The black AHB2 High-Resolution Power Amplifier from Benchmark is designed to accurately reproduce high resolution audio. The dynamic range approaches 130 dB, and the frequency response extends below 0.1 Hz and beyond 200 kHz. When reproducing high-resolution 24-bit PCM and 1-bit DSD digital audio formats, this amplifier allows you to hear nuances and dynamics which get lost when using amplifiers with lower dynamic ranges.

The AHB2 has bi-polar class-AB output stage that delivers high output current and low noise. The THX patented feed-forward error correction provides accurate cancellation of zero-crossing errors. In addition, the AHB2 uses a resonant switching power supply with a fast control loop so mechanical hum is eliminated while magnetic field strength is reduced.

Related Questions and Answers

Q: 1. I bought the 75', it does not have the signal booster, is that only with the 100'?

A: The 75' and the 100' cable sets both offer the embedded signal booster/amplifier.

Q: 2. what is the directional switch controlling?

A: the switch controls power amplitude, if the signal is coming in too strong you can back it off a little to prevent glitches. The directional portion is simply how the unit works. As long as you plug it in the correct way I've been very pleased with it.

Q: 3. Does this have a full warranty ?

A: The Benchmark AHB2 High-Resolution Power Amplifier (Black) comes with a limited 1-year manufacturers warranty.

Q: 4. What is the warranty ?

A: Warranty: Full 1-Year parts and labor

Q: 5. Is this compatible with 240V Australia? Or will I need a transformer?

A: This product as sold by B&H includes an AC to DC power supply for use in North America.

Q: 6. Can I use this cable from a Blackmagic Pocket 6K to Blackmagic Atem Mini Pro switcher without the need of boosters/converters? Please Advise ASAP? Thx

A: Your typical cable can not reach such distances at that resolution. I don't believe this one will work.

Q: 7. is this a brand new?

A: Yes

Q: 8. what color should the light be?

A: Red light means you are getting a signal. It does not turn green. I did not need to adjust the impedance. Be sure you have the amplifier on the end close to the projector. Are you using a mac or a pc? One time I hooked one of these cable to a mac and the cable would no longer work, even with a pc. I presume the amplifier was ruined but I am not sure.

Q: 9. What kind of resolution I need to adjust in my computer? Please let me know

A: You will want to set your computer to the maximum resolution of the display, monitor, TV, or projector you are using. Today, the most common resolution is 1,920 1,080 but it could be any number of other resolutions, depending on the particular monitor.

Q: 10. What is the connection in the middle of the cable for?

A: The manufacturer, Kanex, refers to it as a signal booster. It has a numbered dial which can be adjusted. I tested it when I connected a DVR with a TV. It did make subtle differences to the image. This cable worked so well, I bought a 50' one to connect an Apple TV to a video projector. That dial made a huge differences between those devices.

I replaced from pioneer d amp by this AHB2. Both product is enough great for me. But AHB2 must be quite accurate amplifier. Uncolored clear sound/amplified , that's is my comment. 5

It sounds really great. I love it. I love Benchmark.... Full Stop. 5

Perhaps the best solid state amp you can get for under $10,000? If not, within a hair of that. 5

The Benchmark AHB2 is the cleanest sounding amp I have owned across 35 years including amplifiers that cost 5X the AHB2. It only provides perfectly clean volume and nothing else. At this power output there is nothing that compares. B&H provided great service getting it to me safely. 5
