WORK WD 421 Audio Splitter 2 in & 2 out

Signal distributor. 1 stereo input / 4 stereo outputs or 1 mono input / 8 mono outputs

This audio distributor is very useful to supply several audio devices with only one audio source. Its 2 operating modes allow to work with mono or stereo signals. Output level can be controlled independently.

WD 421 adapts itself to work with different impedances, ensuring that output signal level is at least equal to input signal level. It avoids any undesired attenuation and features a LED vumeter to visualize the input signal level.

1215 Dual 15-Band Graphic Equalizer

The dbx 12 Series were designed to meet the needs of the most
demanding sound reinforcement environments, while offering the
simplicity of straightforward controls. The 1215 provides standard
features like dual channels, 15 2/3 octave bands, ISO frequency
centers, +/-12 dB input gain range, and switchable 40Hz/18 dB per
octave low-cut filters, but also includes other thoughtful features.
These include 45 mm faders; selectable +/-6dB or +/-15dB boost/cut
range for precise gain adjustments; XLR, barrier strip, and 1/4'' TRS
connectors for installation ease; balanced inputs and outputs for quiet
operation; and chassis/signal ground lift capabilities for quick hum isolation.
The visionary design of the dbx 12 Series makes your job easier.

The dbx 12 Series Equalizers were precision engineered to provide years
of maintenance-free operation in any application. The magnetically isolated
transformer, electronically balanced/unbalanced inputs and servo balanced/
unbalanced outputs, RF-filtered inputs and outputs, and power-off hard-wire
relay bypass with 2 second power up delay were steps our engineers took
to ensure compatibility for all installations. Only the best components were
utilized, yielding a 10Hz to 50kHz frequency response, greater than 90dB SNR
(ref +4dBu), less than 0.005% THD +Noise (1kHz at +4dBu), and interchannel
crosstalk of less than -80dB from 20Hz to 20kHz. All this attention to detail
is contained in a 2U steel/aluminum chassis.

Palmer GA MKII Grand Audition MKII

• 24 switchable balanced line outputs
• Intuitive browser-based control software
• Individual level control on each output
• Mono and stereo modes
• Multiple channel selection
• High-quality analogue signal path
• Instant channel switching with no noise or interference
• XLR line inputs and built-in USB media player
• Up to three devices cascadable

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.

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.

About the DI6s
It's a fact of audio life that a lot of equipment that has to be connected to
professional audio systems isn't impedance or level compatible.
Interfaces Unlimited
Tape/cassette/DVD/CD decks, audio for video, drum machines, synthesizers,
bass guitars, computers; at some stage all these need linking up to Balanced
inputs, whether the application is Live sound, Studio or Broadcast.
To solve these problems, we've developed the DI-6s:

Six active D.I. (Direct Injection) boxes,
plus a 6 into 1 Line Mixer,
plus a 1 to 6 Splitter,
All of this in a compact, all steel 1 RU package.

A Pro Audio Toolbox
This unique and flexible audio toolbox allows Six independent unbalanced
audio sources to easily and quietly interface with Balanced pro audio systems,
either to individual channels or summed down to one Master output.
But that's not all. By pressing a single switch on the rear panel the DI6s will
change from being Direct Boxes and a Mixer to being a 6 way Splitter (line
distribution amplifier). Now it will split an incoming signal to 6 individual outputs
or zones.
On the front panel, each channel has 2 IN/OUT jacks, a level control from infinity
(off) through 0dB to +15dB gain, and a Clip indicator LED.The Master section has
a Master volume control and status LEDs indicating whether the unit is in DI or
Splitter mode. In addition, as on all ARX single rack unit equipment, each channel
has a numbered marker panel ('scribble strip') you can write on for easy confirmation
of channel assigns.
Balanced Outputs
On the rear, each channel has an XLR Balanced output, with associated Ground lift
switch and status LED, to isolate the chassis and electronic grounds.
The Master section has both Balanced XLR and Unbalanced Jack outputs. In addition
there is a Balanced XLR input with a switch to put the unit in either DI or Splitter mode.
Universal AC Power
AC power range is a universal 100 to 120V or 220 to 240V AC, and is connected to the
unit via a removable power lead and standard 3 pin IEC connector, with built-in fuse and
voltage change switch.
With so many handy functions, plus a true 'user friendly' layout, it's no wonder people call
the DI-6s 'A total Audio Patching System in 1 RU!'
You'll never compromise on Quality when you choose ARX
