This works because while the voltage on the cold line is ground, the current in it is not. Matching the impedance as noted helps ensure that noise present is the same on both hot and cold so that the differential receiver can cancel it.
Recall that when we say it's a balanced circuit we mean that the impedances are balanced, not the voltages. Our proprietary design gives emergency specialists, firefighters and caregivers of any type an easy and versatile way to lift difficult to move patients. Batter operation (three 9V with 12 hour battery life) and carry strap for maximum portability. Samson Strap is the revolutionary, ergonomic and above all safe way to lift and transfer injured and disabled people. Two mic/line inputs and 1 stereo input (4 channels total). To be pedantic for the kids playing along at home - the resistor to ground in the impedance-balanced output is matched to a series buildout resistor after the driver. Features: An incredibly compact 4-channel mixer with exceptional sound and a wide range of professional features. The interface is still balanced, they just hang a resistor off the other line instead of another amplifier.Īhh - I suppose that's true - you still get to subtract the noise from the resistor side, even though there's no signal to add. For a mixer this size it's probably meaningless, the difference between +18dBu and +24dBu at the far end is unimportant. What you lose is 6dB of signal driving capability, since only one line is being driven.
If you have the fake-o balanced outs, you lose some noise immunity if you're driving long lines.
Samson MixPad MXP124FX - Compact, 12-Input Analog Stereo Mixer with. I think the main place you can get bitten is if they have "impedance balanced outputs" instead of full differential outputs. They feature low-profile molded enclosures for an ergonomic fit and up to 40 dB of.
