INSTALLATION NOTES :
1. Unpack the amplifier.
2. Mount the amplifier in the desired location in the rack. Please leave 1U rack space below and above the
amplifier for proper ventilation.
3. Connect the input and output cables to the amplifier.
4. This product is shipped with default 0 dB pad for all plug-in attenuator and equalizers.
5. Before applying power to the amplifier make sure that the forward input level to the amplifier does not exceed
20 dBmV, otherwise damage to the amplifier might occur. To be on the safe side, you should select the input
fixed attenuator to a max. value (e.g:20 dB) before powering the amplifier or preset forward path slope control
fully clockwise. Forward input pad and equalizer plug in modules are reachable under the front panel window
cover. Variable control for mid-stage equalizer is present at the front panel.
6. Ground connection is provided at the rear panel to ensure proper grounding to the amplifier.
7. Please use the power adapter supplied with the amplifier, plug the power line cord into a 115VAC/60Hz power
source.

8. After applying power to the amplifier measure the amplifier forward output level at the 30 dB output test point. If
it is very low then adjust the value of input fixed attenuator until the desired output level is reached at the
highest operating frequency. Remember that the level measured at the test point is 30 dB lower than the real
signal level.
9. Install a plug-in pad in order to activate the forward input equalization to adjust the output level to be flat across
the full bandwidth.
10. Now adjust the mid-stage forward slope and attenuator controls to achieve as close as possible to the desired
output signal level and slope.
11. Reverse gain can be set as 24dB or -2dB from the jumper settings reachable behind the front panel window.
