The Lightning bolt triangle is used to alert the user to the risk of electric shock.
1. SAFETY
1. It is important to read these instructions, and to follow them.
2. Keep this quick start guide in an accessible place.
3. Clean only with a dry cloth. Cleaning uids may a󰀨ect the equipment.
4. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
5. Do not install this equipment near any heat sources such as radiators, heating vents or other apparatus
that produces heat.
6. WARNING – THIS APPARATUS MUST BE EARTHED / GROUNDED.
7. Only power cords with the correct power connector may be used to maintain safety. Cables incorporating
the UK 13A fused plug, Schuko with earthing contacts and UL approved “grounding type” are acceptable.
These must be plugged into power outlets which provide a protective earth.
8. C10 and C14 ampliers incorporate a mains voltage switch by the power socket on the rear of the unit.
Ensure this is set accordingly to the local mains supply voltage before connecting. Failure to do so may
damage the unit and would not be covered by warranty.
9. Refer all servicing to qualied personnel. Servicing is required when the apparatus has been damaged in
any way, such as a power supply cord or plug is damaged, liquid has been spilled or objects have fallen
into the apparatus, the apparatus has been exposed to any rain or moisture, does not operate normally
or has been dropped.
10. WARNING – To reduce the risk of re or electric shock, do not expose this apparatus to rain or
moisture. The apparatus shall not be exposed to dripping or splashing and no objects lled with
liquids, such as vases, shall be placed on the apparatus.
11. Warning: Connection to a 100V line system may involve the risk of electric shock and therefore
must be carried out by an instructed or skilled person.

C Series Quick Start Guide

Dante enabled models have a dedicated RJ45 socket which acts as Input 3.
5. SETTINGS
The C Series drivers have their adjustments set in decibels (dB). A setting of 0dB equates to maximum
current or to maximum input gain. A negative value will reduce the current or input gain accordingly.
From the factory the drivers are provided with the following setting:
4. INPUTS AND OUTPUTS
The driver has two inputs labelled 1 and 2. Each
input can be separately congured to mic or line
signal level using a rear panel push switch. Global
24V phantom power can be enabled to supply
any input set to mic level. Alternatively input 2 can
accept a 100V line using a dedicated 2 pin socket.
Do not use both input 2 sockets at the same
time.
Warning: Connection to a 100V line system
may involve the risk of electric shock and
therefore must be carried out by an instructed
or skilled person.
The driver has either one or two loop outputs
labelled Loop A and Loop B. In order to achieve
correct operation it is recommended the loop and
feed resistance should be between 0.2 and 10Ω (at
DC).

2. TOOLS AND EQUIPMENT
Small hand tools including a wire stripper, small at blade and posi screwdrivers will be required.
A magnetic eld strength meter, Loopworks Measure App & R1 Reciever, or at minimum an induction loop
receiver is vital to check that the loop system is providing the desired level of performance.
3. FIRMWARE
It always recommended to ensure your amplier is on the latest rmware before installation.
On the front menu go to Driver Status > About and check the version number against the latest update
available at www.ampetronic.com/rmware-upgrades

7. NETWORK CONNECTION (OPTION)
Where tted C Series drivers feature a web interface that can be viewed in a web browser. Although
optimised for the Chrome browser, any browser can be used to view the interface. The web interface is
used to monitor and adjust the driver. You will be asked for the User Name and Password for the driver as a
deterrent to unauthorised parties. These values are case sensitive and need to be entered once per session
to access the driver.
8. TROUBLESHOOTING
The driver performs a series of diagnostics on start-up as well as constant fault monitoring once active.
Errors will show on the front screen, in the status menu and on the web interface of network enabled drivers.
Note: Some errors relate to the loop circuit rather than the amplier itself and indicate further troubleshooting
of the installation is required.
For a list of all error messages and troubleshooting see the full C-Series handbook.
If assistance is required, contact Ampetronic Support Team with a note of the exact error text.

User Name = superadmin, netadmin, audioadmin
Passwords = ampetronic (default)
For security purposes, it is recommended that the default password is changed to
a strong password at the earliest possible opportunity. This can be done using the
web interface.
Four levels of access are available:
1. superadmin - allows access to all settings
2. netadmin - access the network settings page
only
3. audioadmin - access the audio settings pages
only
4. no login - allows access to status page
6. ADDITIONAL FEATURES
• Home screen timeout – if no action is taken in a mode screen after 30s the home screen is displayed.
For a value screen the timeout is 60s.
• Sleep mode – After a 30 minute period of user or audio inactivity the driver turns on the ‘Loop outputs
disabled’ test signal and turns o󰀨 the screen to save power. The Status led ashes green to indicate this.
Any user activity or presence of audio signal brings the driver out of sleep. The inactivity time can be
changed via the website (where network option tted)
• Lock screen – A long press on the home button brings up the lock menu. This gives access to standby,
re-start (same as in settings menu) & lock. Selecting lock makes the user controls inactive. Any user
input results in a padlock being displayed. To unlock the unit press the home button six times. Unlock
instructions are shown briey when lock is selected.
• Standby – This is a user imposed sleep. Only user activity (not audio signal) brings the driver out of
standby.
