Features
Case & Tubes
The excellently crafted, deep glossy case is probably the first thing that positively strikes you.
This metallic design looks good, but at the same time provides the necessary protection for the electronics. Nevertheless, the attention first falls on the total of eight tubes. In the rear area, that would be four KT88 output tubes. They provide the power amplification. In the row in front of them are four identical looking, smaller glowing tubes.
However, a closer look reveals that they are two different models: Two 12AU7s sitting on the outside and the two 12AX7s placed in the middle.
While the 12AX7s act as preamp tubes and amplify the voltage level of incoming music signals, the 12AU7s serve as phase splitters and drivers for the KT88s. In keeping with this, the developers have placed emphasis on a cage that has been painted in the same color as the cabinet.
This appears to be a more advanced, and it protects the high-quality tubes from mechanical damage.
As if all that were not enough, the Jazz 80 stands on four shock-absorbing feet.
Bluetooth/LDA
In addition, there is a Bluetooth module in the units. Communication wirelessly with appropriate players such as smartphones, tablets, laptops or even the TV is possible This turns the HiFi specialist into a modern audio centre.
The connection setup is very simple:
- If the input source “Bluetooth” is selected, the small blue LED flashes.
- At the same time, the Cayin identifies itself as “Cayin HD BT” to its potential play partners.
- Now, a tap of the finger is all it takes to connect the external player and Jazz 80 wirelessly.
The transmission is done via LDAC codec. LDAC stands for “Low Delay Audio Codec” and allows the wireless transfer of high-resolution audio content at a maximum transfer rate of up to 990 kbps. This should especially please smartphone owners with Android operating systems from version 8.0 onwards.
Ultralinear and Triode mode
The Jazz 80 can be operated in both Ultralinear mode and Triode mode. This makes the amplifier even more flexible. Both modes each have their own sound characteristics.
With its pre-installed KT88 output tubes, the Cayin outputs 2×20 watts in Triode mode. In Ultralinear mode, on the other hand, it’s even a whopping 2×40 watts of power. The switchover is easily done via a small toggle switch, which finds its place directly in front of the two 12AX7 tubes.
The power supply.
The Cayin team have made full use of their resources and given the Jazz 80 an elaborately designed power supply including a filter choke.
Bias circuit
Right next to it the modes, there are three more toggle switches, one on the left and two on the right. They help to control the correct bias setting.
This can be adjusted individually for each output tube via trim potentiometer.
- The center toggle switch turns the left VU meter into the control element for bias adjustment.
- The left lever (A1/A2) controls the tubes for the left channel
- The right one (A3/A4) controls those of the right channel.
This gives perfect control of each tube and at the same time for clean balancing of all channels.
Simple Operation
The Jazz 80 is switched on via a small switch in the left side panel. A gentle click and the lighting up of the VU meter means it is ready to use.
As long as the small LED indicator in the volume control is blinking, the soft start-up is running. The Cayin is warming up first.
If the LED is permanently on, then system is ready to go.
The input selection can now be made either via the rotary control on the left in the front or via the input button on the high-quality aluminum remote control. Volume selection can be done either via the level control on the right or via infrared remote control.
