Tested and all channels work . IEC power cord.

Ich verkaufe diesen hervorragenden Multiroom Verstärker wegen Systemumbau. Der Verstärker ist technisch einwandfrei und bespielte bis vor einem Monat noch mein Einfamilienhaus. Ich habe mein System nun auf NAD Bluesound umgestellt und benötige ihn daher nicht mehr. Wie auf den Bildern zu sehen, hat er ein paar Schrammen am Gehäuse. Diese fallen bei einem Rackeinbau nicht auf. Produktbeschreibung Der RKB-D850 ist in puncto Power-Output und Funktionen im Wesentlichen der gleiche Verstärker wie der RKB-850. Doch der RKB-D850 verfügt auch über vier optische digitale TOSLink-Eingänge mit individuellen Stereo DACS für jedes Paar Kanäle, zusätzlich zu den vier analogen RCA-Eingängen. Jeder digitale Eingang unterstützt bis zu 24-bit/192kHz LPCM Audio. Die Endstufen RKB-850 und RKB-D850 haben viele gemeinsame Ausstattungsmerkmale, darunter 12-Volt-Trigger, 5-Wege-Lautsprecherpolklemmen, Eingangs-Verlinkung, einen gepufferten analogen Vorausgang zum Anschließen zusätzlicher RKB-Verstärker und eine IEC Power-Anschlussbuchse mit abnehmbarem Kabel.

ROTEL RKB-D850 V2 (READ: POWERS ON, NO SOUND) MINT CONDITION. LISTED AS PARTS ONLY. AS IT IS. NO RETURNS. ROTEL RKB-D850 V2 Distribution Multi-Room Audio 8-Channel AmplifierAuction Includes:Rotel RKB-D850 Amplifier V02Power Cord (12 ft long)NO ORIGINAL BOX. Will be shipped with padded packaging. Product Description The RKB-D850 is essentially the same amplifier as the RKB-850 in terms of power output and features. However, the RKB-D850 also features four optical digital TOSLINK inputs with individual stereo DACS for each pair of channels in addition to the four analog RCA inputs. Each digital input supports up to 24-bit/192kHz LPCM audio.The RKB-850 and RKB-D850 share many common features including 12-volt triggers, 5-way speaker binding posts, input linking, signal sense, a buffered analog audio pre-output to connect additional RKBs, and an IEC power receptacle with detachable cord.RKB-850, RKB-D850, RKB-8100 and RKB-D8100The amplifiers come in two eight-channel configurations at 8 x 50 watts and 8 x 100 watts RMS per channel into 8 ohms, all channels driven. All RKBs can double that output into 4 ohms as a result of their sophisticated, efficient Class D design. The amplifiers are rugged and extremely reliable, but Rotel has taken additional further precautions to maximize service life by utilizing dual thermostatically controlled fans to exhaust heat away from the output modules and power supply.The Digital versions (Designated by a “D” in the nomenclature) feature four TOSlink digital inputs with individual stereo DACS for each pair of channels in addition to the four analog inputs. When a digital audio source is detected on the TOSlink input the unit will automatically switch to the digital input. If an analog input is connected, that source similarly will be detected. No user configuration is required. Each digital input supports up to 24 Bit/192 kHz LPCM audio.All RKB amplifiers share common features such as:Improved input linking. In the previous units, zones could only be linked from A. Now, a second input can source from any ‘upstream’ input - so B can source from A, C can source from B and D can source from C. You can create four individual stereo zones, two dual zones or three common zones plus an individual zone. In other words, two Sonos Connects (for instance) might be divided between kitchen and patio (A+B zones) and Master Bedroom and Bath (C+D).Ideal for use with Sonos Connect.The new RKB amplifiers are not only improved in general functionality and flexibility, more importantly, they can now be tied into Sonos based systems seamlessly. A 3-way switch located on the rear of the amplifiers controls and operates Signal Sensing for both analog and digital inputs (on the “D” versions). In the case of the “D” versions, the signal sense is applied to the circuit post-DAC so it is not fooled by a clock signal. The amplifier stages and certain other circuits are shut down, but the DAC circuit needsto remain on for signal sensing.Additional features:• A rear panel RS232 connection allows automation systems to provide control and feedback. The RKB amplifiers also include four front panel trim pots, which allow easy level adjustment to balance zones.• Never Turn Off - The RKB will always be on, never go into standby. (Obviously the amplifier can be turned off completely using the on/off button on the front panel).• Trigger on/off – when the RKB receives a 12 volt trigger, it will turn on.• NOTE - RS232 On/Off – Can also be turned on or off via RS232 command.• As a safety feature and regardless of mode the amplifier will monitor its temperature. If it rises above a determined level the fans will come on until the unit has cooled down then return to standby operation.• 5-way speaker binding posts• Buffered analog audio pre-output to connect additional RKBs,• IEC power receptacle with detachable cord.• 2U height takes up a minimal amount of rack space and the RKBs can be stacked together without the need for rack spacers to maximize rack efficiency.Choose either the analog-only input models or the digital plus analog input versions as suits the system configuration. In either case, be prepared for an extraordinary audio experience.
