Telos ZephyrExpress user manual Console at your fingertips, Mix flexibility

A console at your fingertips...

ZephyrExpress includes three separate 4-input stereo mixers, designed to make remote broadcasting easier. They incorporate both digital and analog technology, giving you the best of both worlds.

We used sophisticated analog circuits for:

•Wide input range

•Smooth limiting, with the ability to handle sudden peaks without digital artifacts

•Uncompromised audio specs

•Field-worthy reliability

But we control these circuits digitally, for:

•Versatility

•Fast, repeatable setups

•The ability to store presets for different sites

•The ability to lock critical settings against accidental tampering Audio quality matches the highest standards:

•Frequency response +0, -0.1dB between 20Hz - 20kHz

•Total harmonic distortion < 0.019% @ 10dB, 20Hz - 20kHz

•Dynamic range of +94dB, 20Hz - 20kHz

Mix flexibility

ZephyrExpress’ SEND mixer can control two microphones — each with switchable sensitivity, limiting, and low-cut filters — and either two mono or one stereo line-level devices. The line inputs accommodate professional or consumer-level sources, balanced or unbalanced, on XLR or 1/4" plugs. The microphone inputs can be switched to use as one or two additional balanced line-level inputs, or to use as test oscillators. All of the inputs have flexible routing and muting switches.

ZephyrExpress has two separate MONITOR mixers, for ultimate flexibility when setting up remote broadcasts. You can send local mics down the ISDN line, while mixing them with high-quality music received over ISDN for a house PA system... at the same time monitoring distant studio cues along with the rest of the mix in a producer’s headphones. You can even carry a mic out into the audience, while all this is going on, and control its mono feed to the local PA system without affecting the ISDN transmission.

Each monitor mixer has routing, pan, and level controls for the two send channels and for the two receive channels. Stereo panning can be set to switch automatically depending on how a signal is routed. One monitor mixer features XLR balanced outputs
