How can I expand the mic inputs of the LS9?

There are several ways to expand the mic inputs of the LS9:

  • Use the MLA8, 8 channel head-amp, in combination with the MY8-AD96 card.
    This is the simplest way to expand the mic inputs.
  • Use the AD8HR, 8 channel head-amp and AD converter, in combination with the MY16-AE card, etc.
    AD8HR amplifies the level of audio signal and performs A/D conversion, and LS9 receives audio in digital format. This system cannot perform remote-control of the gain, etc. because LS9 is not equipped with RS422 connector for remote-controlling. However, this is a useful method if you already have the AD8HR unit.
  • Use the SB168-ES stage box in combination with theMY16-ES64 card.
    This method, requiring only a single CAT5e cable to connect between the SB168-ES and LS9, dramatically improves the flexibility of the layout. You can also remote-control the head-amp of the SB168-ES from the LS9.

Was this FAQ helpful to you?

After the connection between StageMix and LS9 is established, it's occasionally lost. What should be checked?

Check the following points:

- Is Wi-Fi signal strong enough? Please confirm the Wi-Fi icon in the status bar of the iPad. If the iPad is far from the wireless access point or if there are some interfering barriers inbetween, it may be required to install some wireless LAN extenders.

- Are there any other wireless access points within a short distance? If those access points are using the same or nearby wireless channels, they may possibly interfere each other. Especially in 2.4GHz band, the frequency range for each channel is very close, so it is recommended to configure the wireless access point and use appropriate wireless channels. Usually, choosing channel 1, 6 or 11 can avoid interference. Furthermore, it is recommended to use Wi-Fi checker/scanner to monitor the surrounding situation of radio waves.

 - Are there any microwave oven or Bluetooth device being used nearby? The 2.4GHz radio waves that those devices are emitting may interfere the radio signals for wireless LAN.
From radio interference point of view, therefore, wireless access points supporting 5GHz(*) band have advantages.
Meanwhile, when going through barriers, more radio intensity is lost with 5GHz compared to that of 2.4GHz. Therefore it is required to select the appropriate band, considering the environment and purpose.
*Please note that 5GHz band may not be allowed to use under certain conditions, depending on the radio laws.


- It is reported that the connection between StageMix on iOS5 and M7CL can be unstable and occasionally disconnected. As for the countermeasure, please refer to the following page.

How can I determine which IP address to be assigned to LS9 and iPad?

It is necessary to consult with your network administrator when determining IP addresses of LS9 and iPad , so that it conforms to the network policy. If there is no administer, please assign the address considering the following points.

- Assign the address which never overlaps with those of other PCs, DMEs or Mixers connected to the same network.

- If a DHCP server is running in the LAN, assign to LS9 the address that is not delivered automatically by the DHCP server.

- Please match the network address part of IP address between the LS9 and the iPad. The network address corresponds to the first three digits when their subnet mask is set to 255.255.255.0.

- When building a dedicated network for LS9 and StageMix that never connects to other networks, generally a private address such as "192.168.xxx.yyy" would be chosen.
