Nikongod, I changed electrolytics to 5600uF improving the phase distortion in low frequencies
Well, I did some research ...
both p and s drivers himself has impedance of 5 ohms. Added to this the cable (2 Ohms) and a resistor...
Thanks Erik by the suggestion. It is one very good project but I search something simpler with the expense of losing some audio quality. Even because most equipament that I am going to connect to that are not high fidelity.
Only shown single channel.
At least simulating in spice it works. In the 1.7v led voltage occurs a hard clip but
this is already a lot for the ER4P then the resistor is a voltage divider.Both eletrolitics act like a single...
Recently I bought an etymotic ER4P and would like to build a protection circuit to be able to use with generic equipament tv,radio... Should protect against DC-offset, transients and to transform the P for S because the phone is already...
OK I discovered what happened. This Panasonic has one more terminal in plug for the remote control that works through resistance variation. what I did not know is that the signal that is constantly applied by cdp also has return by the...
Thanks Tangent. The phone continues working but I am afraid of have changed the sound. If this happened, I never am to to know because here in Brazil I do not have opportunity of testing and to compare good phones. HD280 I imported and...
Hi all
I need help here. I had just bought a HD280 and when I connected he in Panasonic SL-SX420 and without turn on I started to hear some cracks in continued time's intervals. Being worried I decided measure DC offset with a simple...
