INSTALLATION AND CONNECTIONS [ INSTALLATION ] The following counsels must be observed to maintain safety and electromagnetic compatibility performance in order to obtain the best possible performances by your Cyclone. Earthing & Power Connections Since all the signals are referenced to earthing system, it's very important that it's clean and noise free. The best way to do an earthing system is to use a "star fed" instead of "daisy chain".
[ CONNECTIONS ] All connector shells should be of metal construction in order to provide a screen when connected to the console. The Cyclone deserves to be operated with high quality twisted-pair audio cables to develop its full audio performances.

FUNCTIONAL DESCRIPTION [ Cyclone Mono Input Channels ] The Cyclone is supplied with all the connections which pro users deserve to connect every kind of signal sources to Cyclone inputs. Insert This unbalanced 1/4" jack connector has been designed to be used as insert point, breaking the signal path immediately after the preamp section and before the EQ section to allow the pro user to insert a dynamic compressor, a parametric EQ, as well as other ancillary equipment.
[ Cyclone Mono Input Channels ] We perfectly know the importance of the preamp section, a good preamp section will allow the sound engineer to work with maximum dynamics, an exceptional signal-to-noise ratio... then to be able to use EQ, external dynamic controls and other ancillary equipment to shape its own sound! The Cyclone preamp section features all the useful controls to accurately manage the sound source in the most versatile way.
[ Cyclone Mono Input Channels ] We provided a very versatile EQ circuit with two sweep filters to satisfy professional users demand. Thanks to the wide overlap section of the 4 filters, this EQ allows to shape in a very efficient way the sound of all the sound sources which the sound engineers has to manage. HIGH gain It's a shelving filter giving the user a continuous adjustment of boost and cut from +15dB to -15dB @15KHz.
[ Cyclone Mono Input Channels ] At LTO we thought that you deserve a very versatile auxiliary section. So we provided you six auxiliary sends. These AUX sends can control the signals level which come from AUX output, but they have no effect to the main output. AUX 1 AUX 2 - The AUX 3 send level can be adjusted from - 0dB up to +10dB. - AUX 3 +15 0dB 8 The AUX 2 send level can be adjusted from - -15 8 up to +10dB. 0dB - 0dB AUX 4 +10 AUX2 +10 AUX3 +10 AUX4 up to +10dB.
[ Cyclone Mono Input Channels ] The assign section is useful to manage the output assignment to several outputs, listen "in Solo" a channel and mute or not a channel signal. OUTPUT Assign to 1/2, 3/4, L/R These switches allow the sound engineer to address the signal to selected audio path. The odd/even numbered switches are used to send the signal to sub-groups while L/R switch sends the signal directly to Main Mix output.
[ Cyclone Stereo Input Channels ] Each Cyclone is supplied with four stereo input channels. These channels are ideal for stereo signals but we included the same circuit of mono inputs, with discrete preamp level section and low-cut filter. So the sound engineer has the choice to use a mono signal and a stereo signal outputs in the same channel in different times without being obliged to change the GAIN control! RIGHT This balanced input connector has been designed to accept line inputs up to +22dB.
[ Cyclone Stereo Input Channels ] The Cyclone preamp section is fully featured with all the useful controls to manage the sound source. There are two different preamp input path for mono or stereo signals, the latter features just GAIN while the mono preamp input is regularly featured like any other mono input.
[ Cyclone Stereo Input Channels ] Stereo sources are generally keyboards outputs, pre-mixers, etc., so the signal deserves few EQ adjustments. For this reason we choose for the Cyclone stereo channels a four band fixed EQ. HIGH gain 0dB HIGH 12KHz It's a shelving filter giving the user a continuous adjustment of boost and cut from +15dB to -15dB @ 12kHz. -15 +15 0dB MID-H MID-H It's a peak/dip filter giving the user a continuous adjustment of boost and cut from +15dB to -15dB @ 3kHz.
[ Cyclone Stereo Input Channels ] At LTO we thought that you deserve a very versatile auxiliary section. So we provided you the same six discrete auxiliary sends of mono channels, with independent level controls. AUX 1 The AUX 1 send level can be adjusted from - up to +10dB. 0dB AUX1 up to +10dB. AUX 3 - 0dB - 8 The AUX 2 send level can be adjusted from - 8 AUX 2 0dB up to +10dB. - 8 The AUX 3 send level can be adjusted from - 0dB AUX 4 AUX2 +10 AUX3 +10 AUX4 up to +10dB.
[ Cyclone Stereo Input Channels ] The assign section is useful to manage the output assignment to several outputs, and also to PFL or MUTE a channel signal. OUTPUT Assign to 1/2, 3/4, L/R These switches allow the sound engineer to address the signal to the selected audio path. The odd/even numbered switches are used to send the signal to sub-groups while L/R switch sends the signal directly to Main Mix output.
[ Cyclone Master Section ] The master section is the richest section of the mixer with plenty of inputs, outputs and control switches. Here's a detailed description of each connector. RTN1 LEFT (MONO) & RTN1 RIGHT These balanced connectors are for stereo auxiliary return 1. Connecting a plug just to LEFT input it will act as a mono effect return. RTN2 LEFT (MONO) & RTN2 RIGHT These balanced connectors are for stereo auxiliary return 2.
[ Cyclone Master Section ] AUX 1 OUT This unbalanced1/4" TRS connector is for auxiliary 1 send. AUX 2 OUT This unbalanced1/4" TRS connector is for auxiliary 2 send. AUX 3 OUT This unbalanced1/4" TRS connector is for auxiliary 3 send. AUX3 OUT AUX2 OUT AUX1 OUT AUX5 OUT AUX4 OUT AUX 4 OUT This unbalanced1/4" TRS connector is for auxiliary 4 send. AUX6 OUT AUX 5 OUT AUX SENDS This unbalanced1/4" TRS connector is for auxiliary 5 send.
[ Cyclone Master Section ] LIGHT This 4-pin XLR connector must be used to connect 12V DC lamps(Max 8W). This input is for a talkback microphone, Which will be managed by SOURCES section. 1 4 TALKBACK INPUT 3 TALK BACK INPUT 2 LIGHT 12VDC 8W max HEADPHONES OUT HEADPHONES OUT This socket will send out the control Room signal to the headphone. CTRL LEFT & RIGHT OUT LEFT These 1/4" sockets are used to send the control room signal to the studio monitor speakers or a second set of PA.
[ Cyclone Master Section ] TAPE IN LEVEL This pot will give the sound engineer the ability to manage the tape return signal level from - up to +10dB. OUTPUT Assign to 1/2, 3/4, L/R TAPE IN 0dB LEVEL GR 1 2 - GR +10 8 These switches allow the sound engineer to address the signal to the audio path which he wants to. The odd/even numbered switches are used to send the signal to sub-groups (then you can send their signal to L/R outs) while L/R switch sends the signal directly to Main Mix output.
[ Cyclone Master Section ] The aux send section is useful to control the overall level of the send to a monitor speaker or to an effects unit. Generally pre-fader is used for monitor purposes, allowing the sound engineer to set a level that's independent by channel fader setting. In this way the control will be much more accurate and the sound engineer doesn't risk unwanted feedback when, for example, he raises the level of the lead singer. Post-fader sends are better suited for FX sends control.
[ Cyclone Master Section ] The group section contains all the controls for level and soloing the group signal. The most important feature is the To L/R switch that allows the sound engineer to use in a different way the group signal. Generally this switch is released when the sound engineer wants to record some grouped signals, while the switch is pressed when the sound engineer wants to use the groups signal as a part of the signal to be addressed to stereo mix.
[ Cyclone Master Section ] Master section controls are the most important in every mixer, these controls affect the overall level, the headphone listening, control room, Talkback and so on. LEVEL This is the main level control for the talkback and oscillator section. TALKBACK / OSC 0dB ON LEVEL AUX GR - 1 2 +10 8 This switch activates and sends the talk-back/osc signal to its selected outputs.
[ Cyclone Master Section ] CONTROL ROOM level 0dB LEVEL This stereo pot will give the sound engineer the ability to carefully manage the CONTROL ROOM level from - up to +10dB. +10 8 - CONTROL ROOM HEADPHONE MONITORS level 0dB This stereo pot will give the sound engineer the ability to carefully manage the HEADPHONE MONITORS level from - up to +10dB.

CYCLONE TECHNIQUE & TROUBLESHOOTING This section of the owner's manual gives you some basic information about the technique how to get the best performances from your Cyclone. Of course there are several tricks and tips. The last part of this chapter is about troubleshooting. GAIN settings You should use the channel input gain to obtain the best operating level for the console. If the gain level is too low the best signal to noise ratio won't be achieved.
However (and this is a big however), there are still sources of potential problems. The Cyclone is able to operate at levels up to +21dBu on both the insert send and return. If the maximum input level of the compressor is less than +21dBu then it is possible to overload the input of the compressor. The only way to solve this situation is to drop the channel input gain so that the input level of the compressor will not overload.
EQ DIAGRAM In recording studios as well as on stage, the versatile Cyclone EQ section is a valuable sound tool. Its controls will allow the sound engineer to modify the frequency contour of sound to shape the character of instruments to obtain the sound he wants to. The following frequency table gives you some basic information about the fundamental frequencies of some musical instruments and of the human voice.
Assign keys These switches allow the sound engineer to address the signal to the selected audio path. The odd/even numbered switches are used to send the signal to sub-groups (then you can send their signal to L/R outs) while L/R switch sends the signal directly to Main Mix output. These switches can be used in several ways to better suite your application: Application Live 1 Signals are grouped in a way that the sound engineer can easily control the band sections.
Final links The final links in audio systems are graphical equalisers, loudspeaker processors and finally amplifiers and speakers. Graphical equalisers have the same problems as the Cyclone's EQ. If excessive boost is applied to the signal, the graphic equaliser's output (and subsequent electronics too!) may be overloaded. If, Cyclone output is higher than the maximum input level of the graphic, the input of the graphic equalizer may be overloaded. Loudspeaker processors have similar problems.
GLOSSARY In this owner's manuals we used terms of pro audio slang, here's the explanation of some of those words SWEET SPOT rd It's the best place to listen to your mix, with all the details of stereo front, it's the 3 corner of a triangle, where the two other corners are the speakers. MAKE UP It's totally different from your girlfriend beauty content...it's just the way compressors and limiters work in order not to loose level.
