PLATINUM OCTOPRE LE NEW
OctoPre LE, the "lite edition" of the company's established OctoPre,
brings Focusrite pre-amplification and A/D-D/A conversion to a new
level of affordability for DAW and digital console users. OctoPre LE
provides eight channels of pristine Focusrite preamps, including two
“Super Channels" that offer mic impedance matching and instrument
DI inputs plus other features.
With the optional A/D-D/A board installed, OctoPre LE brings more to
the DAW via ADAT* lightpipe than ever before, allowing users to make
the most of often neglected ADAT* inputs and outputs for tracking and
monitoring. In addition, the A/D-D/A option provides wordclock in and
out as well as being the only converter in its class to feature 256x clock
- a must-have for Pro Tools engineers.
Extremely easy to use, OctoPre LE helps to save session time and
engineer heartache. Auto switching front and rear panel inputs and
total control of the digital I/O from the front fascia allow the unit to
remain racked and patched, with every I/O solution available at the
flick of a switch. In typical Focusrite fashion, the OctoPre LE upholds
professional standards throughout, boasting class-leading specifications.

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.

Dimensions 19“W x 1?“H x 6“D, 482 x 44 x 155mm | Highly versatile and portable, Sound Devices' MM-1 is a single-channel, portable microphone preamplifier with a powerful headphone monitoring function. Proven in mission-critical applications, the high-performance microphone preamplifier uses a transformer-balanced input and output with a bipolar ±15 volt power supply to produce low-noise, low-distortion gain at all switch positions. It features an "unclippable" dual-stage limiter and two-position high-pass filter. Flexible microphone powering provides phantom power at 48 volts or 12 volts and 12-volt T-power. It is powered from two-AA batteries or external 5-18 VDC.
The MM-1 is at home in high-definition television production, corporate/industrial environments, radio/television announce booths, and music production. Its headphone monitor is an advantage in applications where communications channels or mix-minus feeds need to be monitored in headphones. The user can monitor both microphone audio and external audio sources in headphones with level control.
The MM-1 is designed to be durable. Its aluminum chassis, oversized end panels, machined knobs, and panel mounted connectors assure reliable mechanical operation.
- Maximum of 66 dB of gain, in eleven discrete steps
- Dynamic range exceeding 120 dB
- 10 Hz to 50 kHz audio bandwidth
- High immunity to RF interference

- Extended range peak limiter via dual opto-isolators makes preamplifier virtually "unclippable“
- Selectable 48-volt / 12-volt phantom power or 12-volt "T" power
- High-pass filter @ 80 or 160 Hz, 6 dB per octave
- Headphone monitoring of microphone audio, monitor audio, or a mix of both
- Monitor input accepts mono, balanced or unbalanced line-level inputs on 1/4-inch tip-ring-sleeve connector
- Separate level control of Monitor gain and overall headphone gain
- Split ear function via DIP switches
- Internal battery power (two-AA)

EWI PDI-100 PARA ACOUSTIC DI Box
This is a medium grade professional application Para Acoustic Active DI, which will work well on instruments with passive pickups or active pickups.
The construction is reasonably rugged and the components are well suited for the application yielding results that are typically acceptable for all but the most discerning artists.
The on-board tone and volume controls give the operator a lot of choices in shaping their sound prior to sending the signal to the mix console. This allows an artist to use this device in-place of or in addition to a traditional stage amp for their instrument. This is an excellent choice for IEM bands, or bands that like to keep their stage volume low.
This item is typically used to split the instrument signal going to a stage amp so a feed can be sent also to the mix board, or be used as a stand-alone instrument pre-amp. It is equipped with a ¼” jack for input, a 1/4" jack for output to a stage amp, one XLR jack for the send to the board and a TRS jack for inserting an FX device.Since this is an active D.I. box, it needs to be powered which can be done either with Phantom Power from the mix board, or with the supplied internal 9v battery. The battery is fairly easy to change by removing one screw in the bottom of the case.
