The PDB™ Passive Direct Box is a rock solid, roadworthy DI for connection of the outputs of electronic musical instruments (or other audio sources) to the balanced inputs of mixer consoles and other balanced inputs.The PDB™ also allows connection of a music source to an instrument amplifier while simultaneously patching it to a mixer.PDB Applications:Electric guitar and bass pick up output signals – The high impedance signal from a guitar or bass guitar pickup is translated by the PDB™ into a low impedance balanced signal required by mixing consoles.Keyboards and line level signals – The PDB™ automatically balances and matches the line level outputs of modern electronic keyboards. If you are using a multiple keyboard setup and your keyboards are all plugged into a single instrument amplifier, the PDB™ can be used to replace individual direct boxes. Simply send the output of the instrument amplifier to the PDB™ and then to the console (instead of a separate DI box for each keyboard).DJ console output signals – DJ mixers often supply only an unbalanced -10dB signal. The PDB™ converts this signal to a balanced line level signal before it reaches the console, while providing a convenient method of connector transition with the capability to run long cables.Speaker level signals – The PDB’s ability to accept speaker level inputs from a power amplifier’s output allows post-amplifier, post eq and effects signals to be fed directly to the console. In this manner, a particular effect or amplifier sound can be sent directly to the mix.SpecificationsFrequency Response: 10 Hz – 50 kHz +/- 0.5dB @ +4dBuOutput Connections: 600 O XLR Output JackGround Lift: SwitchableInput Attenuation: Switchable (0dB, -20dB, -40dB)Instrument Input: 50k OParallel Link Jack: 50k ODimensions: 3" x 5" x 2"

With processing for 4 inputs and 8 outputs it takes advantage of the latest analogue to digital conversion and DSP technologies to deliver flawless audio that out classes its competition.The advanced 96kHz DSP provides an array of unique and genuinely useful features. Because all aspects of the DSP algorithms are designed and hand crafted in house by Linea, they are not available on products from any other manufacturer. For example, LIR linear phase crossover filters which are as easy to use as more conventional filter shapes, and have less latency than FIR filters. Also the powerful VX Limiter suite which sports Peak, RMS and Excursion limiting, as well as multiband limiting for passive 2-way enclosures.Supporting analogue AES3 inputs and having both analogue and AES3 outputs, all under full remote control, makes the ASC48 suitable for use in the most demanding applications, especially when flexibility is paramount.When used as a loudspeaker management system or digital crossover, the ASC48 brings state-of-the-art facilities and performance, however the ability to receive, process and transmit audio without it leaving the digital domain makes the ASC48 an ideal central controller for large systems, even when amplifiers with in-built DSP are being employed.Ethernet is used for remote control while a front panel, optimised for use in challenging environments, allows full local control of all features. Control via Linea’s intuitive System Engineer application provides many convenient and time saving features such as very flexible management of presets, and Overlay grouping of Mutes, Gains, Delays and EQ across an entire system.

ART DTI Dual Transformer/Isolator - a high quality, totally passive audio interface that uses a pair of high performance transformers to totally separate input and output signal grounds, thereby isolating two systems and reducing hum and ground-loop noise. The DTI's audio transformers have an extremely flat and wide frequency response and can handle high signal levels while maintaining an isolated balanced output. This gives the DTI a very clean and neutral sound with a wide variety of signal sources. The transformers are wound for 1:1 unity gain and are designed to be used with impedances from 600 Ohms to 100 kOhms, Input Connections: XLR female balanced, 1/4" TRS, unbalanced, and RCA type phono jacks, Output Connection: XLR male balanced, 1/4" TRS, unbalanced, and RCA type phono jacks, Dimensions 44.5mm x 107mm x 89mm, Weight 0,34 kg
