Introduction
Our Symphonic phono stage brings advanced features and our proprietary technology to vinyl, enabling the easy integration of turntables into any system as our flagship MC phono stage.Before the operation, we strongly advise you to read this user manual thoroughly.We also recommend that you store this user manual, along with your original receipt of purchase, in a safe place should you require assistance in the future.
Protection against liquids & heat
- Symphonic is not protected against liquids of any kind.
- Never place containers of liquid on Symphonic. Never allow Symphonic to come into contact with moisture or liquids; doing so could result in electrocution or damage to the Symphonic’s internal circuitry.
- Be aware that liquids, including water that has dried, can leave minerals that can affect the PCB and other components, which could eventually lead to oxidization and short-circuiting.
- If the Symphonic comes into contact with moisture or liquids, immediately disconnect from the mains power supply, and connected equipment, and contact Chord Electronics for further advice.
- Never operate the Symphonic near sources of heat or naked flames as this will decrease the lifespan of the internal components.It is advised that you do not operate the Symphonic in an area of direct sunlight or on top of significant heat-producing devices.
- Please be aware that it is entirely normal for the Symphonic to become warm during use, particularly within a stacked configuration. If you are concerned about the temperatures, please switch the device off or consider a different placement.
Dismantling & radio frequency interference
- There are no user-serviceable components within the Symphonic or its power supply. Dangerous voltages/currents exist within the Symphonic and its power supply, posing a severe risk of electrocution and/or fire.
- Never attempt to open, dismantle or apply internal third-party devices to it or insert anything other than the listed interconnects or headphone adapters within this user manual.
- If the Symphonic develops a fault or the casework becomes damaged, immediately disconnect from the mains power supply and connected equipment, and contact Chord Electronics for further advice.
- With a thick, solid aluminium chassis, Symphonic’s casework largely protects the sensitive internal circuitry from radio frequency interference. However, for optimal performance, it is recommended that the following points are observed:
- Consider placing the Symphonic away from wireless routers.
- Separate the Symphonic from amplifiers using toroidal transformers.
- Operate mobile phones at a distance to avoid interference.
Connecting your equipment
- Before connecting the Symphonic to any equipment, consult the manufacturer’s user guide to confirm compatibility.
- When connecting the Symphonic to any equipment, make sure that all devices are off, including the Symphonic.
- Once connected, switch all equipment on starting with the source and ending with the amplification.
- Initially, operate any of the connected equipment on its lowest gain setting and lowest volume setting, gently increasing to a comfortable listening level.
- Never operate connected equipment to the Symphonic at excessive sound levels; permanent hearing damage and loss can occur.
- The included 10 amp IEC mains lead plugs into the Symphonic.

Getting to know Symphonic
Nestling in the Choral range, the Symphonic is our flagship MC phono stage. The high-performance Symphonic uses our latest high-frequency power supply technology to exploit vinyl’s full potential, along with many key features, to brings the performance levels in line with the Choral range, home of the DAVE DAC/preamp.The Symphonic offers a number of input impedance and gain options as well as balanced and unbalanced input options, making it a highly flexible device for integrating high-quality turntables into Chord systems.
To get the very best from the device we recommend that you familiarise yourself with the user manual.
The top panel
The top panel has no user-configurable options. Instead, there are 2 viewing portals. This is where you will see the LED changes when pressing the buttons on the back of the unit.
The rear panel
The rear panel has 1 x pair of RCA and 1 x pair of XLR switchable inputs, also, 1 x pair of RCA and 1 x pair of XLR outputs. There are 12 dip switches to help set Symphonic to your requirements. Read section 5 for more on about Symphonics buttons.When installing any cable, you must make sure they are securely in place.
Setting up Symphonic
Whilst the Symphonic operates normally within a stack of Chord Electronics Ensemble stands along with units such as the DAVE and Etude, it is recommended that you allow the device to breathe. Allocating 10cm of space around it to convection-cool during operation is advised. If possible, do not place the unit(s) inside an inadequately ventilated cabinet.
Connecting an input to Symphonic
In order to connect up Symphonic to a source, you must connect the cables from your turntable to one of the inputs listed below. Symphonic has 2 pairs of inputs, one set of balanced XLRs and one set of unbalanced RCA inputs. to begin, as you look from the front;
- First, you must ensure that Symphonic, and any connecting equipment, is turned off.
- Select the correct outputs from your turntable device and insert the cables into the ports.
- Ensure that you pay attention to the left and right channels for your device. The left output from your turntable must go into the left input of Symphonic and the same for the right channel.
- Connect your ground cable to the ground pin securely
Connecting Symphonic to a pre amplifier
Using The XLR and RCA outputs shown below, it is simple to connect the Symphonic to a pre amplifer. Left channel connections are on the left, right channel connections are on the right, each output is identical. to begin, as you look from he front;
- Ensure all your devices are still turned off.
- Locate the XLR or RCA outputs shown below on the Symphonic and connect to the XLR or RCA input on the choosen pre amplifier.
