I recently got a Pioneer DEH-5250SD HU. Bass reponse is too good and there are hell a lot of controls to tune low frequency sounds based on the users taste. But very unfortunatly , the 5 Band EQ system is able to control only till 8K at higher end of frequency. I am not able to get the same quality of sound at higher frequenzies like the way I used to get from my previous HU DEH-4750 which had just a 3 band EQ support with ability to set Q factor. Sounds close to 8k frequency dominates well over sounds over 10K in 5250SD. My personal taste is to boost more of sound over 10K frequency and to reduce frequencies between 3-8K, offcourse with ample amount of mid and low frequencies.Would any of you know whether it is possible to customise EQ curve inorder to shift the higher band of frequency more towards 10-12.5K range ? OR simply is there a way to improve the treble response over 8K frequency ? I believe adding an amp would not solve the issue since the source itself provides weak signals on band of frequency over 8K
I have tried the so called 'Advanced Sound Retrival system' with its two possible levels ...but it makes only a little difference
Please note that when I say out put at higher frequency band is poor in the new unit, it is based on my experience in using an older model with same speaker set, same vehicle and same song !!
Many thanks in advance !!
