Streaming Receiver

The Streaming Receiver

The CALA® SR is one of our most elegant products. It is designed with the purist in mind, manufactured using only the finest materials available, and equipped with the very latest technology. If wished, the plinth of CALA® receivers can be illuminated, since we have integrated an LED strip light in the rear part of the machine’s backplate. For ambient lighting you can choose between different color modes and white, blue, green and red light, and the intensity of the lighting is user-variable.
It is a compact, relatively small multi-talent to which the term “receiver” no longer does justice. In truth it forms the universal command centre of a complete Hi-Fi system. In spite of its small dimensions it contains a fully-featured integrated amplifier with a tremendous range of connection facilities, with powerful output stages capable of superb sound. Our developers have worked the miracle of integrating all the essential music sources into a case which already houses the integrated amplifier function. The CALA® SR deliberately eschews a CD mechanism, because many present-day music lovers have replaced the CD with streaming or music services; this philosophy also allows the case to maintain a more compact format. The CALA® SR has everything the listener requires for the enjoyment of music.


From the point of view of overall design philosophy and technical facilities the CALA® receivers are close relatives. They are equipped with the same motherboard and software and have access to the same music sources. 
The connection sockets and facilities of both receivers are identical. The analogue input A1 IN can be configured as Surround Pass Through, and the sensitivity of the analogue input A2 IN can be switched, so that it can be used as a phono pre-amplifier for MM and High output MC systems. One pre-amplifier output and one digital output are also present. Digital inputs include two optical and one co-ax types. These can be switched off if necessary, in which case they no longer appear in the menu. Access to new music media and services is possible via the LAN socket or the WLAN aerial. The USB port is ideal for connecting hard discs and memory sticks.

Since the integral FM / DAB+ tuner provides very strong reception, it makes sense to connect a high-quality external aerial to it.
The solid metal loudspeaker terminals can accommodate cables of large cross-section, and an active subwoofer output socket is also present. T+A has concluded a service contract with the Airable Internet Radio Service company, which enables purchasers of our streaming client products to create individual station lists and favourites lists at no charge; these lists are then made available automatically when Internet ratio is selected.
The receivers are controlled using the FM1000 infra-red remote control handset, or – ideally – the T+A MusicNavigator APP. In contrast to many manufacturers’ apps, this is capable of controlling every element of every function of our machines. Not only does it display the information pertaining to the streaming client, but also the screen content of all sources, such as the station name and radio text when used in FM radio mode.
