Hi Steve, (1) Thanks for the quick advice and yes, I did get the DD-1 very soon after my order. (2) I am quite sure I went thru' the manual but it may be due to my poor understanding as this is the first time I am trying to do gain matching outside my installers' shops, hence the idea of getting the DD-1. I do understand your instructions and comments but the question remains that even at full range with cross over bypassed, the frequency of 1k Hz used somehow does NOT seems complete as I mentioned that: a) Physic class taught me that impedence which I believe will affect gain matching DOES depends of frequency used . Gain at 1k was set with no clipping as well as with tones below that from 300, 400, 500kHz etc. from my own CD did not indicate but it did show some clipping at 1.25kHz or something like that which raised my concern if it would not clip at other frequencies although it did not at 1kHz. 3) Also, I do not understand why the manual reference to track# 6 of -15db@ on setting for full range amp for louder system since there is very high chance of clipping if we all agree that typical CD is at -5db and how then we know that it is really clipping the amp. Thanks again amd looking forware to your continued help. Richard 6. Play track 4 or 6 on test CD (Track 4 will ensure maximum sound quality, Track 6 will result in a louder system). Your choice.

Hi There, Doesn't impedence change at different frequencies and if yes, test tone of just 1k means that it is only good for gain matching at around 1k tone for my midrange amp and that I cannot use for detection of clipping for the other 2 amps designated for tweeters crossed at 2.8kHz and above or for the midbass cross below 500Hz ? I vaguely remembered that with handheld scope, I had seen that an amp may not clipped at some frequencies for gain set but cipped at others i.e. even not usable for midrange amp ???? Not sure how to proceed to use the newly received DD-1 to gain match my Front 3-way setup with 3 2-channel amps .... Anyone, please help to advise. Thanks. Richard@SIngapore

Just got mine too since the promo code works now but some clarification here from Steve or notification after my PM would have been polite to customers ? Nevertheless, looking forward to receipt and working with it ! Tks ...

Any clarification on the promo code that reports being invalid ?? Tks ...

No indication to inform potential buyers that promo code is over and they would remain confused !! Hope this get resolved or clarified soon !!

Same here .. tried the coupon code at http://www.wccaraudio.com/ and it said invalid. PMed Steve 2 days ago and still waiting for some advice which I hope comes soon.
