FOCUSRITE PLATINUM OCTOPRE LE 8 CHAN. MIC-LINE PREAMP

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 OctaMic II provides 8-Channel 192 kHz / 24 bit AD conversion with eight hi-class microphone and line pre-amplification channels, featuring a combination of sophisticated components and approved RME technology.

Lowest distortion, excellent signal to noise ratio and perfectly linear frequency response transmit and amplify the microphone signals truly unchanged.

The OctaMic II includes some significant enhancements compared to the OctaMic:

The balanced TRS inputs of the Neutrik Combo XLR jacks are phantom power-free and can be operated as real line inputs too. The improved design of the input circuits allows for a maximum input level of +21 dBu with a convenient gain range from 6 dB up to 60 dB.
Improved signal to noise ratio (SNR) ADC 107.5 dB
Improved THD, especially at higher gains
Optimised heat dissipation by a new and larger housing with improved convection
Internal wide range power supply with line filter, insensitive to voltage fluctuations
Super-stable, short circuit proof 48 V phantom power


Features

OctaMic II offers 8 balanced XLR mic / line inputs via Neutrik XLR/TRS combo jacks. Each channel contains switches for 48V phantom power, a low cut filter and phase reversal. Amplification can be set between 6 and 60 dB. LEDs for signal, clip, and activated phantom power give a complete overview on the unit's status. When the special Clip Hold mode is activated, any detected clip-state will cause the corresponding LED to flash once per second. With this, the user gets a long-term peak detection, and no longer needs to constantly watch the LEDs. At the same time momentary overloads are still displayed correctly.

Frontside switches include power on/off and output level, for a choice of -10 dBV, +4 dBu or Hi Gain (+19 dBu) as reference level. This unusual feature offers two advantages. First, the reference level can be easily switched to match any of RME's current interface devices, from HDSP 9632 through Multiface up to the renowned ADI-8 series converters. Second, the Signal to Noise ratio is optimized, and the Clip-LED will exactly match the ones of the ADI-8 (2 dB below 0 dBFS).

The balanced line level output signal is available at the back of the unit via 8 stereo TRS jacks. The specially developed, internal hi-performance switch mode power supply lets the OctaMic II operate in the range of 100V to 240V AC. It is short-circuit-proof, has an integrated line-filter, is fully regulated against voltage fluctuations, and suppresses mains interference.

AD-Conversion

The 8-Channel AD-conversion of the OctaMic II operates at up to 192 kHz. The digitized signal is available simultaneously at the double ADAT output (S/MUX, up to 96 kHz), and at a DB-25 connector (4 AES/EBU outputs, up to 192 kHz). The digital part can be clocked internally (master) and externally via word clock, AES/EBU and SPDIF.

RME's outstanding SteadyClock(TM) ensures perfect AD-conversion, as jitter on the external sync-sources is nearly completely removed. All settings are done via DIP-switches on the back of the OctaMic II. Analog outputs and both digital outputs operate fully simultaneously. The choice of reference level affects the analog outputs only, the signal/clip indication and the AD-conversion will react only to the Gain-pots.

The CPR12 is an easy to use, flexible and multifunctional 10 channel pre-amplifier. Six of these input channels are selectable between Mic / Line level and equipped with a 3 band tone control. The first two can be switched to priority and phantom power. The other four channels are direct line inputs.

Every input channel has its own gain and fader volume control with PFL button which makes it possible to pre-listen each input or output channel with the built-in pre-listening speaker, and can be routed to one or both output channels. This makes the CPR12 a full two-zone system.

Other present features are a priority input, a recording output, separate sub-out channels and the 24 V DC emergency power connection. This last feature makes it possible to power the CPR12 with emergency power when the main power is shut down. In this case, the priority input will automatically mute all input signals, and a evacuation message will be announced. The steel 19" housing has a height of 2 HE.

PreSonusʼ popular Class A XMAX preamps are widely lauded for their clarity and transparency. Our tube preamps are beloved for their warm, smooth sound. With the Blue Tube DP V2 dual-path mic/instrument preamp, you get both types of high-quality sound in one unit.

Now weʼve improved on the classic unit with the BlueTube DP V2. The solid-state path now feeds PreSonusʼ top-of-the-line Class A XMAX™ mic preamplifier with 80 dB of variable gain—an upgrade from the original BlueTube DPʼs solid-state stage.

You still get all the secondary features you expect in a professional-grade preamp: 48V phantom power, an 80 Hz high-pass filter, -20 dB pad to control hot input signals, and a polarity-reverse switch. Each channel has an illuminated VU meter so you can visually monitor your input levels.

A Tube Drive control provides a wide range of sounds: when itʼs clicked off, youʼre using the solid-state preamp for quiet, transparent amplification; when itʼs engaged, your signals flow through the tube preamp, and you can achieve anything from gentle warmth to edgy distortion.

    2 input channels, each with:
        High-headroom Class A XMAX™ mic preamplifier with 80 dB gain range
        12AX7 vacuum tube gain stage
        Tube Drive tube-saturation control
        48V phantom power
        80 Hz high-pass filter
        -20 dB pad to reduce hot input levels
        Polarity-reverse switch
        Illuminated analog VU input-level meter
