1. 3 The third option AES EBU In L R Rev functions identically to the second option except that the left and right channels are swapped Therefore in this mode the left channel of the AES EBU In is routed to OUT4 and the right channel of the AES EBU In is routed to OUTS 4 Options four and five connect the hardware analog inputs 1 amp 2 or 3 amp 4 respectively directly to the VX442 s hardware analog outputs 3 amp 4 For example when H W In 1 2 is selected any signal present at the IN1 port is copied to OUT3 and any signal present at the IN2 port is copied to OUT4 This same behavior applies to H W In 3 4 when selected The rightmost vertical column of Patchbay Router page H W Out AES EBU connects the VX442 s hardware AES EBU output to one of six stereo sources 1 The default setting WavOut AES EBU connects the AES EBU Out port to your music software or Windows multimedia applet In other words when music software plays audio to the device named WavOut AES EBU VX442 it will be routed directly to the hardware AES EBU output on your VX442 2 The second option Monitor Mixer connects the AES EBU Out port to the outputs of the VX442 monitor mixer For more information on the capabilities of the monitor mixer please see the section Monitor Mixer Page 3 The third option AES EBU In connects the AES EBU Out port directly to the hardware AES EBU input on the VX442. Peak Meters Each peak meter indicates an audio signal level in dB relative to full scale This means that a full scale signal is referred to as 0 dB and a signal that is 12 dB quieter than full scale is referred to as 12 dB The meters are vertically color coded into three sections green yellow and red The green section represents a safe zone ranging from approximately 48 dB to 12 dB Most audio signals should appropriately fill this section of the meter The yellow section ranges from 12 dB to 3 dB as the signal approaches a hotter evel For best capture resolution it is recommended to adjust the output gain of the source or the input gain of the board so as to visualize the level in this area The red section of the meter ranges from 3 dB to 0 dB On the input evel meters a O dB condition indicates overload and audio clipping may occur Therefore make sure to adjust the incoming audio levels so that they do not peak in the red section too long On all output level meters 0 dB indicates ull scale output Unlike the inputs hardware clipping is impossible on the outputs because of the 36 bit resolution built into the mixer hardware However note that it is possible to mix multiple tracks within your software application and cause clipping to occur in the output stream before it reaches he VX442 output hardware or monitor mixer Master Volume At the left side of the Monitor Mixer page you will see

5. the Master Volume faders and peak meters These faders have the longest throw and highest meter resolution of any level controls in the mixer page They control the VK442 Manuel utilisateur overall stereo level of the mixer output The peak meters indicate the output signal levels with respect to full scale and are directly affected by the settings of the master volume faders Mixer Inputs These inputs accept hardware audio streams directly from the VX442 s analog and digital input ports and software audio streams digital audio generated by software to be output This combination of streams makes the monitor mixer extremely flexible Each mixer input channel has its own level fader and may be panned anywhere in the left right stereo field Each input also has its own peak meter The peak meters indicate the incoming pre fader levels of the incoming audio and are therefore not affected by the fader settings However the input faders do affect the levels of the signals exiting the mixer and you will see the effect of the input faders on the output Master Volume peak meters By reason of the large number of mixer inputs not all inputs are displayed simultaneously Use the scroll bar at the bottom of the VX442 Control Panel to scroll the view left or right From far left to right the inputs are labeled WavOut 1 2 WavOut 3 4 then WavOut AES EBU These inputs accept the digital
