Telos ZephyrExpress user manual Send Mixer, Routing

to feed a local PA system or DAT recorder, along with a rear-panel stereo headphone jack. The other monitor mixer has dual stereo headphone outputs to feed producer and talent simultaneously.

If we sound proud of the design of ZephyrExpress’ mixers, we are. But if you’d prefer to bypass them entirely, there are also separate direct-codec outputs . You can use these for high-quality stereo monitoring regardless of the mixer settings.

?The XLR inputs are differentially balanced, with pin 2 hot. Input impedance is 1k½ per leg, or 2k½ balanced, to match most professional microphones. The phantom power supply provides 48vdc at 6 mA per microphone.PHANTOM POWER...provides DC to charge a condenser microphone and power its preamplifier on

the same 2-conductor balanced shielded cable thatÕs carrying the micÕs audio. It does this by applying the voltage equally to both signal wires, returning the voltage through the cableÕs shield. Since audio is carried differentially in a balanced wiring scheme, the two donÕt interfere: there is no DC voltage from one signal wire to the other.

ItÕs called ÒPhantomÓ because a properly-wired dynamic or ribbon microphone wonÕt see the voltage at all.
