENSITY increases the loudness of the generated harmonics by 7 Density applying different “compression ratios”. The control offers six positions. Adjustment: If DENSITY is set to 0, the generated harmonics have low intensity even at high values for 2ND and 3RD HARMONIC. The increase in high frequencies is mostly created by the highpass filtering, which applies a shelving equalizing above the adjusted FREQUENCY encoder (see FREQUENCY, 3). Increasing DENSITY to 1 or 2 will increase audibility of

In order to increase operation safety only send the necessary MIDI data to the SPECTRALIZER. Unnecessary information might lead to system failure. You can use MIDI to create a MIDI fade out, if you are working with a digital console that does not provide master inserts. The UP and DOWN LEDS illuminate indicating that a volume change command is received. You can also switch between presets with the MIDI program change command. This can especially be useful, when you are mastering a song, for exam
