2. Receiver Setup

Introduction

The receiver assembly consists of the Sennheiser AMBEO VR mic and Shure 4-channel preamp mounted on a microphone stand.

You will need:

  • A microphone stand (not included an IRIS kit)
  • Sennheiser AMBEO VR Mic with mic stand mount and breakout cable
  • Shure ANI4IN-XLR preamp
  • iOMounts NOMAD magnetic mounting system
  • 30 m STP Cat5e Ethernet cable

Magnetic Mount

The Revision 3 kit uses a magnetic mounting system for attaching the Shure preamp to the leg of a mic stand. A metal disc must be adhered to the bottom of the preamp and allowed to set for at least 8 hours before use. This step will have already been completed for premade IRIS kits, but otherwise follow the instructions that come with the iOMounts NOMAD.

Tip

You may need to remove some of the stickers on the bottom of the preamp and clean the surface before attaching the disc.

The metal disc on the bottom of the preamp looks like this:

The other part of the product is a strap with a mating magnet, which should be attached to the leg of a mic stand, as shown in the above photo.

Tip

We recommend you leave the strap permanently fixed on your mic stand. It can be difficult to remove the mount once it has been attached, though it's definitely possible if necessary.

Receiver Setup Procedure

  1. Setup a mic stand.

  2. Attach the Sennheiser AMBEO VR Mic to the stand using the included mic clip.

    The front of the mic is labelled FRONT, which indicates the positive x-direction. We recommend aligning the positive x-direction in the same direction as a listener at that position.

    Tip

    ISO 3382-1 specifies a receiver height of 1.2 m (seated listener).

  3. Place the Shure 4-channel preamp on the mic stand using the magnetic mount.

  4. Connect the mic to the preamp using the 4-channel breakout cable. Ensure the channels are connected in the correct order: channel 1 of the mic must go to channel 1 of the preamp, channel 2 to 2, and so on.

  5. Connect one end of the 30 m STP Ethernet cable to the Dante port on the Shure preamp (we'll connect the other end soon).

    Tip

    Use the velcro tie or some electrical tape to tie the Ethernet cable to the mic stand as a strain relief.

  6. Place the mic stand at the first receiver position.

The completed receiver assembly should look something like this:
