29. ts female XLR 1 4 TRS Tip Ring Sleeve These balanced inputs are in parallel so do not connect more than one signal at a time to input jacks each channel You can connect either a balanced or an unbalanced signal to 1 4 input jack servo circuit detects when there is an unbalanced signal and automatically adjusts the input level by 6 dB compensate for the lower level See Appendix B Connectors on page 14 for information on output connection wiring 17 SIDE CHAIN This 1 4 TRS connector serves as an insert point to control the compressor When a 1 4 TRS plug is connected to the SIDE CHAIN jack the tip sends out a pre compressor version of the signal which can be passed through a processor like an equalizer or de esser and then returned via the ring of the plug Special Insert Y cords are available for this type of Send Return insert jack It s important to note that the signal at the SIDE CHAIN SEND Tip is not the actual signal passing through compressor but a buffered duplicate of the signal that can be processed externally to tailor the control signal Here are some examples of common ways use the SIDE CHAIN connection Frequency dependent compression Connect the SIDE CHAIN SEND the input of a graphic equalizer and the output of the equalizer to SIDE CHAIN RETURN Boost low frequencies with the graphic equalizer to trigger the compressor off the bass dr
30. um Time shifted compression Split the audio signal prior to the SQe2 and route one signal directly to the SIDE CHAIN RETURN no connection to the SIDE CHAIN SEND Route the other signal through delay processor and then to the SQe2 input By experimenting with the delay time the compressor can anticipate the signal at its input and trigger the compression slightly ahead of the actual peaks Ducking Use a microphone to trigger the compressor and reduce level of the audio signal while an announcement is being made over a PA system Connect the microphone signal to the SIDE CHAIN RETURN no connection to the SIDE CHAIN SEND GENERAL PRECAUTIONS AND CONSIDERATIONS Rack Mounting 502 is designed to be mounted in a standard rack It requires only a single rack space 1U 1 75 It also requires 7 5 depth inside the rack not counting the front knobs or rear connectors When designing your rack put the heavier items at the bottom and the lighter items toward the top secure the front panel of the SQe2 to the front of the rack using four screws with soft washers to prevent scratching the panel Thermal Considerations Avoid mounting the SQe2 directly over devices that produce heat such as power amplifiers As with all electronic components it is best to provide cool air circulation around the SQe2 to avoid overheating The ambient temperature should not exceed 113 F 45 C AC Power Considerations Be sure th
