Installation and Connection

1. 

Before placing the device into its operating location, consider the following:

 

The device’s ventilation outlets should not be obstructed by other devices and objects and 

enough space for air circulation should be provided.

 

The device should not be placed next to any heat-sensitive piece of equipment. (The 

surface of ISOCHRONE 10M may reach a temperature of 55°C (140°F) during operation.)

 

To minimize frequency instabilities, the device should not be placed near equipment 

generating strong magnetic fields, such as generators, transformers, etc.

 

To prevent possible interference, observe a minimum distance of 5 centimeters (2 inches) 

between the cables of this device and any non-coaxial audio cables.

 

It is OK to use the device unmounted (i.e. not in a rack) as long as the above conditions are 

met. There is no requirement for the device to be leveled horizontally.

2.  If the DC Power Connection (7) is to be used, make sure the power cord is wired properly, 

because reversed polarity may damage the device. Refer to the illustration and the table 

below for information on how to make the connection. If in doubt consult a competent 

echnician.

If the mark on the Speakon NL4FX plug is…

connect to the following mark on the power 

supply unit circuit board / terminal:

2-

1-

Earth

(

optional, use it if available On the power supply unit

)

3.  Mount the device on its operating place in the rack and secure it with the screws.

4.  Connect the AC Power Connection (6) and/or the DC Power Connection (7) to the respective 

power outlet(s).

5.  Connect the devices you would like clocked to the Atomic Clock Outputs 1-8 (8) on the rear 

panel. (These devices must support 10 MHz atomic clock signal input.)

Note:

 When connecting the devices, do so with the studio volume turned down. Some devices may 

emit unpleasant sound until properly configured to accept incoming clock.

Operation

1.  Power the device on by depressing the Power Switch (1) on the front panel. Depending 

on the connected power sources, the Power Supply Indicator(s) (2) and/or (3) will go up.

2.  If the connected slave devices are off, power them on.

3.  Make sure the atomic clock indicators of the slave devices show that the 10 Mz clocking 

signal is received properly. Some devices will automatically synch to the incoming clock 

from the ISOCHRONE 10M when connected; others may require additional configuration in 

order to utilize 10 MHz clock.
