The X-8S was discontinued in November 2016.
It is available only as a special order with eight to twelve week delivery; please inquire.
The X-8S is a multipattern condenser microphone with three polar patterns selectable via switch:
- left switch position – omnidirectional, indicated by blind hole mark;
- center switch position – bidirectional, indicated by two blind hole marks;
- right switch position – cardioid, without mark.
The X-8S multipattern condenser microphone generates variable polar patterns via two 14mm cardioid capsules oriented at 180 degrees. In bidirectional mode, the “front” capsule (marked with a blind hole) is routed to pin 3 of the XLR output, and the unmarked capsule is routed to pin 2 of the XLR output. The capsule outputs are reverse polarity, such that when connected to a standard XLR microphone input amplifier, the signal from the marked capsule will have positive polarity. In cardioid and omnidirectional mode signal is present only on pin 3, with pin 2 providing an impedance-balanced output. The capsule with blind hole mark is active in cardioid operation.
The standard output X-8S does not sum the opposing signals from its two capsules internally in bidirectional mode, so a balanced input microphone amplifier is required to generate a bidirectional signal. For use with an unbalanced input amplifier with external phantom power supply, a balun transformer should be used between the phantom supply and the unbalanced input. The X-8S may also be supplied with a transformer-balanced output (such that an inline transformer is not required); however, that option will limit the X-8S to bidirectional operation only.
The X-8S is intended for use in stereo recording applications such as mid-side or Blumlein configuration. Another X-8S or X-R microphone may be used as the mid microphone in mid-side configuration. An X-R remote capsule may be mounted to the X-8S body using the mid-side mount accessory. Two X-8S microphones may be used in Blumlein configuration.
The X-8S standard output may also be split to two XLR inputs for use as a single-point stereo microphone with opposing cardioid capsules, or a two-channel microphone for recording sources on opposite sides of the microphone. To use stereo mode, the pattern selection switch must be set to the bidirectional pattern (stereo operation is not possible with the transformer-output version). A stereo XLR microphone Y cable is available as an option. The stereo Y cable has an XLR-3-F input and routes each capsule signal (pins 2 and 3 on the XLR-3-F) to pin 3 on two XLR-3-M output connectors, with impedance-balancing components on pin 2 of each output. This results in positive polarity for each capsule when connected to standard XLR microphone input amplifiers. The stereo Y cable uses a white ring on the XLR output connected to the capsule with the blind hole and a red ring to designate the unmarked capsule.
In stereo mode, the X-8S has a stereo recording angle of 90 degrees, with the frequency response of each capsule as shown below for the cardioid mode.
