T A R-Series Phono Module User Manual
Welcome
We are delighted that you have decided to purchase a product. With the
phono-module PHE-PA R for your R-Series (2000) amplifier you have acquired a
top-quality piece of equipment which has been designed and developed with the
wishes of discerning listeners as absolute top priority.
This system represents our very best efforts at designing practical electronic
equipment incorporating solid quality, user-friendly operation and a
specification and performance which leaves nothing to be desired.
All these factors contribute to a piece of equipment which will satisfy your
highest demands and your most searching requirements for a period of many
years. All the components we use meet the German and European safety norms and
standards which are currently valid. All the materials we use are subject to
painstaking quality monitoring.
At all stages of production we avoid the use of substances which are
environmentally unsound or potentially hazardous to health, such as chlorine-
based cleaning agents and CFCs.
We also aim to avoid the use of plastics in general, and PVC in particular, in
the design of our products. Instead we rely upon metals and other non-
hazardous materials; metal components are ideal for recycling, and also
provide effective electrical screening.
Our range of accessories includes high-quality cables and connectors.
We would like to take this opportunity to thank you for the faith you have
shown in our company by purchasing this product, and wish you many hours of
enjoyment and sheer listening pleasure.

Preamble
Caution:
Installation and de-installation of the Phono Preamplifier module must be
carried out by T+A or one of our authorized dealers.
The installation procedure is described in detail in service note
“S0122_PHE_PA_R_Installation“.
For any kind of damage caused by improper installation, T+A elektroakustik GmbH & Co. KG accepts no liability.
Adjustments
To achieve the highest possible audio quality the Phono Preamplifier must be carefully adjusted to match the requirements of your cartridge. The Phono modules employ 4 selector switches (two for the right, two for the left channel) to adjust the input sensitivity and the input impedance precisely.
All settings are described in detail in chapter „Operation“.
Connections
The connection of a turntable to the PA 2000 R / PA 2500 R / R 2500 R is shown on page 26. Please make sure to connect the additional grounding lead of your turntable to avoid hum and noise.
Operation
Please turn down the volume to a low level and then select „Phono“ as listening source. Start playback of a record and adjust the volume to the desired level.
General Settings
Adjustments
Accurate matching is crucially important to the sound quality produced by a pick-up system. For this reason the phono module features a set of rotary switches which enable the user to adjust it perfectly to suit all current pick-up systems.
The rotary switches can be turned to a desired position using a small screwdriver. The arrowhead on the switch points to the selected switch position (on the figure below = position ‘4’ ).
The input sensitivity, capacitance and impedance should be adjusted as shown in Tables 1 to 4.

Adjust the input sensitivity (Gain)
The rotary switches on the left hand side are used to set the desired input sensitivity for the left and right channels as shown in Table 1. The input sensitivity can be adjusted in 8 steps with and 8 steps without subsonic filter. The information about the requirements of your cartridge will be included in the manufacturer’s specification for the pick-up system you intend to use. Select the value which is closest to the manufacturer’s stated figure. If you do not have access to the manufacturer’s specification, a good starting point for sensitivity is position 2 or A (4,0 – 6,5 mV). This is the factory default setting.
It is essential to set the same value for both channels.
The subsonic filter attenuated rumble and low frequency noise below the hearing band. This helps to avoid excessive excursions of the woofers. To switch on the subsonic filter, please select one of the input sensitivities from the table column marked ‘Subsonic on’ (8…F).
