Frequently Asked Questions

Access™ Demonstration System Questions

See also Access Tips

Q: What is Access?
A: Access is Audio Authority's modular system that can be configured and scaled up to any size or complexity. We also make other specialized switching systems, but all Access modules and user interfaces work together, whereas the other "stand-alone" systems we make do not necessarily interact with Access. See Access Tips for more information.


Q: How does Bypass work?
A: By establishing an alternative route, bypass allows the demo system to play an audio system with or without in-line components such as amplifiers or processors. To activate bypass, simply turn off all products in the product group you wish to bypass. This causes the signal flow to skip over the entire group and move on to the next product group in the signal path.


Q: How does Addressing work?
A: Addressing is the way the Access Network determines what modules belong to which groups, and which modules are first, second, third, etc.  It is very similar to finding a physical house address. You need to know what street the house is on, and which house number it is. Group number is like the street, and Module ID is like the house number. For more information, click here, or see page 15 in the Access Home Audio Manual Access Home Audio Manual [View] (5.17 MiB) for detailed instructions.


Q: Can I use multiple control panels in one system?
A: Yes, sometimes. The 906 control panel is designed to control one product group. You can use several 906 panels, one for sources, one for amplifiers, and one for speakers.


Q: How can I switch HDMI signals?
A: It is possible to program our Model 970A-1 to interface with an HDMI switch that has a serial control port. See this HDMI receiver demo example and call Audio Authority for details.


Q: Can I use a tablet or other device as an interface for my Access switching system?
A:
Yes, the 903i Comparator is an industrial tablet with switching software that is ideal for systems with multiple product groups. For custom solutions,  you can use any device that can send serial commands to control an Access system. The Model 970 module converts RS-232 commands into Access commands and sends them out via RS485. See the 970 manual for more information.


Q: Can I use 2-wire buttons with the new 4-pin PSB ports?
A:
 Yes, you can use 2-pin switches on any 4-pin PSB port. Use the two pins on the left (depending on the orientation of the port). access_tip4d


Q: Can I select positions without a control panel or PSB?
A:
 Yes, you can use a small metal tool, such as a screwdriver, to short the pins of the PSB port. 


Headphones and Portable Audio Questions (1700 and 1800 Series Products)


Q: What is the best way to demonstrate high-end headphones?
A: Use a powerful headphone amplifier that can push the headphones to perform at their peak. You should switch the output so that the amplifier is dedicated to one pair of headphones at a time.  You can provide a master volume control for all headphones, or use individual volume controls for each pair.


Q: What is the simple way to demonstrate headphones?
A: A simple approach is to play music through all headphones all the time. You can provide a master volume control for all headphones, or use individual volume controls for each pair.  Details.


Q: Can I use 2-wire buttons with 4-wire PSB ports?
A:
 Yes, you can use 2-pin switches on any 4-wire PSB port. Use the two pins on the right (depending on the orientation of the port). 


Q: Can I use lossless audio formats?
A: Yes. We offer systems that play FLAC, WAV, and high bit-rate MP3 files.  Details.
