The white AcousticCoverage Series QSC AC-S4T 4" 2-Way 16W Loudspeaker Pair Whiteis a pair of transformer-equipped 4" surface-mount loudspeakers voiced to deliver enhanced clarity in the vocal range, making them suitable for 70/100V or 8-ohm operation in a variety of paging, A/V conferencing, and background music applications.

Outfitted with a 4" polypropylene woofer and a 1" aluminum dome tweeter in a UV-treated ABS enclosure with a ported baffle, the AC-S4T offers broad 130° conical coverage while providing a frequency range of 70 Hz to 20 kHz (-10 dB). The speaker is capable of handling 16W RMS and producing a peak maximum SPL of 103 dB.

The AC-S4T utilizes a 4-pole Euroblock connector on the rear panel for easy input and loop-thru wiring. A yoke bracket is included for simplified surface-mount installation.

Q: 1. I want to be able to use AA batteries as a backup. Can you tell me is the design flaw mentioned in the one star(*) review has been resolved?

A: I have used these radios for some time now. I have ordered and different models of the Midland GXT radios. I always carry and use the AA batteries as backup and never have had a problem in doing so. It is a tight fit which in my opinion is good, I don't have to worry about a rattle.

Q: 2. will arca swiss plates work with this tripod?

A: I have PMG plates on my spotting scope and telephoto lenses and they perfectly fit this head.

Q: 3. Can I use the headphone output to input to a camera?

A: You can take audio out from the headphone output, but it is line level. Also, this mic must be connected to a computer for power and to control the volume level to the headphone out.

Q: 4. Does this microphone have Automatic Gain Control?

A: This microphone does not offer an AGC. Gain levels are adjusted manually.

Q: 5. Does it have friction control?

A: No, but you can slightly tighten the controls to create makeshift friction.

Q: 6. Is there away to change the Base Mount thread to 1/4"?

A: Certainly! All you'll need is a 3/8"-16 reducer bushing like this one: https://bhpho.to/2WxKgYY or https://bhpho.to/34upiOY

Q: 7. Is the QR adjustable fore and aft? Is there a name for this feature?

A: The QR can be adjusted but it does not have a lot of range unfortunately.

Q: 8. If I wanted to point my camera straight up can this head accomplish that? Would I have to turn the camera a quick release plate around backwards?

A: I use a Manfrotto 410 geared head which has the same limited up pointing constraint. I mount my telescope, which obviously needs to point way up, on it. To get around the up pointing constraint I mount the QR plate with the telescope pointing "backwards." When I connect the telescope to the mount I am using the downward pitch as my upward pitch. Since the Benro plates are Arca-Swiss comparable there is no front or back to them. To maintain 3-way operation I would mount the plate in line with the optical axis of the camera and mount the camera to the head with the lens pointing out over the pitch handle. That is going to require reaching around the head to got to that handle which will be a little awkward, but allows control of pitch, yaw, and roll which becomes limited if the camera is mounted "sideways" as suggested by Staff.

Q: 9. Can I use it like an gimbal head ? Can I lock the horizon and just move up and down with circle move ?

A: It may be the closest head to a gimbal but you will achieve much results with a gimbal head as far as tracking and smoothness of motion.

Q: 10. Can i use this as substitute to my Benro FSL09C? Thanks

A: Yes it can be used as a substitute for the head on the Benro FSL09C tripod.
