Square ONE 8-Channel Mic Splitter

SQUARE-ONE-SPLITTER

The Square ONE Splitter provides a simple solution with a high-performance, Midas XL8-inspired pre-amp design.  Packaged in a 2RU, eight-channel format.

To increase versatility and provide additional value, a third set of transformer-isolated independent (fixed gain) outputs are provided in addition to the Square ONE Splitter's ability to function as a 1:16 media split.

Features:

• Midas XL8-inspired mic preamps with a dynamic range of >140dB.  With an extremely high CMRR that accommodates input levels up to +22dBu.
• 9-Position rotary gain switch per input - A simple 5dB resolution 'stepped' rotary control to provide gain adjustment for both main outputs from 0dB to +40dB to easily match any signal level (mic or line).
• 30 Hz Hi-pass filter with switch and status LED per input - Eliminates unwanted subsonic information, increases headroom in the mixing console inputs, amplifiers and loudspeakers.
• Inputs duplicated on front and rear panels - for convenient connection options, either internal to the patch rack, or directly into the front panel.
• Transformer-isolated gain-independent outputs - Located on the front panel for easy connection of recording devices and outside broadcast facilities. Transformers provide superior galvanic isolation; fixed-gain status prevents unexpected changes in level during performances.
• Front-panel and remote 48V switching with status LED per input - Phantom power activation can be switched remotely from the +48V supply on any mixing console connected to the electronically balanced outputs.
• Solo bus with integral headphone amp and level control - Allows the mic amp performance and level to be monitored directly from the front panel. Also an invaluable aid when fault-finding in line systems.
• 1:16 media split function with front and rear panel status indication - Input 8 can be routed to ALL 16 rear-panel XLRs simultaneously via a single recessed switch on the rear panel. Ideal for press feeds and many other multiple-signal distribution applications
• Separate ground lift switch with LED status indicators for each set of rear panel outputs - Eliminate hums, buzzes and other ground-related undesirable audio artefacts.
• Individual 4-Segment LED output metering for each input - 3 colors, easy-to-see instant status indication (-15, 0, +12, +21dBu)
• 2 RU all-steel chassis
• Universal power supply - Auto voltage sensing, operates anywhere between100-240V (±10%).
