DarTZeel CTH-8550 MK2 Integrated Amplifier

Quick Overview

darTZeel CTH-8550 Integrated Amplifier.


This product combines in one casing most of the good things musical lovers found in our flagship NHB series. The CTH-8550 features newly designed power output stages which include on board regulated power supplies for a very compact global layout. This new circuit brings outstanding transparency, speed, yet delicacy, giving a maximum listening pleasure. With no less than nine inputs in total, the preamplifier section is dual-mono – one dedicated circuit per channel – with a minimal footprint which allows for very short signal paths. No doubt that this newcomer is a true darTZeel machine. Key features include: * A newly designed fluorescent display for user-friendly operation. * 7 standard inputs blended from a mix of Zeel, RCA and XLR sockets. * 2 additional, optional Phono inputs (1 MC, 1 MM), easy to implement at any time (factory upgrade only, though). * Full HT bypass function for all inputs. * 1 darT preamp output for driving an external NHB-108 power amplifier. * 1 RCA preamp output for driving any other optional power amplifier. * 1 RCA REC output, with independent record source selection. * A fully featured remote control, 100% darTZeel designed. * A new kind of approach in mechanical housing design thanks to state of the art Laser cutting & welding technologies, ensuring unprecedented high rigidity and easier assembly and maintenance procedures.
