- Page 2 A FOREWORD ABOUT D9 & TDX TECHNOLOGY™ The team at Diamond Audio never ceases to amaze me with their constant desire to develop and engineer cutting edge audio. With more than three years in research and development, I can truthfully say we have created products that I believe have no equal.
- Page 3 TDX Technology™ is to eliminate the most damaging factor to audio equipment and signal, Heat. Diamond Audio engineers decided to start with a fresh sheet of paper and build all new products that addressed all of the thermal problems and shortcomings of conventional designs while significantly raising the existing level of performance.

The D9 amplifier is an awesome component with category leading technology, proper attention must be taken during installation to ensure optimum performance.
- Page 7 Power and ground cables must be of the same gauge. If the alternator is not capable of supplying enough power for both the vehicle AND the audio system, a high output alternator should be installed for best performance. ©2005 Diamond Audio Technology. All Rights Reserved...
- Page 8 D9 amplifiers are designed to accept up to 0Êgauge power and ground cable, in some systems this may be overkill, but bigger is always better when it comes to power and ground connections. ©2005 Diamond Audio Technology. All Rights Reserved...
- Page 9 REM connection. Strip approximately 1/2Êinch of insulation from the wire. Insert the wire into the terminal, and tighten the Allen screw. D9 amplifiers will accept remote turn-on wire up to 10Êgauge or banana jacks directly. ©2005 Diamond Audio Technology. All Rights Reserved...
- Page 10 The following basic formula can be used as a quick guide to determine the total amperage draw of a mobile audio system. This formula is based on a 50% amplifier efficiency rating. Diamond Audio D9 amplifiers are actually much more efficient than that, but others may be less.
- Page 11 SPEAKER CONNECTIONS Diamond Audio recommends using speaker wire of at least 16Êgauge. Lay out the wire in the vehicle from the individual speaker locations to the amplifier(s). Observe safe wiring precautions. D9 Amplifiers will accept speaker wire up to 10Êgauge directly. Locate the speaker terminal block on the end of the amplifier.
- Page 12 This should be done with an oscilloscope, DMM, and test tone. Diamond Audio recommends that an authorized Diamond retailer with the correct equipment configures this setting. Or see Gain Setting Brief on page 16.
- Page 13 Pushing this button “IN” creates a mono signal for use with subwoofer systems. When mono mode is selected, only RCA input channel 1 is used. Leaving the button “OUT” defaults the amp to normal stereo mode. ©2005 Diamond Audio Technology. All Rights Reserved...
- Page 14 Due to the D9's high signal input and low noise performance capabilities, the gain structure should be professionally set to achieve maximum performance and lowest distortion. This should be done with an oscilloscope, DMM, and test tone. ©2005 Diamond Audio Technology. All Rights Reserved...
- Page 15 D9 800.4 Gain (cont.) Diamond Audio recommends that an authorized Diamond retailer with the correct equipment configures this setting. Or see Gain Setting Brief on page 16. +14 dB Input Select Pushing this button “IN” gives the signal inputs 14 dB of gain allowing them to see 0.2 - 4 V of signal.
- Page 16 Pushing this button “IN” creates a mono signal for use with subwoofer systems. When mono mode is selected, only RCA input channel 3 is used. Leaving the button “OUT” defaults the amp to normal stereo mode. ©2005 Diamond Audio Technology. All Rights Reserved...
- Page 17 Set the scope to see an unclipped 1 kHz sine wave from the head unit. 7. Turn the head unit volume up slowly until the sine wave on the scope starts to clip (become square at the top and bottom of the wave). ©2005 Diamond Audio Technology. All Rights Reserved...
- Page 18 If the amplifier clips with the gains all the way down, decrease the output level of the component before the amp until clipping stops. 12. Repeat step 11 for each amplifier gain in the system. ©2005 Diamond Audio Technology. All Rights Reserved...
- Page 19 If the mid and highs output is low, turn the sub gains down. Do not adjust any of the gains above the maximum undistorted output levels achieved by the procedure. ©2005 Diamond Audio Technology. All Rights Reserved...
