GRACE DESIGN E407

Product overview

The GRACE DESIGN E407 is the 53 cm bar of the GRACE DESIGN Spacebar modular microphone positioning system: a 7/8 in diameter tube with a laser etched centimetre scale that reads 25-0-25 cm from the centre.

Spacebar mic holders, the SB-TJ90 90 degree tube joiner and the stand mount adapters clamp onto the bar wherever they are needed, and their sight holes line up with the centimetre indicator circles engraved on the tube. Microphone spacing can be set precisely and repeated from session to session. On the SB-SUR surround tree, mic holder spacing on the 53 cm bar can be set from 6 cm to 50 cm.

Key features

GRACE DESIGN E407: frequently asked questions

How do I set microphone spacing on the bar?

Clamp the mic holder on the tube and line up its sight hole with the centimetre indicator circles of the engraved scale, then tighten the clamping handle clockwise. The clamp is very secure and needs no extreme torque.

Where is the E407 used in the standard Spacebar arrays?

The bills of materials list one E407 in the SB-SUR surround tree and one in the SB-BL Blumlein array.

Where can I buy the GRACE DESIGN E407 in India?

The GRACE DESIGN E407 is available from Shivansh Electronics, Kolkata, West Bengal, India, with delivery across India.

Connections

Setup

1. Clamp the E407 in the SB-TJ90 joiner, centred with the joiner's sight holes.
2. Fit two mic holders and set the spacing on the 25-0-25 cm scale.
3. Fit the E414 end plugs and tighten every clamping handle.

Tip: The centre-zero scale makes symmetrical left and right spacing quick to read.

Workflow 2: Short stereo bar for a spaced pair

Studios and location recordists needing a compact bar.

Connections

Setup

1. Clamp the stand mount adapter at the centre of the bar.
2. Set both holders the same distance from the 0 mark.
3. Angle each microphone with the holder's protractor scale.

Tip: Note the scale readings so the setup can be repeated exactly.
