- With improved 192 kHz sample rate for the best sound reproduction.
- Supports uncompressed 2-channel LPCM (Linear Pulse Code Modulation) audio signals.
- Supports compressed 2-channel and multi-channel Dolby Digital and DTS audio signals.
- Ideal for presentation or distribution to another room.
- The optical (Toslink) digital audio splitter can split a single optical digital input to four outputs without delay or loss of quality.
- Supports the S/PDIF and Toslink standard.
Your TV has 1 Toslink output, but you use 4 amplifiers. This requires the Toslink cable to be split from 1 into 4. An additional amplifier could be, for example, a surround set, a sound bar of an amplifier in the kitchen

| More sound to your amps and speakers
The secret to making speakers sound great lies with the crossover you use. With the dbx® 234xs Crossover you'll get great performance, ultra low-noise, rugged reliability and four decades of dbx knowledge and expertise in building the world's finest processors. The 234xs uses precision filters to separate the audio signal and direct the correct frequencies to your loudspeaker drivers. By directing only the specific frequency bands to each speaker driver the 234xs leaves your amplifiers free to use their full power on the usable signal eliminating distortion and giving your PA system a cleaner and better sound.
The dbx 234xs is a dual channel crossover with all the features you would expect from a professional product. It features Linkwitz-Riley 24dB per octave filters, independent output gain controls for level matching, output phase inversion, 40 Hz low cut filter, and optional mono summing of the low frequency (subwoofer) output. Everything in the design exudes great precision from the solid "click" controls to the high quality XLR inputs and outputs.

| 1231 Dual 31-Band Graphic Equalizer
The dbx? 12 Series were designed to meet the needs of the most demanding sound reinforcement environments, while offering the simplicity of straightforward controls. The 1231 provides standard features like dual-channels, 31 1/3 octave bands, ISO frequency centers, +/- 12 dB input gain range, and switchable 40Hz/18 dB per octave low-cut filters, but also includes other insightful features. These include 45 mm faders; selectable +/-6dB or +/-15dB boost/cut range for precise gain adjustments; XLR, barrier strip, and 1/4'' TRS connectors for installation ease; balanced inputs and outputs for quiet operation; and chassis/signal ground lift capabilities for quick hum isolation. The visionary design of the dbx 12 Series makes your job easier.
The dbx 12 Series Equalizers were precision engineered to provide years of maintenance-free operation in any application. The magnetically isolated transformer, electronically balanced/unbalanced inputs and servo balanced/unbalanced outputs, RF-filtered inputs and outputs, and power-off hard-wire relay bypass with 2 second power up delay were steps our engineers took to ensure compatibility for all installations. Only the best components were utilized, yielding a 10Hz to 50kHz frequency response, greater than 90dB SNR (ref +4dBu), less than 0.005% THD +Noise (1kHz at +4dBu), and interchannel crosstalk of less than -80dB from 20Hz to 20kHz. All this attention to detail is contained in a 3U steel/aluminum chassis.

Today?s venues face a growing need to provide a multiplicity of audio feeds from presentations, conferences, orchestral performances and lectures. The advent of digital broadcasting, the growth of webcasts and direct-to-CD archiving highlight the deficiencies in audio splitting systems more than ever before. Whether the final product is a broadcast feed or CD sales of an unrepeatable lecture, performance or event, end-users? expectations of audio quality are higher than ever.With these requirements in mind, ARX has developed the MSX 8 Active Microphone/Line Splitter to deliver the performance required by today?s standards of audio production. Active microphone and line splitting has a number of benefits over passive splitters: primarily these are improved sound quality, noise figures comparable to the best microphone inputs, and increased resistance to RFI. All of which translate into superb audio quality for your clients. About the MSX 8 The MSX 8 consists of two channels of actively buffered ultra low noise Microphone/ Line Splitter. Each of these channels has four electronically Balanced splits ? two on the rear panel, plus two more on the front panel. All four output splits have the option of transformer balancing if so specified.Each channel has a ?20 dB pad switch plus silently switchable 48V Phantom power with indicator LED.Gain through the MSX 8 can be set individually by the small DIP switches on the rear of each channel, from 0dB through to +40 dB in 10 dB stepsA ?Link? switch links Channel 1 to Channel 2, providing an ultimate maximum of 8 Outputs from a single input. An indicator LED shows when this is active. A Clip LED indicates imminent signal overload through the channel, and a numbered marker panel on the front provides a space where individual channel connections can be noted.For remote or mobile applications a 5 pin DIN connector on the rear panel provides an access point to connect a 12V DC power supply Inside Information Internally, powerful RF input filtering removes both common mode and differential interference at ultrasonic frequencies and above. High CMRR is achieved by the use of precision components throughout.Advanced user options include internally jumper linking Inputs to Main outputs, and Ground lifting Output Pins 1as required. Internal Power Supply The MSX 8 has a low noise transformer based power supply to obtain the maximum benefit from the ultra low noise design of the splitter circuitry. Summing up, the feature packed MSX 8 is the answer wherever transparent signal buffering and routing is required.
