Page 8: Overview
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 2 Connectors These 3 connectors are the audio input circuits from the turntable. Two of the connectors are the left/ right audio circuits and these are standard RCA (sometimes called phono) connectors. The third connector is a 4mm screw terminal used for an audio ground circuit. If the attached turntable has an equivalent ground/ earth connector then the two should be connected.

Page 13: Cartridge Setup
CARTRIDGE SETUP For best results it is important to carefully setup the front panel dip switch (input channel controls) for both channels of both inputs. Most cartridge manufacturers supply information such as the recommended load impedance and the recommended load capacitance. The Athens 2’s input should be set to match these recommended figures. -
Page 14: Gain Settings
Gain Settings NOTE: Please set input impedance and input capacitance prior to setting the gain. NOTE: Only 1 gain dip switch should be on at any time for gain settings. The quick and simple way of setting the gain is to connect your turntable and play a record then adjust the gain dip switches such that the PPM only ever occasionally peaks at +6. -
Page 15: Input Impedance Settings
Input Impedance Settings Most cartridge manufacturers provide the recommended load impedance for their cartridges. The Athens 2’s inputs should be set to match this recommended figure as closely as possible. 4 dip switches adjust the input impedance and more than one dip switch can be turned on at the same time. -
Page 16: Input Capacitance Settings
Input Capacitance Settings If you’re using a Moving Magnet cartridge then the manufacturer will provide the recommended load capacitance. The Athens 2’s inputs should be set to match this recommended figure as closely as possible. If you’re using a Moving Coil cartridge then the input capacitance should be set to minimum (15 pF (all capacitance dipswitches off)) 4 dip switches adjust the input capacitance and more than one dip switch can be turned on at the same time. -
Page 17: Network Dbfs Levels
NETWORK dBFs LEVELS The Athens 2 provides 2 separate stereo network audio outputs for each of the 2 input preamplifiers. One of these stereo outputs references 0dBu = - 18dBFs The other of these stereo outputs references 0dBu = -24dBFs Please note the front panel PPM is set for 0dBu = -18dBFs and if you are working in an environment utilising 0dBu = -24dBFs then the PPM will read too high and the -6dB LED will actually represent 0dB. -
Page 18: Connecting The Athens 2 To A Dante® Network
CONNECTING THE ATHENS 2 TO A DANTE® NETWORK The Athens 2 is a network audio devices utilizing the reliable and versatile Dante® audio over IP protocol. Dante® is a proprietary system (although very widely used) the originators of which are Audinate. The information below is only meant as a very basic guide. -

Page 20: Device Not Showing Up In Dante Controller
Device Not Showing Up In Dante Controller ® ® If your Dante device does not show up in Dante Controller then the most likely issue is that the device’s IP Address is not appropriate for your network. A) It maybe that the device is set to obtain an IP address automatically using DHCP (this is the default configuration) and your network is setup for fixed IP addresses only and does not have a DHCP server. -
Page 21: Aes67 Mode
AES67 and therefore the Athens 2 can be set to AES67 mode for interaction with other AES67 devices. Please note however that Glensound are relying on Audinate’s AES67 interface and are unfortunately not able to provide full AES67 support for the unit. AES67 support should be sought directly from Audinate. - Page 22 2. Sending AES67 Audio To transmit AES67 audio to the network a multicast flow must first be setup. This is done by selecting the ‘Create New Multicast Flow’ Icon in the Device View. Tick the AES67 Flow check box, then select up to 4 channels to be included in the flow then click ‘Create’...

Page 28: Updating The Brooklyn Chipset
UPDATING THE BROOKLYN CHIPSET The Brooklyn module is a device supplied by Audinate that does most of the processing for the actual Dante/ AES67 network audio streams. There is one Brooklyn module in each Athens 2. We supply special code (a .dnt file) that sets up/ initiates the Brooklyn module and makes it work in particular way that is compatible to the Athens 2. -

SPECIFICATIONS RIAA EQUALISATION The Athens 2 uses a hybrid of Analogue & DSP circuits to perform its RIAA equalisation. In the below graph two horizontal light blue/ purple lines show the frequency output of the two channels of the amplifier after the RIAA equalisation. The level reference is the right Y axis (right hand scale) and the frequency range is the X (bottom) axis. -
