5.1 USB port

The USB port is not a digital audio input. It is dedicated to upgrading the firmware of the P10. Do not use
it for any other purposes. For more information please refer to the firmware update instructions in the
dedicated chapter of this manual.

5.2 Ethernet port

The Ethernet port is used for two closely related functions.
Connection to a local network router allows control of the P10, its functions and configuration through the CH
Control App, loaded on an Android device.
In True Monaural configuration (standard or extended) the connection to an Ethernet network allows the two
separate audio chassis to communicate in a Master/Client relationship, so that control settings track each
other. One unit should be set as 'Master' and the other as 'Client', in the 'Network / Role' menu.
In a situation where a four–chassis P10 is not connected to a network, an RJ45 Mirror lead (NOT a standard
RJ45 lead) connected between the two audio units will allow control synchronicity. In this case, select 'Direct-
Link' in the 'Network / IP Settings' menu of both audio units.

5.3 Local area network considerations

We recommend that you construct a dedicated local network for both system control functions and music
streaming. It can be operated from locally located network switches, galvanically isolated from your
main household network using affordable and readily available optical converters. This will improve the
responsiveness of your setup, and keep as much high frequency noise out of your audio system's ground
plane as possible.

5.4 Ground lift

The grounding switch allows owners to combine or separate the signal and chassis ground. In any audio
system, it is generally best to combine the signal and chassis grounds at one point only, usually in the
preamplifier, in order to break ground loops and kill potential hum.

5.5 Inputs

Make sure that the P10 is switched off and disconnected from the wall socket.
Connect each set of tonearm leads to the input you have chosen. On a Dual Monaural P10 the left inputs are
the top sockets and the right inputs are the lower ones. In a four-chassis, True Monaural (or True Monaural
Extended) set up, you will connect the left inputs to one chassis and the right inputs to the other. You have
four sets of inputs (and twice as many in the four- chassis, Extended configuration).
The 4mm banana plug with a butterfly nut allows for multiple ground connections. It can be removed from
the rear of the P10 for easier connection of multiple grounds and selection of the grounding point (chassis or
signal ground).
