With eight channels of Focusrite microphone pre-amplification, eight VCA-based Red 3-derived compressors and built-in 24-bit / 96 kHz digital inputs and outputs, OctoPre MkII Dynamic is Focusriteʼs feature-rich expansion upgrade for any digital audio workstation. Itʼs equally an ideal expansion for any analogue or digital console, or hard disk recorder.
Digital inputs and outputs let you make the most of often-neglected ADAT i/o; ideal for expanding the number of mic-pre inputs on your interface or for providing analogue monitoring from any digital ADAT feed.
With this entire package fitting into a single 1U chassis complementing Focusriteʼs Saffire PRO range, and all controls adjustable from the front fascia, OctoPre MkII Dynamic sets the standard for modern, compact, multi-channel recording expansions. | • 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.

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. ![]()

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.
