SPL3220 Stereo Multiband Sound Processor / Loudness Maximizer / Limiter Controls (2) (3) (4) (5) (8) (6) (7) (1) (9) (10) (12) (11) (1) IN/OUT switch This switch activates the relays and engages both channels. The switch has a "hard-bypass" function. This means that when the switch is not depressed (OUT) or the unit is turned off, the input to output connections are direct. The IN/OUT switch is used to make direct A/B comparisons between source material and the proccesor's effected signal. (2) THRESHOLD control This control determines the threshold point of the Compressor/Leveller within a range from -40 to +20 dBu. The control function corresponds exactly to the threshold function found in simple broadband devices. (3) LEVELLER control This control is used to mix in the Leveller function. For the majority of applications, this control should be set to center position; the Leveller will compensate for varying levels in the programme material in order to achieve a consistent compression. (4) RATIO control The ratio control determines the ratio between the input and output level for all signals exceeding the threshold point. The control range can be adjusted from 1:1 to 6:1. (5) PROGRAM switch Withthis switch you determine the crossover frequency of the two bands between music (500 Hz) and speech (2 kHz). For complex signals we recommend the music (500 kH) setting whereas speech (2 kHz) is preferable to process individual vocals and instruments. (6) OUTPUT control The OUTPUT control allows for the increase or decrease of the output signal by a maximum of 20 dB. Thus, a level loss due to the compression or limiting process can be compensated for. (7) LIMITER control This control sets the absolute point by which the output signal is not allowed to go beyond. LO and HI LIMIT LEDs indicate the activity of the individual limiters. (8) GAIN REDUCTION meters The 8-LED GAIN REDUCTION meters indicate the current gain reduction applied by the individual bands within a range from 0 to 30 dB. (9) INPUT/OUTPUT LEVEL meters Depending on the setting of the IN/OUT switch, these 8-LED meters inform you either about the input or the output level and monitor them within a range -30 to +15 dBu. If not the IN.OUT switch is set to OUT. the input level is onitored, if set to IN, the meters read the output level. Th meter calibration is referenced to +4 dBu. (10) MAINS CONNECTOR Please use the enclosed mains cable to connect the unit tot the mains power supply. (11) INPUT A/B These are the SPL3220 Line Level audio inputs. (12) OUTPUT A/B These are the SPL3220 Line Level audio outputs. 3

IN/OUT switch
This switch activates the relays and engages both channels. The switch
has a ”hard-bypass” function. This means that when the switch is not
depressed (OUT) or the unit is turned off, the input to output connections
are direct. The IN/OUT switch is used to make direct A/B comparisons
between source material and the proccesor’s effected signal.

This control determines the threshold point of the Compressor/Leveller
within a range from -40 to +20 dBu. The control function corresponds
exactly to the threshold function found in simple broadband devices.
