When tasting wine, it is important that a comparison is as neutral as possible. The same applies to selecting loudspeakers.To accurately judge sound characteristics, it is essential to listen to different loudspeakers under the same conditions.
Comfortable loudspeaker routing with variable level control for an uncompromising comparison on the sales floor, along with multi-monitor and multi-room applications, are just some of the ways the GrandAudition MK2 can be effectively put to use.
GrandAudition MK2 lets you connect 16 individual loudspeakers or eight loudspeaker pairs and up to eight subwoofers - all with balanced line-level XLR connectors and housed in two 19\" rack units. Depending on how you want to use GrandAudition MK2, the outputs can be selected either individually or as stereo pairs via an intuitive browser-based app or from the unit itself.
Thereby you can choose to just switch between loudspeakers or freely configure any output combination you want, making it not only the ideal solution for a loudspeaker presentation, but also an excellent choice as a central-control-unit for trade fairs, in laboratories and for multi-room sound distribution.
Source material is supplied from a mixer, CD player or digital audio workstation through two balanced XLR inputs - with volume control, of course. But that\'s not all. GrandAudition MK2 is also equipped with a built-in USB media player on which reference titles can be accessed in WAV, AIF, FLAC, MP3 and OGG data formats.
Highlight of GrandAudition MK2
The browser-based remote can be controlled on a tablet or laptop, offering maximum operating convenience. Ethernet and WLAN-capable devices can be used for complete configuration and control of the unit, including channel naming, media player, and other practical functions.
The ability to individually adjust the level for each output and its quick and noiseless switching mechanism, makes it possible to accurately compare loudspeakers and help you reliably guide your customers to select the right loudspeaker. Routing applications that use different levels for each output can also be set up, and a fully analogue signal path with the highest quality is also of course guaranteed with Palmer.
If necessary, you can cascade units to triple the impressive number of 16 channels plus 8 outputs and thus manage even the largest routing scenarios for monitors, such as in presentation areas. You can also use the subwoofer outputs to connect additional loudspeakers without experiencing any technical drawbacks.
In addition to powered loudspeakers, passive loudspeakers can be incorporated with power amps. Signals can also be distributed over multiple line outputs for other applications, for example, by connecting as many as 24 headphone amplifiers to one source signal - an invaluable aid in conference technology and at trade fairs. And to top it all off, GrandAudition MK2 performs remarkably well in measuring laboratories.
In short, GrandAudition MK2, with its clearly arranged features and ease of use, offers comfortable loudspeaker routing with professional sound neutrality.

| Overview
More sound to your amps and speakers
The secret to making speakers sound great lies with the crossover you use. With the dbx® 223xs Crossover you\'ll get great performance, ultra low-noise, rugged reliability and four decades of dbx knowledge and expertise in building the world\'s finest processors. The 223xs uses precision filters to separate the audio signal and direct the correct frequencies to your loudspeaker drivers. By directing only the specific frequency bands to each speaker driver the 223xs leaves your amplifiers free to use their full power on the usable signal eliminating distortion and giving your PA system a cleaner and better sound.
The dbx 223xs is a dual channel crossover with all the features you would expect from a professional product. It features Linkwitz-Riley 24dB per octave filters, independent output gain controls for level matching, output phase inversion, 40 Hz low cut filter, and optional mono summing of the low frequency (subwoofer) output. Everything in the design exudes great precision from the solid "click" controls to the high quality XLR inputs and outputs

Flawless performance in any audio environment
Today?s venues face a growing need to provide a multiplicity of audio feeds
from presentations, conferences, orchestral performances and lectures. The
advent of digital broadcasting, the growth of webcasts and direct-to-CD
archiving highlight the deficiencies in audio splitting systems more than ever
before. Whether the final product is a broadcast feed or CD sales of an unrepeatable
lecture, performance or event, end-users? expectations of audio quality are
higher than ever.With these requirements in mind, ARX has developed the
MSX 8 Active Microphone/Line Splitter to deliver the performance required by
today?s standards of audio production. Active microphone and line splitting has
a number of benefits over passive splitters: primarily these are improved sound
quality, noise figures comparable to the best microphone inputs, and increased
resistance to RFI. All of which translate into superb audio quality for your clients.
About the MSX 8
The MSX 8 consists of two channels of actively buffered ultra low noise Microphone/
Line Splitter. Each of these channels has four electronically Balanced splits ? two
on the rear panel, plus two more on the front panel. All four output splits have the
option of transformer balancing if so specified.Each channel has a ?20 dB pad switch
plus silently switchable 48V Phantom power with indicator LED.Gain through the MSX 8
can be set individually by the small DIP switches on the rear of each channel, from 0dB
through to +40 dB in 10 dB stepsA ?Link? switch links Channel 1 to Channel 2, providing
an ultimate maximum of 8 Outputs from a single input. An indicator LED shows when this
is active. A Clip LED indicates imminent signal overload through the channel, and a
numbered marker panel on the front provides a space where individual channel connections
can be noted.For remote or mobile applications a 5 pin DIN connector on the rear panel
provides an access point to connect a 12V DC power supply
Inside Information
Internally, powerful RF input filtering removes both common mode and differential interference
at ultrasonic frequencies and above. High CMRR is achieved by the use of precision components
throughout.Advanced user options include internally jumper linking Inputs to Main outputs, and
Ground lifting Output Pins 1as required.
Internal Power Supply
The MSX 8 has a low noise transformer based power supply to obtain the maximum benefit from
the ultra low noise design of the splitter circuitry.
Summing up, the feature packed MSX 8 is the answer wherever transparent signal buffering and
routing is required.
