instructions.
The Lightning bolt triangle is used to alert the user to the risk of electric
shock.
SAFETY
- It is important to read these instructions, and to follow them.
- Keep this quick start guide in an accessible place.
- Clean only with a dry cloth. Cleaning fluids may affect the equipment.
- Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
- Do not install this equipment near any heat sources such as radiators, heating vents or other apparatus that produces heat.
- WARNING THIS APPARATUS MUST BE EARTHED / GROUNDED.
- 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.
- Refer all servicing to qualified 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.
- WARNING To reduce the risk of fire 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 filled with liquids, such as vases, shall be placed on the apparatus.
- 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.
TO PREVENT ELECTRIC SHOCK DO NOT REMOVE THE COVER. THERE ARE NO USER- SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL
TOOLS AND EQUIPMENT
Small hand tools including a wire stripper, small flat blade, and posi screwdrivers will be required.
A magnetic field strength meter, Loop works 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.
INPUTS AND OUTPUTS
The driver has two inputs labeled 1 and 2. Each input can be separately
configured 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).
Do not run input and output cables close together
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:
- Current: -20dB from full output
- Driver Name blank – reports model number
- Metal Loss Compensation (MLC) OFF
- Phase Shift ON
- Input Gain Channel 1 -80.0dB
- Ethernet Parameters Set by DHCP
- Input Gain Channel 2 -80.0dB
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 off the screen to save power. The Status led flashes 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 fitted)
- 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 briefly when lock is selected.
- Standby - This is a user-imposed sleep. Only user activity (not audio signal) brings the driver out of standby.
NETWORK CONNECTION (OPTION)
Where fitted C Series drivers feature a web interface that can be viewed in a web browser. Although optimized 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 unauthorized parties. These values are case-sensitive and need to be entered once per session to access the driver.
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:
- superadmin – allows access to all settings
- netadmin – access the network settings page only
- audioadmin – access the audio settings pages only
- no login – allows access to status page
TROUBLESHOOTING
OUTPUT A / B OPEN CIRCUIT: The driver has detected that the loop connected to A / B out is too high impedance.
HEATSINK TOO HOT PLS SWITCH OFF: The driver heatsink has reached a critical temperature and the driver must be switched off.
The following error messages all indicate an error in the internal circuitry
of the driver. Please contact Ampetronic technical support if any of these
errors are seen, quoting the error message text.
OUT A / B IDLE OVERCURRENT
OUT A / B FUNC TEST HIGH OVERCURRENT
OUT A / B FUNC TEST LOOPS CROSSWORD
These error messages indicate a possible error with the loop or the connections to the loop:
LOOP A / B R < 200mR FIX AND RESTART: The driver measured < 200mR for the loop impedance. This is too low for the driver and must be fixed before the driver will finish the start-up diagnostics. Switch off, fix the fault and switch on again.
LOOP A / B > 10R LOOP COULD CLIP: The loop is not open circuit but has a resistance of > 10R. This is too high and the driver will clip on output peaks. This is a warning and the driver will continue after 5 seconds.
CHANNEL A / B OPEN CIRCUIT: This message is displayed if the loop is disconnected whilst the driver is operating (e.g. if a carpet fitter cuts the loop). The message is displayed on the front panel for 5 seconds and on the web interface.
These are information messages and do not indicate an error:
DIAGNOSTICS IN PROGRESS: This message is displayed on the front panel
whilst the start-up tests are being performed.
New IP (DHCP) XXX.XXX.XXX.XXX A new Ethernet address has been assigned to
the driver. This can occur when an Ethernet cable is plugged into the driver
or the DHCP server re-assigns a new IP address.
These messages appear in the status menu when the associated error is present:
Power Limit – derated: The driver is overloaded and the drive current has
been reduced
Loop A open circuit: The driver has detected an open circuit on loop A.
Loop B open circuit: The driver has detected an open circuit on loop B.
Temp Limit – derated: The internal heatsink is too hot and the driver
current on both channels has been reduced.
Temp Limit – muted: The internal heat sink has reached an unacceptable
level and outputs have been turned off.
Channel A Clipping: The driver output maximum voltage is being exceeded
and the loop A signal is being clipped.
Channel B Clipping: The driver output maximum voltage is being exceeded
and the loop B signal is being clipped.
