Operating Manual -MX-406 Stereo Microphone/Line Mixer 4. FRONT PANEL CONTROLS 4.1 Input Gain This three position switch sets the operating level of the microphone and line input preamp. The corresponding switch values -20db, -40dB, and -60dB refer not to the actual gain, but rather to the expected nominal input signal strength. Best signal to noise ratio is obtained with higher gain settings.
Operating Manual - MX-406 Stereo Microphone/Line Mixer capacity of the MX-406, the stereo line input can be used as stacking inputs for supplementing the MX-406 with another mixer, such as an Ashly LX-308 stereo line level mixer. 4.7 Aux Master Output This control adjust the level of the aux master ¼" jack output, which gets it's signal from the six aux level controls on the input channels. It is used for an effects unit send, or can drive a power amplifier for monitors or an extra loudspeaker zone. 4.
Operating Manual -MX-406 Stereo Microphone/Line Mixer 5. CONNECTORS AND CABLES The MX-406 mixer is fitted with five types of audio connectors: 3-pin XLR type male (mono output), 3-pin XLR type female (mic inputs), 1/4" tip-ring-sleeve (TRS) phone jack, 3.5mm jack (stereo line in), and RCA jack. Certain 1/4" jack connections may use an unbalanced mono plug, which is also shown. Two-conductor (twisted pair) shielded cable is best for all XLR type connections. Belden No.
Operating Manual - MX-406 Stereo Microphone/Line Mixer 6.2 Input Pad 6.5 Stereo Line Input The input pad is a 20dB attenuation switch on the rear panel for use with the XLR microphone inputs. It should normally be left in the "out" position for best signal to noise ratio and should only be used when the input is being overdriven with the gain control at its minimum setting. The stereo line RCA inputs, and the front panel stereo line in 3.
Operating Manual -MX-406 Stereo Microphone/Line Mixer (Mono Output, cont.) Note: The mono transformer-balanced output is designed to drive up to +24dBu into 600 ohm loads. Because of the nature of an output transformer, the output level increases as the impedance of the terminating load becomes higher than 600 ohms.
Operating Manual - MX-406 Stereo Microphone/Line Mixer 7.2 Meeting Room, Board Room, or Church Mixer Using Remote Control: In this illustration, the MX-406 is interfaced with an Ashly VCM-88 eight channel remote level controller, allowing the mixer to be operated from a distance by a non-technical person. Remote control of the VCM-88 is achieved through the use of Ashly's RD-8 desk-top remote controller, RW-8 wall-plate version, or PC control using Protea System Software.
Operating Manual -MX-406 Stereo Microphone/Line Mixer 8.3 Excessive Noise If the noise is in the form of hiss, the problem is usually due to an input stage set for insufficient gain and then compensating for it by increasing the level. Try increasing gain and reducing level. Also, check that the -20dB rear panel pad switch is not unnecessarily enabled. 8.4 Excessive hum This is usually caused by "ground loops" in the system wiring.
