Music Source In Exceptional Sound Quality

CALA CDR
CALA CDR

The Streaming CD Receiver

The CALA® CDR is the larger model in the CALA® Receiver range. From the point of view of overall design philosophy and technical facilities the machine is a close relative of the CALA® SR, but it also features a high-quality CD mechanism, output stages with twice the power, and a high-performance mains section. 100 Watts continuous power is available per channel, which is ample for use with large loudspeakers. To accommodate these additional features the case is larger and heavier, but it remains very compact, and maintains the same overall design and proportions as the CALA® SR. Since both devices are based on one and the same motherboard, their music sources and connection facilities are also identical. 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.

The machine’s high-performance digital signal processor makes it simple and convenient to set it up to suit individual system configurations. For example, it is possible to switch off inputs which are not required, and the sensitivity of one analogue input can be switched to act as a phono MM and High output MC preamplifier. For operation in a surround system the device features a Surround-Pass-Through Mode. A further feature is a range of sound fields designed to achieve optimum sound quality under a variety of conditions and positions, catering also for relatively small loudspeakers. A bass management system regulates all settings if a subwoofer / satellite system is employed.

Technology

For the CALA® receivers T+A has developed an ingenious fully digital design principle which performs the entire signal processing in the digital domain. This provides a crucial improvement in sound quality, since it eliminates the need for the additional conversion of digital sources; all the data processing is carried out consistently in HD audio quality. The CALA® is a versatile, fully featured receiver with a great performance, and this is only possible through the use of the latest technologies and components. All the audio signal processing is carried out by a high-performance digital signal processor which generates the sound fields for various set-up conditions and virtual surround, controls – where necessary – all the tone settings and cut-off frequencies for the primary loudspeakers and sub-woofer (bass management), processes and controls the output signals for the speaker channels, and converts the two analogue inputs into digital data, so that these can also be processed digitally. The integral amplifiers are based on high-speed bridged switching output stages with high continuous power and current delivery capacity. Their output is sufficient even for large loudspeakers and spacious listening rooms. A mains section which is very stable under load makes ample energy available at all times. Naturally a sophisticated protective circuit monitors all the machine’s operating states.

CALA SR
CALA SR

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.

Technology

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 Control 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.
