OVERVIEW
Athens 2 is twin RIAA phono preamplifier with Dante® and AES67 network audio
outputs.
It is a mains powered device with two high quality stereo turntable preamplifiers
inputs. Each preamplifier has its own set of preset controls to allow accurate
matching of the Athens 2 input circuitary to the turntable’s cartridge. Input gain, input
impedance and input capacitance can all be set for each of the two stereo inputs.
The Athens 2 is suitable for use with both moving coil and moving magnet cartridges.
To provide the best possible equalisation of the RIAA curve the preamps feature
high quality high tolerance analogue circuitary followed by a high quality analogue to
digital converter and DSP. The combination of the analogue circuitary and DSP
provides a very good quality RIAA equalisation resulting in a very flat output.
For reliability, redundant network audio outputs are provided on two copper Neutrik
Ethercon Ethernet ports and also on two SFP slots for fibre Ethernet connectivity.
The name Athens 2 was chosen for our RIAA preamp as Dante Alighieri cites the
city of Athens as a place of good governance and mentions its contrtibution and
commitment to civil law. It is of course very important that a good RIAA preamplifier
provides perfect governance of the audio and follows the RIAA equalisation law
perfectly.

ATHENS 2 PANEL LAYOUT
Front Panel
Front Panel Features
1. Input 1 Left Channel Controls
These 12 preset dip switches provide controls to adjust the input gain, the
input impedance and the input capacitance for the left channel input of input 1.
Please see the cartridge setup section of this handbook for detailed
information.
2. Input 1 Right Channel Controls
These 12 preset dip switches provide controls to adjust the input gain, the
input impedance and the input capacitance for the right channel input of input
1.
Please see the cartridge setup section of this handbook for detailed
information.
3. Input 1 PPM
This 4 LED per channel PPM provides indication of the output level of input 1
of the Athens 2 preamplifier. The marked scale is in dBu and digital network
output levels are set such that 0dBu = -18dBFs.
If the gain is set correctly during normal use you would expect the +6 LED to
illuminate occasionally

4. Input 2 Left Channel Controls
These 12 preset dip switches provide controls to adjust the input gain, the
input impedance and the input capacitance for the left channel input of input 2.
Please see the cartridge setup section of this handbook for detailed
information.
5. Input 2 Right Channel Controls
These 12 preset dip switches provide controls to adjust the input gain, the
input impedance and the input capacitance for the right channel input of input
2.
Please see the cartridge setup section of this handbook for detailed
information.
6. Anti-Tamper Screw
The clear plastic anti-tamper shield is fitted to prevent un-authorised changes
of the Athens 2 input parameters. To gain access to the dip switches then the
Anti-Tamper screw must first be removed to allow removal of the anti-tamper
shield.
7. Input 2 PPM
This 4 LED per channel PPM provides indication of the output level of input 1
of the Athens 2 preamplifier.
The marked scale is in dBu and is digitally referenced such that on the
network outputs 0dBu = -18dBFs.
If the gain is set correctly during normal use you would expect the +6 LED to
illuminate occasionally.
If however you are using the -24dBFs output circuits then the front panel PPM
will read 6dB too high and the -6dB LED should become your lineup position.
