AEROMIX AMX 123 Operating Manual
The Fitness Audio Aeromix AMX-123 Hook-up Guide Thank you for purchasing the Aeromix AMX-123 Voice-over-Music Mixer by Fitness Audio designed to be easy to operate but with more complex options for the installer to take advantage of when initially setting up the sound system. We suggest that your sound contractor installs this mixer for you to take full advantage of the options that are available. However, if you feel capable of doing it yourself then please follow these simple steps for the basic connection to your Group Fitness Stereo Sound System. 1. Connecting the Wireless Mic Receiver. Connect the line out jack socket of your wireless microphone receiver to the TRS Mic Input (12) socket on the back of the Aeromix using either a standard mono 6.35mm (quarter inch) jack to jack lead which is usually supplied with wireless receivers or, if it is a Fitness Audio wireless system, the supplied balanced cable XLR to TRS Jack Plug. The Balanced Mic XLR Socket (11) will accept the XLR to XLR cable preferred by many installers. Balanced line connections always sound better than unbalanced ones, revealing more body in the voice, and are less susceptible to noise and interference. 1.1 Connecting a second Wireless Mic Receiver If a second wireless receiver has to be connected then use the other Mic input socket - they will both work together using the Voice Volume Control (1) - balance levels with the receiver s volume control that uses an unbalanced jack to jack connection. 2. Connecting the Music Sources - A CD Player If you are still using a CD player then connect the Line Out or Play sockets of your CD Player to the Music 1 Input Sockets (16) on the Aeromix using a 2 RCA to 2 RCA lead. Remember that Red is Right and Left is White (or black). If using a Fitness Audio AeroLink Bluetooth Receiver then also connect it to this input if it s available or (17) if it s not. 2.2 A Personal Portable MP3 Player or Smartphone Connect a Portable MP3 Player Headphone socket to the MP3 In Sockets (17) of the Aeromix using a floating 2 RCA to 3.5mm (⅛ ) minijack. 2.3 Connecting an MP3 Player using the White ijax Cable as supplied. Use the exclusive Fitness Audio ijax 6.35mm stereo jack to 3.5mm stereo mini-jack lead to connect to the headphone/line out socket of your MP3 player to the 6.35mm ALT. 2 IN(6) jack socket on the front panel of the Aeromix. When this lead is plugged into the front socket the signal is diverted from any player plugged into the rear panel MP3 In Sockets(17) until the jack plug is removed. Additional ijax cables are available from your Fitness Audio Dealer if required. 3. Connecting to the Power Amplifier Connect a dual 6.35mm jack lead (balanced or unbalanced) from the LEFT & RIGHT(20) pair of output sockets to your amplifier's input sockets. A pair of 1m TRS Jack to XLR-M cables are supplied in some areas for this purpose. 4. Connecting the Outputs Use the MONO Output (21) to connect to a sub-woofer or it can be used for driving another mixer/amplifier or it could be used to connect to a wireless transmitter, or recording system.

Music Only Monitor (MOM) Output 4.1 Use the MOM (MUSIC ONLY MONITOR)(22) to drive an on-stage foldback monitor for the instructors to hear the beat. We recommend using a powered wedge speaker positioned at the back and centre, firing up from the floor of the stage, of a size and power that will do the job. You could also install a smaller powered speaker on the ceiling about a metre in front of centre stage firing down at the instructors head. Itʼs all about letting the Instructors hear the beat as loud as they want it on stage without the mic giving any feedback problems. 5. Power On With the speakers connected to the power amplifier, connect the 24VDC Power Pack to your power point, turn the Power Switch (8) on and make sure the full system is fully powered up. Thereʼs a cable restraining post to secure the DC plug, so wrap the cable once around to prevent it being accidentally pulled out. 6. Setting the volume levels. Start from the end! Firstly adjust the level controls of your power amplifier - set its volume controls up to maximum. Next set the Master Level (18) on the rear panel to the minimum point using a small screwdriver and the Mic Trim (14) screwpot to about half way. 6.1 Minimum Level Volume Control Youʼll notice that the MUSIC 2 Volume Control (5) doesnʼt have a true off position. This is intentional. Set your MP3 Player to the loudest output setting and plug the white ijax cable into the headphone socket and the other end into the mixer socket (6). Make sure the Music 2 Volume Control is set at minimum. Now start a typical loud track playing from the player and adjust the Master upwards to establish a minimum loudness level for talk-over purposes. Now you can increase the loudness from there up to high energy class levels the same as you would get from a CD. 6.2 Setting the microphone level. Check that the receiver's mic/line output selector (if there is one) is set to MIC. If you're using receiver with a variable output volume control then turn the it to the midway or 12 o'clock position. Next turn the Voice (1) control on the Aeromix up to the 2 o'clock position. Put the
microphone on, turn on the transmitter and start counting out loud while moving the Mic Trim(14) control on the back until feedback (mic howling) starts. Edge it back a touch until the voice sounds dry with no hint of ringing or feedback. If you need more gain then advance the receiverʼs volume control until itʼs loud enough. Fine tune by walking around the room talking and seeing how close you can get to the speakers without the mic feeding back - the better they are the closer you'll get. This process is called setting the maximum gain-beforefeedback position. Set the MIC FILTER (15) to ON if youʼre using large speaker boxers or a system with sub-woofers. Leave off if using smaller speakers - always compare on v off. Please note - if you do need to EQ the Voice Channel or process it through a DSP device then use the MIC INSERT (13) socket on the rear. Youʼll need an adaptor cable of a 6.35mm TRS plug to 2 x 6.35mm L & R in-line plugs or sockets - one will take the voice from the mixer and the other will feed it back into the input after processing. 6.3 Itʼs a Voice-Over-Music Mixer! Now play some music and adjust the music volume against the mic level while projecting your voice as you would if teaching a Group Fitness or Dance Class. Remember, it's a Voice over Music Sound System - the audience wants to hear what's being said above the level of the music. At the end of the class the instructor can return the Volume Control to the start level to keep the vibe going when doing the cool down and for background music at any time. 6.4 Using the PUNCH button (4) The punch button is a pre-set bass & treble booster circuit to give your MP3 files a bit more sonic punch. It sounds best when your playerʼs eq is set to flat. Warning: Do not use when the volume is turned up really high as this could result in damage to some amps and/or speakers. 6.5 Setting the Tone Controls. If using a CD Player, start by playing a test music track. Set the Music 1 Volume (2) to a medium level and adjust the Bass And Treble Controls (3) by sweeping each one from left to right and back again. Decide on a setting that gives a more subtle fullness to the music rather than an exaggerated bass and/or treble. Note that these are removable knobs and can be replaced by the two black blanking rubber plugs suppled for a set and forget arrangement if required by management. 7. USB Power Sockets Two USB Charging Ports are provided on the AMX-123, use the Rear Panel USB (10) to connect a fixed floating charging cable like the ones supplied with an Apple 30 pin dock connector and use the Front Panel USB (7) for charging all other types of Smartphones and MP3 Players. Please note these are only charging sockets and cannot be used to play back music from any MP3 player or USB Drive. 8. Music Mute Relay Circuit Many responsible Building Approval Authorities around the world require a cut-out switch on any powerful music system installed in a private, public or community centre (ie city or council owned fitness centres). The circuit is closed by the fire alarm control system if an alarm is activated anywhere in the building. This is good practice and we expect that this will eventually be a compliance standard for all installations everywhere. We have opted to use a music cut-out circuit rather than a total power cut system, as we feel that the mic user should be trained to respond to the fire alarm and lead their people out to
safety using the vocal power of their mic through the sound system. This connection should only be installed by a licensed contractor. To use the circuit a two-wire cable has to be run from the General Services Board connected to the building's alarm system and the two wires are connected to the screw terminals on the board. Get some music playing and have someone on the mic just talking, you can check itʼs working by shorting a test cable screwed into the green Molex Connector (19). Use the right hand side of the connector, the earth cable goes on the inside contact #3 and the active cable to the outside of the pair #4 marked 1 above, the music should cut out, leaving the mic working. Once tested, connect the alarm board cable to the Molex connector. The other pair of contacts on the left arenʼt used. Fitness Audio products are distributed worldwide by Fitness Audio Network.
