SONY ECM-778 (01) PDF DOCUMENT

The SONY ECM-778 is not dust-proof, splash-proof, or waterproof.

To avoid the risk of a fire or an electric shock, observe the following:

• Do not disassemble or alter this unit.

• Do not use this unit with wet hands.

• Do not allow ingress of water or foreign matters (metal, flammable substances, etc.) to this unit.

• Do not use this unit in a place subject to water splashes, high humidity, dust, oil fumes, and steam.

To avoid the risk of damage or a malfunction, observe the following:

• The SONY ECM-778 is precision equipment. Do not drop the unit, hit it, or subject it to a strong physical impact.

• Do not subject this unit to mechanical shock such as crushing, bending, puncturing or shredding.

• Do not use or store this unit in a place subject to high temperatures and humidity.

• When using this unit outdoors, keep the unit from exposure to rain or seawater.

Handle this unit with care to avoid the risk of dropping it or letting it get exposed to liquid.

Always hold the plug when disconnecting. Pulling the microphone cable may cause it to snap.

The microphone holder is used when attaching your SONY ECM-778 to a microphone stand (sold separately). If the microphone holder cannot be attached directly to the microphone stand, attach the stand adaptor (SAD-34/SAD-35) to the microphone holder.

If wind noise or breath noise is noticeable with your SONY ECM-778, attach the wind screen.

If strong wind noise persists even with the foam wind screen, use the fur wind screen instead.

The microphone spacer is used when attaching the SONY ECM-778 to a camcorder microphone holder (sold separately) or a similar device. If you still notice vibrations after attaching the microphone spacer (molded type) to the unit, use the microphone spacer (sheet type) instead. To do this, remove the two release sheets and wrap it directly around the unit.

Slide the LOW CUT switch on your SONY ECM-778 to “ON” to cut low-frequency sounds and reduce noise.

The SONY ECM-778 is for use with an external power supply only. Connect the microphone output of the unit to the microphone input of an external power source (such as an AC power supply, an audio mixer, or a camcorder). For the connection, use the microphone cable.

Note: Before connecting this unit to an external device, ensure that the device has a microphone input compatible with 44 V to 52 V. Unbalanced cables cannot be used with this unit. Always use a balanced cable.
