Page 4: Basic Information
Protection circuitry against overheat and short circuit is on board to protect Your equipment in an optimal way. The power amplifier of the EVOLUTION C1/ R1 uses two output stages and two power supplies. One output stage is working from a low voltage supply when only low power is demanded. During this time the other output stage is also working, but doesn’t deliver current to the speaker (and therefore produces no heat). -

1.5 CD player / D/A- converter The EVOLUTION C1 is equipped with upsampling circuitry and highly precise a/d converters. The theory of function will be described in the following text. If You are not interested in technical details, skip these chapters and simply listen to the music coming from the C1. -
Page 6: Filtering
1.5.3 Filtering If a digital signal is converted to analogue the analogue signal contains not only the original signal, but as well it’s mirror image which lies in the frequency domain beyond one half of the sampling frequency. This mirror image (aliasing) can cause unwanted interference with the original signal and thus must be filtered out before passing the signal to the amplifier. -

Page 13: Loudness
4.13 Loudness If You listen to music at low levels, You often recognize that bass and treble reproduction are weak. This is because the human ear is not sensitive to bass and treble at low sound levels. To compensate this You can use the parametric loudness function of the C1 / R1. -
Page 14: Remote Control
5. Remote control There are two different models of remote controls available for the C1 / R1: AVM RC1 and the programmable AVM RC2. All the main functions of the C1 / R1 can be controlled. The following scetch shows the functions of RC1... -
Page 15: Cleaning
6. Cleaning Use a soft cloth and normal glass cleansing fluid. CAUTION: Make sure that no fluid comes into the unit. Do not use scouring cleaners. They may damage the surface. 7. If something doesn’t work..Some putative defects are often caused by mistakes in operation. Sometimes other units connected to the amplifier can cause problems. -
