FAQ

Q: Can the amplifier support 8-Ohms on one channel and 70V on the rest?

A: Distortion may occur when certain source signals exceed the input capacity. It's important to note that using 70V and 8-Ohm configurations simultaneously is not feasible. Specifically, the 6-zone cannot accommodate 8-Ohm speakers. If you intend to connect 8-Ohm speakers, they should be connected solely to the 4-16 Ohms terminal of the main output, with no connection to any other 70V terminals.

However, if all the speakers are rated for 70V, multiple speakers can be connected simultaneously. In this scenario, they can be connected to both the main output of 70V-100V and the 6-zone. Each zone within the 6-zone can handle approximately 200W but the total amplifier capacity is capped at 360W, including the main output and 6-zone sum.

 

Q: What type of speakers can the 6-zone connect to?

A: Speakers that do not have a transformer can't be connected to the 6-zone settings on the amp, it can only connect to the 4~16 ohm terminal and can only connect a certain amount depending on the impedance. If the impedance of one speaker is 8-ohm, 2 in parallel is 4-ohm, so the amp can only connect to two 8-ohm speakers. The 6-zone connection can only be connected to a high impedance speaker (with transformer). Connecting a low impedance speaker to a high output impedance amplifier causes impedance mismatching, resulting in amplifier malfunction or damage.

 

Q: Does it have the ability to connect an exterior medium such as a phone line or IP phone, or similar to be able to dial into it and page via a communication medium while not being directly in the same building as the amplifier itself?

A: No, the amp does not have IP communication.

 

Q: Can your amplifier work with multiple lines at different voltages at the same time; for example: 100V, 70V, 4 Ohms & 8 Ohms etc?

A: Low impedance 4-16 Ohms can't work at the same time with 70V/100V.

 

Q: What speaker wire should be used for this system?

A: Speaker wire is not included. To ensure optimal performance and minimize signal loss, select the appropriate wire gauge based on the distance between your amplifier and speakers:

Distance Wire Gauge 10–15 ft 18 AWG 15–25 ft 16 AWG 25–50 ft 14 AWG 50–100 ft 12 AWG Over 100 ft 10 AWG

Using a thicker (lower gauge) wire for longer runs helps maintain signal strength and overall audio quality.

 

Q: Can the USB tracks be randomized and not in the same order?

A: Yes
