เครื่องผสมสัญญาณเสียงแบบดิจิตอล MIDAS PRO1 IP Digital Mixer
เครื่องผสมสัญญาณเสียงแบบดิจิตอล Midas Pro1 IP สำหรับงานติดตั้ง (Install Package) Live Digital Console with 48 Input Channels, 24 MIDAS Microphone Preamplifiers, 27 Mix Buses and 96 kHz Sample Rate
The PRO1 Live Audio System from Midas features a lightweight aluminum frame and field-replaceable power supply for Midas digital consoles. The PRO1 standalone console is easy to configure and operate. Engineers who are new to Midas digital consoles can relax, enjoy the PRO1’s sample-synchronous audio quality, and mix from well within their comfort zone. Engineers already familiar with Midas can just load their existing show file straight into the PRO1, regardless of which Midas digital console it was created on, and carry on working.
This standalone mixing system has 24 mic inputs on the rear of the frame. The 3 AES50 ports can be used to increase the mic input count up to 96 by connecting additional hardware. In addition to the PRO1’s 40 primary input channels, it also features 8 AUX returns, all of which feature 4-band Midas parametric EQ and insert points. These 8 AUX returns can be used as returns for the PRO1’s internal FX processors, or as additional mic channels if sufficient mic inputs are available on the I/O hardware.
A total of 48 input channels have free routing to 27 phase-coherent mix buses, which comprise 16 user-configurable buses (mixes, subgroups, or mix minus groups), and 8 matrix buses. The matrix buses source from inputs, as well as groups, and so can be used as 8 additional AUX mixes (monitor mix and FX sends) that provides a total of 24 mixes (plus L, R & Mono) for monitor mixing duties. All buses can be linked as stereo pairs (except the mono bus). As with all Midas digital consoles, the audio paths can be routed to multiple destinations and the console format can be reconfigured live on a scene-by-scene basis.
The high-resolution screen remains visible even in direct sunlight. The screen provides visual feedback for the entire system. Pressing the HOME key (just to the left of the assignable controls) instantly displays the console overview screen, which keeps all vital information (all metering, all fader positions, mutes, and solos) in view at all times.
This live audio system has up to 100 inputs and 102 outputs, with point-to-point routing anywhere within the network, which can then be patched and routed on a scene-by-scene basis via a powerful snapshot automation system. The PRO 1 system incorporates several special features to aid real-world integration with other important sub-systems.
- Overview
-
- Full-color 15″ daylight-viewable display screen with DVI out
- 8 VCA (Variable Control Association) groups
- 6 POPulation groups
- 96 kHz 40-bit floating-point processing throughout
- Field-replaceable power supply
- Mic Pre Amps
-
- Unique Midas sound
- Based on Midas’ analog mic preamps—XL4, XL3, and Heritage Series
- Both analog and digital gains
- VCA and POPulation
-
- VCA and POPulation groups both have assignable color coding and digital write-on buttons
- VCA Groups allow access to all the channel faders belonging to any of the VCA groups at the press of a switch
- POP (POPulation) groups can contain any combination of channels that you want to access instantly at the press of a switch
- VCA and POP Groups encourage the development of a mental picture, or Mind Map, of the whole system
- Selecting a VCA or POP group will bring all of the members of that group to you, rather than you having to go looking for them
- Input channels can be viewed either by scrolling the input faders or by pressing the EXTEND button, which will populate the VCA faders with additional members of that POP group
- Equalization
-
- Fully interpolated controls
- 4-band parametric EQ
- 4 different filter types
- Dynamics Processing
-
- XL8 dynamics processing
- 4 different input compressor algorithms
- 5 different output compressor algorithms
- A wide choice of dynamics processing
- FX
-
- 40-bit floating-point audio processing
- Custom-designed FX processors
- Internal FX processors operate within Midas’ automatic latency compensation
- Automation
-
- 1,000 snapshot scenes
- Scene-specific routing
- Scene store and recall can be scoped
- MIDI inputs and outputs provided
- Software versions forward and backward compatible
- Show files compatible with any Midas digital console
- Patching
-
- 100 inputs x 102 outputs (maximum capacity), point-to-point routing anywhere within the network
- 24 mic / line inputs with mic preamps
- Up to 48 simultaneous-input processing channels
- 24 analog outputs (including 2 stereo local monitor outputs)
- 3 AES3 outputs
- 2 AES3 inputs
- 27 sample-synchronous, phase-coherent mix buses
- PRO1 is built around a road rugged lightweight aluminum frame
