Loudness Maximiz er Model 9632 Manual by Hermann Gier V ersion 3.1 – 9/1999 The information in this document has been carefully verified and is assumed to be correct. Howev er Sound P er formance Lab (SPL) reser ves the right to modify the product described in this manual at any time.
3 Co n te n t s Dear customer , Thank you f or the confidence you hav e shown towards Sound P er formance Lab b y purchasing the SPL Loudness Maximizer . Y ou hav e decided to use a tool of high per formance which sets y ou in the position to have faster succ ess and a better sound quality in your music productions and pre-masterings.
Loudness Maximizer 4 SPL ’ s digital audio processors are designed in cooperation with Spectral Design of Bremen, Germany , who are responsible for the DSP programming.
Opera tion Safety Indications and Metering: The Loudness Maximizer is equipped with PPM meters for input and output that show the signal lev el with maximum resolution (0.
Loudness Maximizer 6 Before connecting the Loudness Maximizer switch the po wer off at all 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.
Loudness Maximizer 7 Quick Star t F low Char t The signal analysis computes control data for the Compressor and Limiter and calculates the P ossible as well as the Done loudness increase Possible: The.
Loudness Maximizer 8 Relay hard-bypass for AES/EBU input and output Adjusting the desired increase in loudness C ontr ol Elements The ACTIVE function switches the Loudness Maximizer on or off . The illuminated LED indicates that the proc essing has been activated .
Diagram The Loudness Maximizers Limiter does not produce harmonical distortion Defining the way the Limiter sounds and defining if invalid samples are allowed or not. Y ou can gain more loudness and also star t to manipulate sound when you choose other than the initial settings for SOFT-HARD (see 3) or MORE DENSIT Y (see 4).
Loudness Maximizer 10 With the MORE DENSIT Y control you can change the principle behaviour of the control loop of the L oudness Maximizer . This parameter describes the Compressor-to-Limiter proportion. In addition, internal rules and algorithms will be changed, too.
The Input and Output LED chains are PPM (peak level) meters . By evaluating both LED chains an appro ximated effective loudness increase can be estimated . The LED chains have a very fine resolution before 0dB . The 0dB position is actually showing 0.
Loudness Maximizer 12 Storing a preset: Depress Store for1 sec. – LED flashes; use Up/Down to select preset number; depress Store again – LED goes out, preset is stored Applying a preset: Depress .
1. Sof tware version and date 2.Selecting inputs: The Loudness Maximizer automatically searches f or an input signal. If both inputs are connec ted the AES/EBU input will be selected first. If you want to select the S/P-DIF input you have to call up the INFO pages: AES/EBU input detected.
14 Or: no S/P-DIF input detected. Press APPL Y (if S/P-DIF is detected): S/P-DIF input with wordclock detected. Or: S/P-DIF input with wordclock detected. 3. Displaying the detec ted sample frequency: The Sample F requency will be detec ted automatically .
6. Displaying the Channel Difference Error flag: No = no error detected; Y es = error detected. 7. Setting or erasing the Copy-Prohibit flag: No = flag erased or not set; Y es = flag set.
Loudness Maximizer 16 11. Selec ting a MIDI channel: Depress APPL Y to step from channel 01 up to channel 16. In order to increase operation safety only send the necessary MIDI data to the Loudness Maximizer . Unnecessar y information might lead to system failure.
Loudness Maximizer 17 Adjusted output levels will be st ored and will be active the next time you boot the Loudness Maximizer . If you recognize that your unit does not maximize to full scale, please check the Output Lev el parameter first.
Loudness Maximizer 18 Specifications (1) AES/EBU is defined for levels from 2 V to 7 V Measurements AES/EBU: 4,4 V with load (2) S/P-DIF is defined for levels from 200 mV to 700 mV Measurements S/P-DIF: 500 mV with load Subject to change without notice.
Loudness Maximizer 19 SPL electronics GmbH (hereaf ter called SPL) products are warranted only in the country where purchased, through the authorized SPL distributor in that country , against defec ts in material or workmanship.
