**MZ-123BT**commercial-grade multi-zone audio mixer. The compact, single rack space MZ-123BT builds on the feature-set of its big brother, the 2U MZ-223, adding Bluetooth-functionality and a simple front... Read more

**Maximum speaker cable lengths for :**

- Low impedance (2, 4, 8 and 16 ohm)

- Quality
- 3 dB loss, which could be an alternative to a line transformer system

- High impedance (systems with line transformer)

- 70V
- 100V

## Low Impedance

Results are for a total damping factor of 25, using an amplifier with a damping factor of 400 and signa loss of 0.3 dB. 25 is the minimum damping factor for a "quality installation". For higher quality, specially for bass, the above recommended lengths would be halved

Results are for a signal loss of 3 dB and are in practice independent of the amplifier damping factor

## Alta Impedancia (*High Impedance)*

Results are for a signal loss of 1 dB. For 3 dB loss, multiply the maximum lengths by 3.5

Results are for a signal loss of 1 dB. For 3 dB loss, multiply the maximum lengths by 3.5

NOTE: A comma is used as decimal separator instead of a colon. Multiply the resistance/100 m value by 0.3048 to get a value for resistance/100 feet. Multiply meter lengths by 0.3048 to get lengths in feet.
