How to Operate the OC818:

The OC818 requires phantom power, so please make sure that you are supplying it according to P48

(48V +/- 4V). Peak current consumption is below 4 mA (OC818 with OCR8 connected). Almost all

state-of-the-art professional mixing consoles, preamps and audio interfaces provide enough power,

however some battery driven, or older devices may fail to do so!

Setting up the OC818:

For optimum performance, do not cover the grill of the OC818, and always ensure a secure fit in the

OCH8 (holder) or OCS8 (suspension).

Always place your sound source to face our beautiful logo!

If you record in figure-8, then you can also use the rear side. Or if you record in Omnidirectional, then

it does not matter at all. Or if you pick up a Leslie cabinet and are experimenting with the phase-

shifting-effects. But otherwise: Please face the logo!

Adjusting the Polar Pattern:

The OC818 provides 4 default directional characteristics: figure-8, supercardioid, cardioid and

omnidirectional. The 5

you can program your custom pattern to this position. Factory setting (before you change the

pattern by an OCR8) for this position is broad-cardioid without High Pass Filter and Pad Switch –

those are inactive in Preset Mode.

Switch the polar pattern selector to the desired pattern. Please note that the microphone needs a

few seconds to adapt to the new pattern, especially if you switch all the way from figure-8 (left) to

omni (right) or vice versa (this gives any sluggish electrons time to catch up).

High Pass Filter:

The high pass filter is a powerful tool to reduce unwanted low frequencies, like stage noise, handling,

or your Uncle Albert's singing.

''0'' means not active

''40'' is a high pass 2

''80'' is a high pass 2

''160'' is a high pass 1

Pad Switch:

The Pad switch reduces the sensitivity of the microphone and prevents overloading the microphone

in loud environments.

''0'' means not active

''-10'' means that the microphone is 10 dB less sensitive

''-20'' means that the microphone is 20 dB less sensitive

''-30'' means you may need to see an optician, as there is no "-30" position.

Note: The -10dB position reduces the bias voltage of the capsule, so the microphone can take 10dB

more input (I am looking at you there, trombone jockey), whereas the -20db Setting reduces the gain

by another 10 dB to protect your mixer preamp from overload.
