The Sontronics Apollo is an active stereo ribbon mic based on the Sigma, another ribbon microphone from Sontronics.
The Apolloʼs dual transducers are in a fixed XY configuration, and since both ribbons offer a bi-directional polar response, the Apollo functions as a Blumlein mic. The ribbons are independent of each other, allowing for use of the Apollo as a mono ribbon microphone.
One of the primary benefits of stereo microphones is that they eliminate many of the difficulties associated with accurate placement for stereo recordings. The Apollo is no exception, though only for Blumlein setups. Since both ribbons are fixed in their positions, other stereo configurations such as ORTF are not an option.
According to one reviewer, the Apollo does not perfectly address another issue inherent to stereo setups: gain matching.

| The C 414 B/XLS has been carefully designed to maintain the legendary sonic character of the C 414 family while integrating new features and performance enhancements made possible by new technology. The C 414B/XLS is designed to deliver accurate pickup of all acoustic instruments and voices.
The microphone's 5 pickup patterns are easily selectable via an electronic switch with LED indication and offer the selection of omnidirectional, cardioid, wide cardioid, hypercardioid and figure-eight patterns.
The pickup pattern selector switch utilizes a dual-color LED indicator that provides visual indication of the pattern selected and also changes from green to red to indicate if the microphone's output electronics are being overloaded. The pattern selector can also be used to "lock" the microphone's switch settings by pressing and holding it for 3 seconds.
On the rear of the microphone, an electronic switch allows the selection of -6 dB, -12 dB and -18 dB pre-attenuation levels which are accomplished by changing the polarization voltage to the capsule. The C 414 B/XLS has switchable bass cut filters of 12 dB-per-octave at 40 Hz and 80 Hz, and a 6-dB-per-octave filter at 160 Hz for control of proximity effect. On-axis sensitivity for all patterns is 23 mV/Pa and its self-noise is an extremely low 6 dB-A.
The C 414 B/XLS has a transformerless output and all-metal chassis, making it immune to electrical interference and RF from digital equipment, video monitors and wireless systems. It comes complete in an all-metal road case with the AKG H-85 shock mount, a PF80 external two-stage pop filter, a W414X external windscreen and an individually-measured chart showing the response curve of the microphone. It is also available in factory-matched stereo pairs packaged with a H50 stereo bar instead of the external pop filter.
The C 414B/XLS is built in Vienna, Austria and comes with a three-year limited parts and labor warranty.

The earlier model C 3000 has had a large fan club in the project studio and home recording worlds for years. For the new C 3000 B, AKG designed a special 1-inch large-diaphragm transducer that closely approximates the vibration performance of top-class studio microphones, but can be made at much lower cost.
Due to its surface area and special capsule tuning, the C 3000 B large-diaphragm transducer produces an exceptionally pleasing, smooth sound. Unlike in the C 3000, the switchable 10-dB preattenuation pad immediately follows the transducer in the signal path, thus increasing the C 3000 B\'s SPL capability by a true 10 dB. Loud sound sources are therefore no problem.
An acoustically optimized cardioid polar pattern makes the C 3000 B an excellent choice for both recording and live sound applications where high gain before feedback is paramount.
