3 Overview CS-5501 is a multi functional channel strip providing all necessary tools to process all kind of audio signals like vocals and instruments. CS-5501 comes with double EQ/compressor/limiter/gate/expander/deesser modules, saturation and thermal noise emulation. All modules have stereo placement options and are freely routable.

Click here to change the meter mode: PEAK (dB), RMS (dB), EBU ML (LU), EBU SL (LU) and VU (dBVU). RMS uses 600ms ballistics, VU 300ms. 5.2.3 Meter calibration Controls the reference level of Left/Right IN/OUT meter, in dBFS. (C) TBProaudio 2019 Page 8 of 31...
The red LED lights if signal is above ceiling level, regardless if clip protected is enabled or not. 5.3.2 Over sampling Incoming signal could be over sampled up to 2 times. Over sampling reduces magnitude/phase distortions near Nyquist frequency and let the filter sound much more "analogue". (C) TBProaudio 2019 Page 9 of 31...
5.4 Fader section 5.4.1 Input/output fader CS-5501 provides independent left/right faders for incoming and outgoing signal. Double click on the fader handle enables direct value input. 5.4.2 Input phase This control lets you invert the phase of incoming left and right signal 5.4.3...
The blue solo button indicates the solo state of the module. Click to solo/unsolo the effect module. Click with the right mouse button to show the effect in the GUI.Shift mouse click adds module to solo group. (C) TBProaudio 2019 Page 11 of 31...
5.7 EQ CS-5501 provides 2 independent EQ modules with 7 filters each. The filters are based on analogue design and minimize amplitude cramping near Nyquist frequency. This lets the filter sound much softer than normal digital filters. 5.7.1 EQ Module selector Select EQ1/EQ2 module from drop-down menu 5.7.2...
Each filter band (except LC/HC) can be monitored. 5.7.6 LC/HC Low-cut/high-cut filter with switchable filter slope. 5.7.7 HF/LF Peak/shelf filter with adjustable Q-factor. 5.7.8 HMF/MF/LMF Peak filter with adjustable Q-factor. (C) TBProaudio 2019 Page 13 of 31...
CS-5501 provides 2 independent compressor modules. The compressor squeezes the incoming signal depending on threshold and ratio. The compressor design is based on TBProAudio’s Impress and offers 3 different classical types: VCA stands for “Voltage Controlled Amplifier” and its compression behavior is based on PEAK, with fast attack and release.
Frequency: sets filter cut-off frequency 5.8.6.4 High-cut Off/On: enables high-cut Slope: sets filter slope Frequency: sets filter cut-off frequency 5.8.6.5 Link Toggles linkage of LC and HC frequency. 5.8.7 Compressor type VCA, FET or OPTO design (C) TBProaudio 2019 Page 15 of 31...
Release Sets release-time, in seconds. Higher values make the compressor longer working. 5.8.11 Auto release Enables program dependent release time calculation 5.8.12 Ratio Sets compression ratio. 5.8.13 Output Sets output volume, in dB. (C) TBProaudio 2019 Page 16 of 31...
5.8.14 Set mixing-ratio of compressed and original signal, from 0 % (dry) - 100 % (wet). 5.8.15 Gain reduction meter Shows current gain reduction, in dB (C) TBProaudio 2019 Page 17 of 31...
5.9 Gate/Expander CS-5501 provides 2 independent gate/expander modules. Gate/Expander opens only if the signal reaches a certain threshold. 5.9.1 Effect module selector Select effect module from drop-down menu 5.9.2 Off/On Enables the module. 5.9.3 Parameter link Links parameter of gate 1 and 2.
Slope: sets filter slope Frequency: sets filter cut-off frequency 5.9.6.5 Link Toggles linkage of LC and HC frequency. 5.9.7 Gate/Expander mode switch Toggles between gate and expander mode. 5.9.8 Threshold Sets threshold value, in dBFS. (C) TBProaudio 2019 Page 19 of 31...
Set release time, in ms. Higher values make the gate/expander longer open. 5.9.12 Range Variable range, in dB. In gate mode min value -72dB is treated as range off. 5.9.13 Attenuation meter Shows current signal attenuation, in dB (C) TBProaudio 2019 Page 20 of 31...
CS-5501 provides 2 independent deesser modules. Deeser is a kind of dynamic EQ. It compresses/expands the signal in a defined frequency range depending on the input/side- chain signal. The design is based on TBProAudio’s dEQ6, ensuring that any processing is done in a very musical way. 5.10.1...
Low-shelf/bell/high-shelf filter type. 5.10.8 Narrow band/wide band In wideband (WB) mode the deesser reacts on events in the full frequency range, in narrowband mode (NB) only on events around deesser centre frequency. 5.10.9 Listen (C) TBProaudio 2019 Page 22 of 31...
Sets centre frequency. 5.10.13 Attack Sets attack-time, in ms. Lower values make the compressor more responsive. 5.10.14 Release Sets release-time, in seconds. Higher values make the compressor longer working. 5.10.15 Ratio Set compression ratio. (C) TBProaudio 2019 Page 23 of 31...
Set static filter gain, in dB. 5.10.17 Output Sets output volume, in dB 5.10.18 Range Limits the gain reduction to a certain range. 5.10.19 Gain reduction meter Shows current gain reduction (blue) or gain boost (green), in dB. (C) TBProaudio 2019 Page 24 of 31...
CS-5501 provides 2 independent limiter modules. The limiter keeps the signal below a certain “ceiling” level. The design is based on TBProAudio’s LAxLimiter and therefore ensures maximum loudness paired with very low aliasing. Please to note that Limiter introduces 128 smp latency, which is usually compensated by the DAW.
Sets the release time, in ms 5.11.8 Auto release Enables program dependent release time calculation. 5.11.9 Ceiling Set the maximum output level, in dBFS. 5.11.10 Gain reduction meter Shows current gain reduction, in dB. (C) TBProaudio 2019 Page 26 of 31...
5.12 Saturation CS-5501 provides a saturation module. Saturation adds odd or even harmonics to the signal. The saturation effect emulates several tubes with odd and even harmonics. 5.12.1 Effect module selector Select effect module from drop-down menu 5.12.2 Off/On Enables the module.
Controls the amount of odd harmonics added to the signal, in percent. 5.12.7 Even Controls the amount of even harmonics added to the signal, in percent. 5.13 Thermal noise emulation CS-5501 provides a module to emulate thermal noise of analogue channel strips. 5.13.1 Off/On Enables the module. 5.14 Info menu 5.14.1...
AB-LM also offers more advanced options, including advanced measurement modes and snapshots. For the more advanced features of AB-LM, please see https://www.tb- software.com/TBProAudio/ab_lm.html (C) TBProaudio 2019 Page 30 of 31...
7 Demo mode versus Registered mode In demo mode (without registering) the plugin mutes audio every 90 seconds for a short period. This could be circumvented by clicking on the "TBProAudio" logo within 90 seconds. 8 Activation After purchasing the license key, unpack the key to a convenient place on your PC (e.g.
