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.

The PRE-73 Mk2 pre-amp and the FC3 condenser microphone in one bundle. The bundle also includes Golden Age P1 Pop Filter, Proel RSM180 mic stand and Proel CHL250 5m cable. | 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.

| Vacuum Tube Mic Preamp. 12AX7 Vacuum Tube. +48V Phantom Power, 20dB Pad.
This premium tube mic/line preamp features an integrated limiter for studio,
live and hard disk recording applications. It features a carefully-selected
12AX7 vacuum tube with Behringer's UTC technology for exceptional warmth
and lowest noise. Using the MIC100 is a great way to eliminate the "dull"
sound of standard digital recorders & sound cards. Also, it perfectly
complements studio-grade condenser mics. When used as a high-end DI-box,
it ensures outstanding signal integrity. Features also include a phase reverse
switch, +48 V phantom power, a 20 dB pad, and balanced I/O.
The heart of the Tube Untragain is an extremely low-noise microphone preamp
circuitry that uses discrete components and produces a highly trans-parent
sound. In combination with Behringer's tube technology, the operational amplifiers
4580 and a sophisticated circuit topology, the Tube Untragain yields excellent
noise and distortion properties. The innovative UTC circuitry that has been developed
by our engineering team offers an abundance of sound-shaping possibilities.
Absolute musicality was Behringer's major goal when we designed the Tube
Untragain. The result is a device that, thanks to our tube circuitry, lends an
incredible punch to percussion instruments. On the other hand, instruments
that are rich in upper harmonics will receive more transparency. The sound
will be warm, detailed and brilliant.

The PRE-73 MKIII is a one-channel vintage style microphone-, line- and instrument preamplifier. The signal path uses only discrete components like resistors, capacitors and transistors. The in- and output is transformer balanced, using two different transformers, each one optimized for its purpose. This is the way audio components were built before integrated circuits became available.
The circuit used in the PRE-73 MKIII is similar to the preamp section in the classical 1073 module with a corresponding sound character that is warm, punchy, sweet and musical. These classic characteristics have 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 essence of this sound is now available at a surprisingly low cost, making it available to nearly everyone.
Features :
-
Vintage Style electronics. No intergrated circuits in the signal path.
-
