Integrated Amplifier
One of the purest amplifiers in the high-end audio world is the Integrated. Built just for music in the most uncompromising way: it has only the volume control and an input selector in the signal chain. When connected to the mains, the amplifier is automatically set to 'stand-by' as there is no power-on-switch. The quiescent current of the output-stage is switched off and the signal is muted through the dedicated switch on the front panel.
As with all Brinkmann Audio components the top plate is made from tempered glass allowing the owner a view to the internal beauty of the Integrated amplifier There are four line and two digital inputs, the latter drive the optional vacuum tube driven DAC-module. The signal is fed directly to an Alps-pot via the input selector and then sent through the active electronics, thus the Integrated should be seen as a combination of a high sensitivity stereo power amplifier with passive preamplifier. In addition to that, there's a buffer stage for the tape recording output that carries the signal of the chosen input. There is also a dedicated headphone amplifier that is activated when the Integrated is in stand-by. The Headphone-output-socket is located on the front panel and the relative circuit has been optimized for headphones with an impedance of at least 200 Ohms. To make the amplifier become a truly digital device there is the optional DAC-module: its current-to-voltage stage is built using a small signal triode voltage tube. The digital signals of CD-players, DAT recorders or digital Tuners may have sample-frequencies from 32 to 48 kHz, the DAC-module is automatically adjusts itself to the input frequency. The two digital inputs are switched electronically: when a signal reaches Digital 1, the output-tube is heated independently from the input chosen, i.e. the tube can be pre-heated by switching on a digital signal source while a different line input is working. An aluminum hand held remote for volume and mute is now standard equipment.
