Introduction
Thank you for purchasing an AVI Laboratory series DAB Tuner. As the name implies, it is a precision instrument, meticulously hand built and tested and, given the right circumstances, will produce the best sound quality that current technology will allow.
We recommend that before you use your new tuner, you carefully read the instruction manual. If you are familiar with the way the machine works before you start, you are much less likely to encounter problems.
Installation
The Laboratory Series Integrated amplifier has been designed so that your tuner can be put on top of it provided it is well ventilated. In cupboards where air cannot circulate it would be best to put them side by side or, if you are using another make of power amplifier that gets warm or even hot in use, then do not put the tuner on it, as high temperatures can damage it.
Use good quality, screened coaxial phono-to-phono leads, avoiding ones that lock and always makes sure that force applied to plug in or remove leads is directly in line with the sockets. This is to minimise the risk of damage.
AVI products are extremely reliable but we do occasionally get units back for repair because the phono sockets have been damaged. This is because many people believe that cables can be used to fine tune the system or overcome some problem with sound quality. Usually their problems are quite severe and cable will not help. The biggest differences are caused by room acoustics and to a lesser extent, loudspeakers. If you are in trouble, we may well be able to help so please get in touch.
As a general rule it is not a good idea to remove and replace cables whilst the system is switched on. The pops, clicks and hums that can occur may damage loudspeakers especially if you amplifier is quite powerful.
Instructions for use
In the majority of cases your DAB tuner requires a high quality external aerial and these can be obtained from and installed by a local specialist. We do not recommend internal ones.
The aerial socket, known as an F connector, forms part of the receiver so it is important not to damage it because if you do, the repair will be extremely expensive. Your local installer will provide the correct cable and connector. Use nothing else as forcing wires into the socket will break it.
When the tuner is switched on for the first time it will be out of standby and need to be tuned. On the left rear panel (looking from the front of the tuner) there are two small buttons labelled Tune and Reset.
The tune button has two functions, if it is pressed and released it will scan band III (UK frequencies) and store all the available stations. If it is pressed and held for five seconds it will scan band III (UK) and L Band (some Continental) and memorise all available stations. All you need to do is chose a suitable option and you will have all the stations you can get. The tuning knob rotates in a series of
