Congratulations Congratulations! You have just acquired one of the best-ever preamplifiers. The MELODY was created by an engineering team with more than 60 years’ experience designing world-class products for the professional audio, national security and military businesses. Ever since its creation in 1951, Nagra builds devices that offer exceptional sonic performance.
In order to protect against the risks of fire and electric shock, please keep this device away from rain and humidity, use exclusively indoors. The Nagra MELODY must rest on a stable support. We recommend that you use the anti-vibration support, Nagra VFS, Vibration Free Support, developed by Nagra consisting of isolated massive aluminum plates using the same silicon base damping material as the Nagra CD mechanics.
10. IR window and remote LED *In standby mode the power consumption is less than 10 mW. Please note that when turned ON, the MELODY will go through a 10 second pre- heating phase. This is in order to optimize the warming-up of critical components.
You may then push the mains switch into the I position. Connecting an optional external power supply The Nagra Melody can also be powered by an external source like ACPS compact power supply or full frame units like the Nagra MPS.

MELODY. The BYPASS is active when the MELODY is turned OFF, whether it is actually connected to a power source or not. The BYPASS input will directly be connected to the XLR output (output 1).
Gain selection In order to accommodate a wide range of amplifier/speaker combinations, the MELODY’s internal gain can be adjusted by a toggle switch on the front panel. The gain can be changed while the unit is ON and playing. 12 dB amplification is a 4x multiplication, so be aware of the sound level when you change gain.
0 position is for Philips RC 5 format – for Nagra RCU III remote control 1 to 6 is to use Nagra RCU and RCU II device number, simply turn the selector to the number you wish the Melody to respond to.
Phono input settings (optional) This option may be purchased and installed at Nagra factory, or you can have it installed later on by your dealer. With the optional phono module, Input A becomes the phono input. Simply connect your turntable to the input A and use the ground connector on the left.
