Powering 50W into 25V, 70.7V, or 4 ohms systems, the AA50PHD from Atlas Sound is a 4-input mixer amplifier designed for distributed-business paging, background music systems (BGM), small-to-medium speech-privacy systems, or any situation in which music-on-hold is a must.

Featuring one microphone/line input, one 1/8" input, and two RCA stereo-summing line inputs—as well as a variety of connection possibilities via the rear panel—the AA50PHD allows you to group inputs together for the purpose of muting/attenuating them by any signal affecting channel one. A rear-mounted DIP switch affords you more muting options, and a preamp out/power amp-in is useful for external processing, should you require it. Finally, a remote input selector port comes standard on the back of the mixer, allowing you to control the unit with Atlas Sound accessory items (sold separately).

Q: 1. Can you load a mix to two tracks and have it there for others to more add tracks later?

A: Yes, you can import a file (such as the master bounce of a mix) into a project using a USB flash drive in USB HOST mode. After importing a file, you can use all other open channels to record more tracks.

Q: 2. Can you link two of the mono tracks in the setup to have additional stereo inputs from the 2 that are on the L20?

A: Yes, you can use any of the individual mono input channels to connect instruments, mics or other devices in order to create a stereo input. For example, if you are using a stereo microphone or connecting a keyboard that has two separate outputs for left and right, you can certainly connect each output to a different individual mono input on the L-20.

Q: 6. Is there a maximum recording time per song?

A: With a 128 GB SDHC/SDXC Memory card, you can activate all 20 channels for recording and record for 10 hours and 56 minutes. Recording on just one channel yields 80 hours, 13 minutes. (2 channels = 60 hours 10 minutes) This is at a 44.1 kHz, 24 Bit rate and bit depth. At 96 khz, 24 bit, 1 track will run for 36 hours, 51 minutes and 20 tracks will record for 5 hours, 1 minute. If you want to use 48 kHz, 24 bits,, 1 track is 73 hours, 42 minutes and 20 tracks is 10Hr. 3 min. Recording at 16 bits? Multiply these times by 1.5. This is the total time for as many songs as you have. If they each run 4 minutes, you can record a lot of songs before you have to empty the memory card. I've found my machine to be a solid performer! Very clear recordings!
