- Overall beautifully musical sound
- Surprising ability to “play” speakers
- A real tribute to the talent of Ken Ishiwata
- Very attractive price tag for the given performances
- Adept for the best amplifier around 15,000 CZK
- At least basic digital inputs are missing ( but again in that price…)
The Rotel brand has been one of the traditional Japanese manufacturers of audio equipment for many decades – specifically since 1961, so this year it celebrates a beautiful 60th anniversary, which could be associated with the popular status of a “legendary brand” . Last year, the company teamed up with another Japanese legend, the now deceased Ken Ishiwata, who did not retire after leaving Marantz, but chose to work with Rotel as his last entry in the Hi-Fi history book.
Specifically, he participated in the tuning of the basic company models of the A series – the CD11 CD player and the integrated A11 amplifier, which components subsequently received the respectful Tribute designation. “), In honor of Mr. Ishiwata.
Appearance and construction
A11 Tribute is a slim product indistinguishable from the original version, only a fairly distinctive sticker with an English inscription and a Japanese symbol point out for a difference. The amplifier is no different from traditional devices of a similar category – in the middle is a small but easy-to-read display with a reasonable amount of information, below it a set of small input dials, in the left part of the panel you can switch between two sets of output terminals with the same buttons.
On the left is a power button and a small headphone jack. On the right, the three buttons are used to move in the menu of the device (which, by the way, is pretty bushy and allows anything from setting tone corrections to dimming the display and LEDs), but there is also a nice volume control.
At the back, two sets of reproterminals, arranged in one line next to each other, occupy the most space. There is also a power socket and five pairs of cinch inputs of a common line form and one cinch pair for connecting a turntable with an MM portable, of course with the necessary grounding pin. Pleasant antenna for Bluetooth connection with aptX codec. The device is also equipped with “smart” connectivity – RS232 port for more sophisticated control systems, two 3.5 mm sockets with 12 V trigger voltage for other components and one small jack for connecting an external remote control sensor (if you have the device in a cabinet, which
Ishiwata took the original concept, selected better components in important places, and easily intervened in the signal topology. ways, which tuned the whole amplifier – in his own words – to a fuller performance.
But the tailor-made company toroidal transformer and its own capacitors remained, it is still a classic “rotelá” transistor amplifier with a decent output of 50 Watts per channel up to 8 ohms, of course in class A / B . The manufacturer boasts a very decent frequency range of 10 – 100,000 Hz ( /- 0.5 dB) and a good value of total harmonic distortion below 0.03%, while the signal-to-noise ratio is over 100 dB, which is also decent. The damping factor reaches 140.
It remains to mention that the A11 Tribute has quite standard dimensions of 43 x 34.5 x 9.3 cm (wxdxh) and weighs 6.85 kg.
