This two channel digital De-esser / Compressor features linear-phase crossover filters covering the whole audio band. [. . . ] When using parallel compression, the DS1-MK2 is able to run in frequency selective or in full band mode. listen to the filtered signal for optimal crossover setup. Read this quote from Bob Katz from the Mastering Webboard: "You want a patch that compresses without stomping on the attacks at all, preserves transients but gives you great inner detail?You have one control, one control only, and that is the output level of the compressor [gain peak / over hold input meter output meter Input Comp. + Pre-Limiter Gain Safety x Limiter Output Gain x Output Graphic 10: Parallel full band compression Parallel full band compression: As can be seen in the schematic (Graphic 10), the input signal and the compressed signal are added together. The gain makeup value can be used to control the amount of compressed signal. The pre-limiter gain can be used to scale the mix before limiting. makeup], the `sidechain'. You can bring out inner details without losing breathing, and hardly affecting the upper dynamics at all. Variations: Use it like the Dolby Spectral Enhancer, by split band [parallel] compression, so that (for example) high frequency inner details at low output meter peak / over hold input meter Input Crossover band pass Comp. + Pre-Limiter Gain Safety x Limiter Output Gain x Output Graphic 11: Parallel band selective compression Parallel band selective compression (Graphic 11): To add even more subtle compression, the compressed signal can be filtered before compression. " The last paragraph refers to parallel band selective compression (crossover in highpass mode). - Weiss Engineering Ltd. , Florastr. 42, CH-8610 Uster +41 1 940 20 06 2 +41 1 940 22 14 8 http://www. weiss. ch * weiss@weiss. ch Page 12 of 29 OPERATING INSTRUCTIONS FOR GAMBIT DE-ESSER/COMPRESSOR DS1-MK2 OPERATION Presets The DS1-MK2 has easily accessible presets () for a quick setup which can then be refined and adapted to the programme being processed. These presets are grouped according to their function: De-Esser: Four applications for high-frequency transients removal. Limiter: Three settings for loudness maximising experiment with the transfer curve parameters for a programme optimised result. The last setting uses the crossover to select the low-band and applies a small gain, hence , , bass boost". Snapshots Snapshots are copies of the DS1-MK2 parameter settings. This allows recalling complete set-ups including all parameters and controls settings. Snapshots can be recalled from the front panel or by remote control (e. g. To see workspace status refer to the status display (, see Status Display p. A-B Comparison You can compare two settings by using the two workspaces "A" and "B". Restore a snapshot or simply adjust parameters in one workspace, then switch to the other to compare. To copy workspace "A" to "B" or vice versa, press the "copy" key and select an option (Graph 12). Dither The DS1-MK2 v2. 0 is able to apply POW-R type dither algorithms to avoid distortion when requantizing from 24bit to 16bit or 20bit output word length (see TECHNICAL DATA for dither specifications). To see dither status refer to the status display (, see Status Display p. Word Length To set output word length, press key D and select the appropriate wordlength. This leads to the menu where the type of POW-R dither can be chosen (see TECHNICAL DATA for dither specifications). Also selectable is: Auto-Blacking If auto-blacking is activated by marking the "0 IN 0 OUT" option, dither will be turned off if the input signal is zero As soon as the input signal changes, dither will be turned on again. [. . . ] Please also read the appropriate pages in the DS1 / DS1-MK2 manual to have a proper understanding of the sidechain process. The test signal is a repeating sine wave burst with a certain "on" and a certain "off" level. The frequency of the sine wave is above 10kHz (period less than 100 s), so there is no influence of the sine wave frequency on the timing behaviour. For the static parameters a threshold of -20dB, a 1000:1 ratio and no softknee have been chosen.
