SONIFEX - SON-RB-DMX4 4X4 CH Digital Audio Mixer/Router The RB-DMX4 is a digital mixer capable of mixing or routing 4 mono input channels into 4 mono outputs, or 2 stereo inputs into 2 stereo outputs. The inputs are sample rate converted to allow sources of different sample rates to be mixed. The flexible Mix Matrix allows for a wide variety of mixing options and creativity, using 4 blocks of 4 way DIPswitches to select which inputs are mixed or routed to which outputs. The RB-DMX4 has 4 x digital mono audio inputs, each one selectable in pairs via front panel INPUTS 1 & 2 and INPUTS 3 & 4 push buttons, from either AES/EBU balanced XLRs, S/PDIF unbalanced phonos or TOSlink unbalanced optical inputs. Sample rate converters on each input mean that sources of different sample rates can be used with the output sample rate being defined independently. The colour of the INPUTS 1 & 2 and INPUTS 3 & 4 push-buttons indicate whether the input source is synchronised (no colour) or not (flashing green and red).

Description Features Two-terminal isolation between input and output Integrated Isolated DC/DC converter Isolation voltage： 2500VDC Operating temperature range:-40℃~+105℃ High speed data rate:1Mbps Complies with ISO11898 standard An unpowered node does not disturb the bus lines Connect upto 110 nodes on one bus Product has complete EMC recommended circuit More Products View More Products

SONIFEX - SON-RB-LI2 Line Isolation Unit The RB-LI2 stereo line isolation unit is used to isolate audio signals from inter-area ground hum loops, which could be caused by equipment being powered by different mains power supplies, or different phases on the same supply. The input and output are connected together through a transformer, which has internal jumpers allowing the outputs to be balanced about ground. There is also a loop-through output, so that the RB-LI2 can be inserted into a line, forming a transformer balanced distribution point. The isolated outputs can be individually adjusted using pre-set potentiometers, accessible through the rear panel. The gain range of the stereo line isolation unit is -15dB to +13.5dB (28.5dB).

The DigiMax D8 is an 8 channel preamplifier featuring 8 award-winning class A XMAX mic preamps with 24-bit ADAT digital output. All eight preamps include variable trim control, 48V phantom power, ultra-fast acting LED metering and 20 dB pad. In addition, 2 instrument inputs are located on the front panel for direct Hi-Z instrument input. Balanced TRS direct analog outputs are located on the rear panel for routing and flexibility. The DigiMax D8 also includes word clock sync input for ultra-low jitter and robust synchronization. The DigiMax D8 is the perfect solution to add eight professional microphone preamplifiers to any digital recording system with ADAT optical lightpipe expansion capability including Digidesign’s HD and 003 systems, RME, YAMAHA, Alesis, Mackie, and many others. The DigiMax D8 includes eight custom-designed high-voltage, discrete, XMAX Class A microphone preamplifiers for all types of microphones. The job of a microphone preamplifier is to boost microphone level signals to line level so that the signal can be converted from analog to digital. This mic to line boost is generally a preamplification of over 400 times the voltage of the original mic level signal. This preamplification stage is one of the most important stages that the signal will go through before converted to digital, and is why a high performance preamplifier is important to achieving great results. All XMAX preamplifiers are built with the same three elements: High Voltage - The XMAX preamplifier runs on power rails of 30V. Most off the shelf op amp based designs run on power rails of 10V to 18V. Higher voltage power rails deliver more headroom, deeper lows, smoother highs and an overall fuller sound. Discrete - No op amps. Only transistors, resistors and capacitors. Op amps add noise, coloration and harshness to a signal. Discrete designs deliver ultra low noise and transparency. Class A - When a circuit is running in Class A mode the circuit is always in an "on" state operating at its optimal voltage requirements. Class A mode has zero crossover distortion and delivers purer, clearer and more musical sonics than class A/B designs which are found in most op-amp circuits. The net result of the XMAX preamp design is high headroom, low noise, wide dynamic range and wide frequency range, and most importantly, musicality and transparency - smooth highs, solid deep lows, and everything in between. Features:    8 XMAX class A microphone preamps w/ trim control 24-bit resolution ADAT digital output 44.1 and 48K sampling rates External sync via BNC word clock input Direct outputs on every channel LED input metering -20dB Pad on every channel 1 year limited guarantee.
