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.

Rotel RKB-8100 8-Channel Power Amplifier - Used and Not Working - Protection Mode - Blinking Light. This was a great amplifier that was in service for several years, amplifying several Sonos Ports throughout my house to provide music in various zones. Twice in recent years, however, it entered into protection mode for no clear reason. The first time I was able to get it serviced within warranty; but it is now out of warranty and I decided to take a different approach to the home audio system rather than continue to try to address whatever is happening here. Maybe you can make it work for you, or perhaps you can harvest it for parts for your repair business or hobby. Note there are minor physical flaws on the exterior (evident from the photos). Power cable included. THIS IS OFFERED AS IS, THERE IS NO WARRANTY THAT YOU CAN GET IT TO WORK OR DERIVE VALUE FROM ITS COMPONENT PARTS. *NO RESERVE*

Ich verkaufe hier einen einwandfrei funktionierenden Rotel Verstärker mit 6 Kanälen. Der Amp ist mit einer Signal Sense Funktion und einem 12V Trigger (Ein- und Ausgang) für das automatische Einschalten ausgestattet. Zudem gibt es noch einen Link-Output und einem Stereo/Mono-Schalter für die Lautsprecherpaare B und C. Der äußere Zustand ist nicht mehr der allerschönste (siehe Fotos), von vorne aber noch sehr ansehnlich. Er stammt aus einem tierfreien Nichtraucherhaushalt. Von einem sehr geringen Abstand lässt sich manchmal ein sehr leises Brummen aus dem Verstärker selbst wahrnehmen. Ich weiß allerdings nicht, ob das an einem sehr unsauberen Verbraucher in unserem Haus liegt, da es nur selten auftritt. Und wenn man nicht bei niedriger Lautstärke der Musik direkt davor sitzt, ist es sowieso nicht zu hören. Den Zustand und die Funktion können Sie vor Ort in Detmold gerne überprüfen. Zwei Chinchkabel mit jeweils drei Kanälen kann ich umsonst mit dazugeben (https://www.kleinanzeigen.de/s-anzeige/2-chinch-kabel-mit-jeweils-3-kanaelen-1-45m-lang/2461763636-172-1794). Leistung: 6 x 50 Watt RMS an 8 Ohm 6 x 80 Watt RMS an 4 Ohm Signal-Rausch-Verhältnis (SNR): 115.0 dB (unüblich viel für diese Preisklasse!) Total Harmonic Distortion (THD): 0,03 % Der Verstärker ist auch für den Dauerbetrieb geeignet. Privatverkauf, keine Garantie oder Rücknahme
