Apex Electronics 460
Multi-Pattern Tube Condenser Microphone
The Apex 460 is a Chinese-made tube condenser microphone, usually considered by the audio community to be a rebadged Alctron HST-11A. Lookalike mics vary in capsule and component details; see, for example, the ShuaiYin SYT-1200.
The mic’s large-diaphragm capsule is a 32mm Chinese K67 copy, advertised as having 5-micron membranes although in reality this specification varies without notice.
The mic supports 9 polar patterns, switchable from the power supply.
At $229, the Apex 460 is a phenomenal buy.
This is one of many AKG C12 lookalikes, and is possibly one of the best-known and most widely available; as a result, much work has been done by hobbyists to mod this mic, such as replacing the capsule and transformer and some components on the circuit board.
The Apex 460’s early claim to fame was its appearance in a teardown analysis by StudioReviews.com, proving that the mic was identical to the original and short-lived 2005 edition of the R-F-T M16 — a mic costing (at the time) significantly more, and which was subsequently replaced by a significantly nicer product at the same price.
- Upgrade the stock transformer to a Cinemag, Samar Audio, or AMI model.
- Upgrade the capsule; see a full list of available aftermarket large-diaphragm capsules
- Replace the Chinese tube with a higher-grade 12AT7 or 6072
- Various circuitry changes are possible, too; search the forums for details
The spec for a complete T-11A/Apex 460 mod can be found in the Yahoo “Micbuilders” group; see the German C24 Solo Tube Condenser plan (you must first join the Micbuilders group).
