What is AmpliTank K688?
The AmpliTank K688 is a dynamic microphone from FIFINE that works over both USB and XLR. You can plug it into a PC or console by USB, or into a mixer or interface by XLR.
The pickup pattern is cardioid, and FIFINE says it helps reduce background noise such as computer fans and hard drives. The listed maximum SPL is 130 dB, for loud sources.
With USB, the 3.5 mm headphone jack on the mic lets you monitor in real time, and a dedicated gain knob and mute button are available. Per the page, these work only over USB.
The box contains a USB cable, windscreen and shock mount, but no XLR cable. Built-in 3/8-inch and 5/8-inch threads let you mount it on a mic arm directly. The official store price is $102.99, and the page showed a notify-me option instead of an add-to-cart.
The official page lists variants alongside the K688: K688X, K688NEO, K688CT and K688NEOCT. This entry concerns the standard AmpliTank K688, shown in black (white also appears in images).
Besides PCs, it is listed as compatible with PS4 and PS5 over USB. For XLR use it connects to a sound card or mixer, but no XLR cable is included. The page shows badges for a 30-day money-back guarantee and warranty and support, without terms.
USB and XLR
Use USB for instant PC use, or XLR for audio gear. You could start on USB and later move to an interface.
Cardioid pickup
Focuses on the voice in front and helps reduce fan and drive noise, as FIFINE describes. It may suit rooms with background sound.
130 dB SPL
The listed maximum SPL is 130 dB, a figure that fits loud voices and close-up use.
Real-time monitoring
A 3.5 mm headphone jack with its own volume knob lets you hear yourself live. This works over USB only.
Mute button
A button on the mic mutes it instantly, handy on streams and calls. USB connection only.
Mic arm threads
Built-in 3/8-inch and 5/8-inch threads let you mount it on arms and stands, and a shock mount is included.
PS4 and PS5 support
Over USB it is listed for PS4 and PS5 as well as PCs, which may suit console voice chat.
3/8-inch and 5/8-inch threads
Both threads are built in, so a thread adapter is less likely to be needed for arms.
Shock mount and windscreen included
A shock mount and windscreen are in the box for desk setups.
