PLATINUM OCTOPRE
Providing eight pristine discrete channels of Focusrite Class A mic pre and compression,
OctoPre routes directly to any digital audio workstation via eight standard analogue outputs,
or via a choice of two optional 24-bit, 96kHz A/D converters (see below for details). The new
OctoPre offers the unique qualities associated with the Focusrite name at an affordable price.
Each channel features a revolutionary compressor/limiter circuit, providing a warm-sounding
compressor, which morphs into a brick wall limiter to avoid those critical overs, ensuring total
control over all eight channels.
The mic pres featured in OctoPre are the same as those featured elsewhere in the award
winning Focusrite Platinum range. They are a transistor-based Class A design utilising the
same full-bandwidth philosophy as the legendary Red and ISA mic pres, ensuring detail and
clarity without colouration. The first two 'super channels' also feature phase reverse, as well
as TRS jack inputs on the front fascia for quick and easy, DI-free instrument plug-in.
Eight line level balanced (+4 dBu) analogue inputs and outputs are provided as standard via
25-pin D-type connectors. These D-type connectors may be routed to 8 XLRs by means of
an 8-way 25-pin D-type to 8 XLR breakout cable, available separately. In addition to the analogue
outputs, the OctoPre can be fitted with one of the following two digital output options:
24-bit/96 kHz ADAT? interface card
This card provides digital outputs for all eight OctoPre channels, which operate over the full
sample frequency range (44.1, 48, 88.2 and 96 kHz) and can be dithered to 16-, 20-, or 24-bit
depths depending upon the destination. External word clock synchronisation is possible
using the rear panel BNC connector. The card features two ADAT?-type lightpipe output
connectors. For speeds up to 48KHz both connectors transmit all 8 channels simultaneously.
However, ADAT?-type connectors are bandwidth limited at sample rates above 48 kHz - each
audio channel uses two ADAT? digital channels to accommodate the increased quantity of data,
hence the need for two ADAT? connectors to allow 8 channels of conversion at high speed.
24-bit/96 kHz AES/SPDIF/ADAT? interface card
This card contains exactly the same ADAT?-type digital output facilities as described above,
with the addition of AES and SPDIF format outputs via a 9-pin D-type connector on the rear
panel. As with the ADAT?-type outputs, the full range of sample rates and bit depths are
available, and the converter may be synchronised to an external word clock source if required.
To access the digital signals from the 9-pin D-type AES/SPDIF output connector the A/D card
must be purchased with either an AES or SPDIF D-Type conversion cable, available separately.
Either 8 AES or 8 SPDIF outputs can be used simultaneously with 8 ADAT? outputs and the
OctoPre?s analogue outputs.
With Class A Focusrite processing and almost all the interface options known to man, the
Platinum Octopre is the perfect partner for any Pro Tools system or any other digital audio
workstation, making high quality, multi-channel recording easy. Equally it could be utilised
as an instant location recording solution, or as an additional set of mic pres for any analogue
or digital console, or hard disk recorder.
Please note: The power supply featured in OctoPre is not a switching power supply. Consequently,
120v OctoPres are not suitable for use in 220-240v territories, and vice versa.

| 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 DLX is a one-channel vintage style microphone-, line- and instrument preamplifier. The signal path uses only discrete components like resistors, capacitors and transistors. The line and microphone input and the line output are transformer balanced, using three different transformers, each one optimized for its purpose.
This is the way audio components were built before integrated circuits became available. The subjective sound quality delivered by vintage equipment is often prefered over the one delivered by modern units, a situation that is even more obvious now when music is recorded with clean-sounding digital audio equipment.
The circuit used in the PRE-73 DLX 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.
- Maximum gain on the mic input is 80 dB, enough to handle passive ribbon mics with quiet sound sources.
- Gain range on the Line input: -20 to + 10 dB.
- Switchable impedance on the mic input, 1200 or 300 Ohms, will change the tone of most mics.
- Switchable phantom power and absolute phase.
- A high-impedance instrument input for any sound module, electric guitar or bass.
- A simple but effective 4-step LED output level meter.
- The output level controls makes it possible to make fine gain adjustments and also to overload the main gain stage(s) for more character and then lower the signal to a suitable level before the output stage.
- Combo XLR/TRS input jacks and separate output XLR and TRS jacks for flexible connections.
- Insert jack for inserting EQ´s and other units.
- External high power power supply to avoid interaction with the audio circuits and transformers.
- A solid build quality that will last many years of normal use.
The PRE-73 DLX has a number of improvement and new features compared to the PRE-73 MKII:
- Tantalum capacitors in the signal path.
- Selectable 1073-style high pass filter, 50Hz, 80Hz, 160Hz and 300Hz.
- Output Attenuator -7, -14, -21 and -28 dB (located after the output transformer) allows overdriving the output stage and the output transformer for added character by lowering the output signal to a suitable level.
- The circuit board is prepared for Carnhill Mic and Line transformer and high pass inductor.
- The Insert jack can be switched in/out from the front panel. An internal jumper can select that the Insert jack always has an output signal.
- Switchable 600 ohm Output Termination and Ground Lift on the back panel.
- Selectable Active or Passive DI input and selectable input impedance in active mode, Hi Z or 100 kohm, by internal jumpers.
- The DI can signal can be selected to pass or bypass the mic input transformer by internal jumpers.
- Relays are used to control internal switching for DI input, Phantom power, Mic Low Z, Insert and Phase for shorter circuit board signal paths. The relays are controlled by front panel switches.
- Revised gain switch for added headroom.
- Circuit board star grounding scheme.
- Revised power supply with separate regulators for the audio circuits and relay and LED circuits.
