Amplifiers

IWA In-Wall Amplifiers with BluetoothStereo amplifier units for background music and public address in a minimalist housing for installation into cavity walls and ceilings. Class-D amplifier design operates cleanly and efficiently with minimal heat dissipation, combined with an internal digital switch-mode power section, which enables easy connection directly from the local mains supply. Bluetooth compatibility enables wireless streaming of audio files from a smart phone or other enabled device in addition to 3.5mm Aux input and an optical digital audio input, ideal for integrating into A-V systems. For discreet and trouble-free installation without any need for table-top or cabinet installation,…

dimensions 44.5mm x 107mm x 89mm, Input Connections: XLR female balanced, unbalanced, and RCA type phono jacks, Output Connection: XLR male balanced, 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, totally passive audio interface that uses a pair of high performance transformers to totally separate input and …

The Radial StageBug SB-4 is a compact active direct box that has been optimized for use with piezo transducers. This enables violin, dobro, mandolin, cello, upright bass and other instruments that are best amplified using a piezo to be connected without compromising the tone or frequency response. The design begins with a 1/4 "" input for the instrument pickup. Unlike typical direct boxes that have a 1meg-ohm input impedance, the SB-4 features a very high 5meg-ohm impedance that smoothes out troublesome peaks that give piezos a bad name. The higher impedance also broadens the frequency response for a more natural and pleasing sound. The active circuit performs the high-to-low impedance conversion …
