YAMAHA REV-100 DIGITAL MULTI-EFFECT PROCESSOR

The DPR-504 is a 4-channel noise gate.

Each channel features:
A parametric key filter with key filter listening.
Simultaneous key level and threshold metering with average and
peak metering.
A gate status LED.
A RELEASE/HOLD control (hold tracks proportionally with release
times).
Attack switchable auto/fast (auto tracks signal dynamics for optimum
setting).
Link (links two channels together).
Key source allows external triggers.

The Range switch selects between 7OdB and 2OdB gating depth to
provide alternative release profiles.
The unit features electronically balanced inputs and outputs. 

• Error proof operation to smooth uneven levels, add sustain to guitars, fatten drums or tighten up mixes
• New gate timing algorithms ensure the smoothest release characteristics
• Program-adaptive expander/gates
• Great sounding dynamics control for any type of program material
• Separate precision LED displays for gain reduction, compression threshold and gate threshold allow quick, accurate setup
• Stereo or dual-mono operation
• Balanced inputs and outputs on 1/4" TRS and XLR connectors
• Side Chain insert
• Classic dbx® "Auto" mode

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
