T+A PA 1100 E Integrated Amplifier

The PA 1100 E Integrated Amplifier with DAC

The PA 1100 E was developed for customers who are looking for an amplifier with various digital inputs, but who no longer need a CD drive. It was designed as a stand-alone unit and is not suitable for operation in combination with the MP 1000 E multi-source player. However, the PA 1100 E is equipped with the high-quality D/A converter of the MP 1000 E and has also been fitted with an HDMI input. When a TV is connected, the volume can be conveniently controlled via the TV remote control. All the sub-assemblies of the PA 1100 E are identical to those of the integrated amplifier PA 1000 E, and for this reason it shares exactly the same acoustic performance and characteristics. The sole difference lies in the inputs: one of the PA 1000 E’s symmetrical inputs has been replaced by a digital input board. This board operates completely autonomously from the rest of the machine, and separate voltages are fed to its digital and analogue sections. The board is fitted with its own micro-processor which assumes full control of the digital inputs, filters and converter. For this reason it has no influence of any kind on the analogue signal processing and sound qualities of the PA 1100 E. The high-quality Bluetooth® module provides music transfer from mobile devices at superb aptX™ quality.

Inputs

The digital input board enables many digital sources to be connected directly at very high quality, using either coax or optical inputs. The USB-B input even makes it possible to play very high-resolution files from a PC or via Ethernet / USB bridges such as Roon or NAA, using data rates of up to 384 kSps for PCM and up to DSD 256. The high-quality Bluetooth module provides music transfer from mobile devices at superb aptX™ quality, and the BT player can be controlled using the AVRCP protocol. A further option is the additional installation of an HDMI circuit board featuring two input and one output socket with Audio Return channel for the television set. Sound output is exclusively in stereo. The digital data are converted into analogue signals to very high standards of quality and resolution by the modern 32-bit converter. A further refinement for PCM data are two different oversampling algorithms: one of them a standard FIR filter, the other the Bezier oversampling developed by T+A, offering outstanding timing and transient handling.

Operation

The PA 1100 E can either be controlled directly on the machine itself, or using the FM 11 remote control handset supplied with the machine in conjunction with the E 2000 IR receiver. The latter can be set up anywhere close to the PA 1100 E, and connected to the RC-In socket on the back panel.
