5、ing and recording console with unparalleled performance/features intrinsic with intuitive layout and operation. The vision required the analogue sound path to be controlled in the digital domain via a high degree of signal routing and moving fader automation enabling the live sound engineer whether

6、in a touring or theatre production environment to utilise automation functions in order to enhance mix efficiency and performance to performance consistency. The benchmark for the XL4 was the XL3 console which during production since 1990 gained a worldwide reputation for unequaled sonic performance

7、 and system transparency culminating in its award for best live sound mixing console 1993 and 1994. Bob Doyle, Midas Sales & Marketing Director, spent ten months finalising the XL4 specification, discussing its concept with world class sound engineers and rental company heads as well as theatrical p

8、roduction designers and artists alike. The criteria was to develop a mixing environment which enhanced the creativity of the mixing engineer by automating the repetitive functions of specific mix and cue requirements, thus leaving he or she free to concentrate on the main thrust of live mixing by re

9、producing the Artists music as it should be. In our opinion, the XL4 combines all these criteria in a coherent, easy to operate mixing aid with unsurpassed sound and sonic quality.

Output meters. 28 peak reading meters (each covering a 60dB range in 3dB steps) are used to monitor all the main outputs i.e. 16 groups, 8 matrix, 2 masters and

23、2 local outputs. They and can be switched globally to monitor pre fader or post fader signals and can also be used to monitor the 24 aux outputs. 10 input VCA faders. 10 motorised VCA master faders control the channel and aux inputs whilst a further 2 VCA grand master faders control the audio groups

24、. Each VCA master has a solo switch which gives the engineer an opportunity to monitor the signals within the VCA subgroup. Also incorporated is a VCA mute which act on post fader signals only and effectively adds a further 12 automute scenes to the existing dedicated automutes. Matrix. As standard

25、the 8 matrix outputs derive their signals from the 16 audio groups, left and right masters creating a 18 X 8 matrix. The module also houses the stereo aux masters which have their own outputs at all times but which can be routed directly into the matrix giving an additional 48 X 8 matrix sourcing di

Apart from assignment the operation of these mutes is entirely independent of the automation system. Automation. The automation system can store an

The 12 motorised VCA master faders give dynamic control of signal levels within the console and all automation information can be exported or imported in a variety of different medium
