AMC CVT1030 Series - CVT1030MKII

AMC CVT1030 Series - CVT1030MKII

 

AMC CVT1030MKII

* AMC CVT1030 Series updated to CVT1030MKII at 2011 according to AMC Users' requirements to add Remote Control & Pre-out new features into CVT1030 Series.

* For features, Installations-Operation Instructions & specifications of AMC CVT1030MKII, please refer to CVT1030MKII Manual attached.

* AMC CVT1030MKII received superb Review in Stereoplay, Germany 2012-09(Sep) issue as attached.

* AMC CVT1030MKII is one of the AMC CVT Series with Vacuum Tube topologies designs using the high voltage FET exactly as Vacuum Tubes as FET's and Vacuum Tubes are with the same majority current structure and with the same transfer function but FET does not require flament, so it is much higher efficient with much better accuracy on all respects and with much higher reliabilities.

* For the output stage of AMC CVT1030MKII, AMC designed with Vacuum Tubes as usual for taking advantage of Vacuum Tube characteristics and sound quality will be kept the same good quality during the whole life of the output stage Vacuum Tubes.

* For headphones output, it passes through the Vacuum Tube topology High Voltage FET Tubes pre-amp for delivery Class A vacuum tube sound. And for output stage for headphones, AMC designed with high speed amplifiers with internally phase-compendated gain and 3.0V/uS & fT=10MHz high slew rate with low noise of 1.8uVrms. So, the headphones outputs can drive all types of headphones with various impedances comfortably. As AMC designed headphones outputs with pure resistive, so, the sound quality of headphones will be depending on the characteristics of headphones users will use.

When user is listening music from Headphones outputs using heaphones, user can switch "Direct / Normal / Phones" switch to "Direct" for bypassing Bass & Treble Tone Controls for those music lovers they like to enjoy more pure sound quality. Or switch the switch to "Normal" to activate Bass & Treble Tone Controls for those music lovers like to equalize sound field to fit each rooms accoustic characteristics. When users switch the switch to "Direct" & "Normal" positions, there are music from Speaker terminals simultaneously. When users switch the switch to "Headphones", there will be no music from Speaker terminals and Bass & Treble Tone Controls are activated.

* For "Direct / Normal / Phones" switch, please don't switch it until 5 minutes after turning CVT1030MKII on or you will hear some switching pop sound as CVT1030MKII has been designed with very high voltage and initially will require around 5 minutes for building up the high voltages. As adding extra ccircuits would degrade the sound quality due to longer time constant and AMC developing engineers decided to be without them. So, AMC would like to suggest users to wait for 5 minutes before starting to switch the switch. Then there will be without the pop sound and sound quality will be better.
