The Shure Beta 91A is a boundary microphone that can double as a kick drum mic, as it can capture the punch and attack of low-frequency instruments such as kick (bass) drums. It features a wide frequency response well suited for capturing a variety of audio signals such as organ and piano. The flat, boundary design also aides in producing a strong, solid low-end response, as well as make it easy to mount inside of a bass drum. The Beta 91A is ideal for both recording and sound reinforcement alike.

Wide Frequency Response    Low-Profile Design    Cardioid Polar Pattern    Interchangeable Cartridge

Uniform half-cardioid polar pattern for maximum gain-before-feedback and rejection of off-axis sound

Low-profile design features integrated preamplifier and XLR connector to facilitate setup efficiency while minimizing stage clutter

Frequency response tailored for kick drum/low frequency applications with a wide dynamic range for use in high SPL environments

Two-position contour switch to maximize attack and clarity depending on application: select the flat response setting for natural sound in most applications or the Low-Mid Scoop setting for a strong low frequency punch with plenty of higher frequency attack

Q: 1. Would this be a good camera to use the aps c mode

A: Yes, the Sony a7 IV Mirrorless Camera (B&H# SOA74) allows for use in cropped (APS-C) mode both during video and still shooting. That cropping increases the effective focal length by 50%, something that video shooters in particular will especially appreciate.

Q: 3. Can I use the same USB C cable that came with my Canon EOS R8 to transfer photos to a Macbook Pro?

A: The Sony a7 IV Mirrorless Camera comes with a USB Type-C to Type-A cable, and all MacBook Pros after 2016 don't have a USB-A port, so either you have to use a USB-A to USB-C adapter or you get a USB-C male to USB-C male cable. You can find the options here: https://bhpho.to/4d8tUe2.

Q: 8. I have the Fuji GFX camers with lots of Megapixels. Want a 2nd lighter camera for wildlife and bird. Cannot decide between the A7 IV and the A9 ii. What are the main differences besides megapixels and FPS?

A: The a9ii has a stacked sensor that allows the sensor to be scanned very quickly. So it has less rolling shutter in video and you can also use it in silent electronic shutter and not get distortions. Unfortunately the a7iv does not have the stacked sensor, so you get more rolling shutter distortions and in silent mode you can get banding. Better to only use the a7iv in regular mechanical shutter.
