MX-A5000
Overwhelming Power and High Density Presence Achieved by 11.2-channel Separate AV Amps
The MX-A5000 discrete structured 11-channel Power Amplifier delivers powerful driving force that provides superb quality and performance for all channels. Combined with the CX-A5000 11.2-channel Pre-amplifier, it achieves overwhelming silence and sound filled with dynamic feeling, the goal to which Yamaha constantly aspires. With all types of sound sources, you will enjoy a deep resonance that immerses you in music with the full scale presence of 11.2 channels.
Stabilt chassi säkerställer att inte vibrationer påverkar ljudkvaliteten negativt
As part of the no-compromise design policy for these two amplifiers, Yamaha created an advanced chassis with strong rigidity. Chassis stiffness is enhanced by an H-shaped cross frame that boosts mechanical strength, by adopting aluminium side panels that increase the stiffness of the housing, and by a three-ply structure with independent top cover and side panels. Any external vibration from the rack or other sources is damped by heavy insulators. The A.R.T (Anti-Resonance Technology) Wedge in the centre of the bottom cover acts as an additional vibration countermeasure and firmly supports the internal circuits and delicate parts. In addition, the MX-A5000 has a double bottom, consisting of vibration control plates made of 1.6mm black steel, the same type of construction used on the previous flagship model Z11. In order to support the heavy heat sinks and other parts, it has a left-right independent construction strengthened by a rigid-frame structure. The bottom frame reduces the transmission of vibration produced by the large power supply transformer and heat sinks. It also incorporates a heavy insulator that blocks external vibration.
Symmetrisk förstärkarlayout
Detta är bara en av många detaljer som bidrar till att skapa en receiver med överlägsen ljudkvalitet. Enhetens interiör har blivit planerad in i minsta detalj och byggts så att den vänstra och högra kanalen är både fysiskt och elektriskt isolerade. Detta maximerar kanalseparationen och förbättrar signal-brusförhållandet enormt vilket också bidrar till att uppnå en bred och öppen ljudbild.
Highest Quality Parts Achieve High Power to 11 Channels and Unrestricted Speaker Drive
The MX-A5000 uses a current feedback power amp with a Three-stage Darlington circuit that has superior phase properties and is resistant to speaker impedance fluctuation. To fully realise its inherent power, it uses high quality parts with superior sound quality that were strictly selected based on listening tests. The power supply transformer is a specially developed high output, high efficiency, large size toroidal transformer. With two specially developed high capacity (27,000uF) block capacitors, it minimises energy loss and features power supply capacity with generous headroom. This ensures sound capable of superior musical expression. The speaker output terminals are high quality gold-plated types, and are compatible with Y plugs for optimum speaker connectivity.
Minimal påverkan från yttre störningar med balanserade ingångar
Elektriska störningar kan genereras i ett system när man kopplar samman olika AV-komponenter samt när en signal färdas genom en kabel och utsätts för yttre störningar. För att säkerställa att MX-A5000 och CX-A5100 inte påverkas av denna distorsion så använder vi oss av balanserade anslutningar (XLR)- samma typ som vi använder i våra professionella mixerbord bl.a. Även våra obalanserade RCA-anslutningar använder en jordavkännande överföringsmetod som fungerar som en enklare balanserad överföring. Om alla kanaler används med XLR så elimineras störningarna som kan uppstå från anslutningen mellan enheterna.
In Addition to 11.2-channel Output, 5-channel Biamping and Other Configurations Are Possible
The MX-A5000 and CX-A5000 are designed to allow flexible system building. Complementing their 11-channel output that maximises Cinema DSP HD3 performance and makes the most of the capabilities of the speakers, they also support biamping for driving tweeter and woofer with separate amps. Furthermore, they allow biamping of, for example, all five channels using the 11 internal channels. Extra amps can be used to power multiple zones in addition to the main room, letting you configure your system for music play in a bedroom or kitchen, for example. On the MX-A5000, you can switch all 11-channel input jacks back and forth between balanced and unbalanced for each channel, further increasing system flexibility.
Automatisk "Stand By"-läge
Att använda mindre ström är både bra för planeten och för plånboken. MX-A5000 har en funktion som automatiskt sätter den i "Stand By" efter 8 timmar. Funktionen kan slås på och av via en knapp på baksidan, alternativt styras via en triggerfunktion.
Trigger Control for Synchronised Power On/Off
The trigger function allows automatic power synchronisation with other components that support this function. Connecting a preamp, for example, to the Trigger In jack turns the power on and off together with the preamp. Connecting another component such as a subwoofer to the Trigger Out jack syncs the power of that component to the MX-A5000. In addition, the input from the Trigger In jack can be output in a cascade connection to control the power of another component such as another power amplifier (Through Out).
Ställbar impedans
De går att ställa MX-A5000s impedans på baksidan av enheten för att säkerställa optimal prestanda med alla sorters högtalare.
CH.2 A/B: 4 ohm eller mer (8 ohm eller mer när du använder CH.2 A och CH.2 B samtidigt)
Andra kanaler: 6 ohm eller mer
