| Content | The dbx® 286s is a full featured Channel Strip Processor that delivers a studio quality microphone/instrument preamplifier and four processors that can be used independently or in any combination. Why mic up vocals and instruments through a noisy, blurry mixer? The sonically pristine dbx 286s Mic Preamp has all the features you need, including wide-ranging input gain control, switchable +48V phantom power, and an 80Hz high-pass filter to remove low frequency hum, rumble or wind. Use the patented dbx OverEasy® compressor to transparently smooth out uneven acoustic tracks or deliver that classic "in your face" vocal performance that only a dbx compressor can. Eliminate vocal sibilance and high frequency distortion from instruments such as cymbals with the frequency tunable De-Esser. Fine-tune the Enhancer HF Detail control to add sparkle and crispness to your tracks and make adjustments to the LF Detail control to add fullness and depth to vocals and bass instruments while cleaning up the muddy low midrange frequencies. And, the separate threshold and ratio controls on the Expander/Gate allow you to subtly reduce headphone leakage or radically gate noisy guitar amps.
The dbx 286s offers a full compliment of metering and status LEDs to visually guide you to achieving the right sound. The floating balanced XLR Mic Input accepts balanced or unbalanced inputs to easily connect to professional and home studio microphones. The additional 1/4" TRS Line Input can accept balanced/unbalanced signals to process live electronic instruments or pre-recorded tracks at mixdown. Use the Insert jack to interface between the Mic Preamp and the signal processing sections to "loop out" to external processors (such as EQ or delay unit) or to mix the Mic Preamp's signal out to an external destination.
The cost and hassle of patching together multiple processors for use on one track can be frustrating. The dbx 286s provides you with all the mic processing you need in one box, with the shortest, cleanest signal path to keep your music sounding its best!

The PreSonus HP60 is the most flexible and advanced headphone amplifier system available for professional and project recording studios as well as live sound in-ear monitoring systems. Loaded with six independent,
loud and clear headphone amplifiers, the HP60 features dual stereo inputs as well as external input, for each
channel allowing you to mix between three stereo audio streams (mix A, mix B, and external input). Stereo output is also available on each channel to send line level headphone channel mixes to additional headphone amplifiers or monitor systems. Each channel features headphone level, mix control between A and B inputs, external input volume, mute and mono. The HP60 also features talkback via external XLR microphone input. Common set up of the HP60 in a recording session is to send the main control room mix to input A. Send the click track to input B. Send the each band member direct recording input to each channelʼs external input (more me). This will allow each band member to create a mix between the main mix, the click track and themselves. The HP60 is the ultimate headphone amplification system delivering loud and clear headphone mixes for real-world recording situations.
Features:
-Six independent ultra low noise, high output headphone amplifiers (150 mW per channel)
-Two sets of stereo inputs (A and B) with balanced TRS connectors
-Stereo external input point on each channel for "more me” with trim control
-Mix control between inputs A and B
-Talkback with external XLR microphone with control
-Direct stereo line output on each channel

Applications
Console input extending for both Digital and Analog mixing
consoles in Studio, Live and Broadcast
Mic Pre-amps for ADAT/ Hard Disk/ Multitrack Recording
Innovation
If you love your compact Digital (or Analog) mixing console, but wish it had
more microphone inputs, ARX has the solution ? the 8 Pre: eight channels
of superb sounding Microphone Pre-amps in a compact 1 RU chassis.
The 8 Pre is the ideal console extender for those times when you need more
microphone inputs. Now you can put those unused line inputs to good use,
and who knows - the 8 Pre pre-amps sound so good that you?ll probably end
up using them all the time instead of the ones that came with your mixer!
Superb Audio Quality
The 8 Pre?s ultra low noise figures come from extensive use of premium
components plus care and attention to board design and layout. The result is
superb, transparent audio quality and the headroom to handle anything that a
mic can throw at it.
Gain is adjustable from 20 db through to 60 dB via a trim control on the front
panel, plus we?ve included a ?20dB Pad switch to tame the hottest condenser
mic output if required. The Clip status LED lights up 1 dB before the onset of
clipping, just to warn you you?re getting close.Phantom power is switchable in
banks of four channels: 1 through 4, 5 through 8. A Phase reverse switch is also
provided on each pre-amp channel to eliminate any close miking problems.
In short, the ARX 8 Pre is the mic Pre-amp that you?ll wish the console manufacturer
had used. It provides a unique solution to today?s multiple Mic Pre-amp requirements.

The PRE-73 Mk2 is the first one-channel low-cost preamp on the market that is using a fully discrete signal path with three separate transformers for the balanced mic input, the line input and the output.
The circuit is very similar to the classical preamp section of the Neve 1073 pre/eq module with a corresponding sound character that is warm, punchy, sweet and musical.
This classical sound has been heard on countless recordings through the years and it is a versatile sound that works very well on most sound sources and in most genres.
The PRE-73 Mk2 has a maximum gain of 80 dB on the mic input and the gain range on the Line input is -20 to + 10 dB. There is also a high-impedance instrument input.
The PRE-73 Mk2 is perfect for almost any signal source, no matter if it's a microphone with a high or low sensitivity (like a passive ribbon mic), a syntheziser or sound module or an electric guitar or bass.
The input impedance of the microphone input can be switched between 300 and 1200 ohms, which makes it possible to affect the tone of most microphones. There is also phase switch and an simple 4-step LED signal level meter.
The output level control makes it possible to make fine gain adjustments and also to overload the main gain stage for more character and then lower the signal to a suitable level before the output stage.
The Mk2 update consists of:
- An unbalanced insert jack (nominal level about 18 dBu) added on the back panel for inserting units like the coming GAP EQ-73, a three band eq.
- LED meter levels adjusted.
- 600 Ohm termination resistor and jumper added to power supply board (accessible from the inside of the unit).
- Revised Gain switch, turning the know clockwise now increase the gain.
- Reduced noise at high gains by a change to the power supply grounding scheme. | • Road proof housing
• High quality components
• Professional balanced XLR outputs
• Level control
The ASC-202 converts consumer level stereo RCA signals to balanced XLR professional line level, and back. One side of the unit, has two XLR inputs and stereo RCA outputs. The other side has stereo RCA inputs and two XLR outputs. Each side has stereo level controls. A possible application of the SC-13 is to use it as a level control in balanced audio lines.
