O Channel input connectors Each of the EMX3500's input channels is provided with both a balanced XLR connector (A) and a balanced tipring- sleeve 1/4" phone jack (B). The channel's input selector switch on the front panel is used to select between these input connectors. Signal sources that don't require phantom power should be connected to the phone jack (B) when the PHANTOM POWER ON/ OFF switch is turned on.

The channel insertion point is ideal for the insertion of a compressors, noise gate, equalizer, or other effect that needs to be applied to a specific channel only. This jack accommodates both the send (output) and receive (input) lines required by the insert point. The signals are sent and received at a nominal level of +0 dB. TIP-RING-SLEEVE PHONE PLUG Tip : output (send to external device) Sleeve :ground Ring : input (return from external device) (PHANTOM) B A PAD HA Q Q R EFFECT RETURN jacks The output from external effect units fed by the EFFECT SEND jacks can be returned to the main program mix via these 1/4" phone jacks. Note that both effect circuits have stereo EFFECT RETURN jacks, allowing the EMX3500 to accommodate effect devices with stereo output. To return a monophonic effect signal to both channels of the master stereo mixing bus, use the EFFECT RETURN L jack. (The R jack should be left open.) The levels of the signals input by these jacks are adjusted by the corresponding EFFECT RETURN controls on the front panel. The nominal input level for these jacks is +4 dB. S EFFECT SEND jacks These 1/4" phone jacks deliver the corresponding effect mix signals to feed external effect devices. Note that the EFFECT SEND 2 output is active even when the internal digital signal processor is turned on. The levels of the signals output by these jacks are adjusted by the corresponding EFFECT SEND controls on the front panel. The nominal output level for these jacks is +4 dB. T REC OUT and TAPE IN jacks These phono jacks are used to send stereo signals (–10 dBV) to and from a connected tape deck. The REC OUT jacks send the unequalized pre-fader signal from the master bus for recording by the tape deck. The TAPE IN jacks connect the playback signal from the tape deck to the master mixing bus in front of the GEQ. The levels of these signals are adjusted by the REC OUT and TAPE IN controls on the front panel. U LINE INSERT I/O jacks These tip-ring-sleeve 1/4" phone jacks serve as insert patch points for the connection of external signal processing devices or other equipment to the master stereo mixing bus. There are two pairs of jacks, allowing the devices to be connected both in front of and behind the GEQ. The line insertion points are ideal for the insertion of stereo effects that need to be applied to the entire mix. These jacks accommodate both the send (output) and receive (input) lines required by the insert points. The signals are sent and received at a nominal level of +4 dB. V MONITOR OUT jacks These 1/4" phone jacks deliver the signal from the monitor mixing bus to feed external monitor speaker systems driven by external amplifiers. Although both these jacks output the same monitor mix signal, their output levels can be adjusted individually using the corresponding MONITOR output level controls on the front panel. These jacks have a nominal output level of +4 dB. Rear Panel LR SPEAKER 2 LR SPEAKER 1 POWER WX W POWER switch This switch turns the EMX3500’s power supply on and off. The VU meters on the front panel will light when the power is on. X SPEAKER jacks These standard 1/4" phone jacks are the main speaker-level outputs from the EMX3500’s power amplifier. The EMX3500 provides two pairs of stereo speaker output jacks, labeled SPEAKER 1 and SPEAKER 2. The SPEAKER 1 and SPEAKER 2 jacks for each output channel (right and left) are wired in parallel. If you connect a speaker system to only one of the jacks (SPEAKER 1 or SPEAKER 2), the total load impedance of the speaker system may be as low as 4.. If you plug speakers into both the SPEAKER 1 and SPEAKER 2 jacks of either channel, the load impedance of each speaker system must be no less than 8.. OPERATING TIPS Cautions for Connected Sources Please observe the following cautions when connecting sound sources to the EMX3500: • TURN THE POWER OFF FIRST Always make sure that the mixer’s POWER switch is turned off before connecting or disconnecting any cables.
