SCHOEPS STC

Product overview

The SCHOEPS STC is an ORTF mounting bar that holds two microphones at the exact distance and angle for ORTF stereo recording.

It is a mounting adapter for CCM compact microphones, the CMC 1 L or KC active cables. The holder ensures that two cardioid microphones (CCM 4 / MK 4) keep the exact distance and angle to each other for the ORTF method, which gives excellent stereophonic characteristics: very good localisation and very good spatial quality.

An ORTF-like technique is achieved with open cardioids (CCM 22 / MK 22). Their lower directivity makes the level difference smaller, so the recording angle becomes larger. The STC 22 is therefore slightly longer and compensates with larger time differences, giving the same recording angle as the ORTF technique. The STC 4 is the version for cardioids. An SG 20 stand clamp is included.

SCHOEPS STC: frequently asked questions

What is the difference between the STC 4 and the STC 22?

The STC 4 spaces the microphones 170 mm apart for ORTF with cardioids. The STC 22 spaces them 210 mm apart to compensate the lower directivity of open cardioids with larger time differences, giving the same recording angle as ORTF.

Which recording angles result?

STC 4: 100° with MK/CCM 4 and 114° with MK/CCM 22. STC 22: 90° with MK/CCM 4 and 100° with MK/CCM 22. The microphone offset angle is 110° on both.

Which microphones and cables fit?

CCM compact microphones such as the CCM 4 and CCM 22, the CMC 1 L amplifier with a capsule, or KC active cables. The AK 2L/SU Y cable for the CMC 1 L and CCM is recommended.

Where can I buy the SCHOEPS STC in India?

The SCHOEPS STC is available from Shivansh Electronics, Kolkata, West Bengal, India, with delivery across India.

Workflow 1: ORTF pair with CCM 4

Engineers recording ensembles, choirs and ambience in stereo.

Connections

Setup

1. Fit the two CCM 4 into the STC 4; distance and angle are set by the holder.
2. Mount the bar on a stand with the SG 20.
3. Connect the microphones and set equal gain.

Tip: The STC 4 gives a recording angle of 100° with cardioids.

Workflow 2: Quasi-ORTF with open cardioids

Recordists who prefer the CCM 22 or MK 22.

Connections

Setup

1. Fit the two open cardioids into the longer STC 22.
2. Mount it on a stand and aim it at the centre of the source.
3. Fit B 5 D wind and pop shields when needed.

Tip: With CCM 22 the STC 22 gives the same 100° recording angle as ORTF with cardioids.
