The W 30 is a newly designed, two-layer windscreen. Two

different materials provide optimum rejection of wind

noise. The dark-gray outer layer swirls the impinging air

stream. The colored inside layer is more permeable to air

and acoustically neutral. It steadies the air stream before

2 Description

Note:

Note that both the maximum working distance and the

area covered by the microphone depend on the pickup

angle. The smaller the pickup angle (hypercardioid), the

longer the maximum distance between the talker and the

microphone and the smaller the area covered by the

microphone.

Whether an omnidirectional, cardioid, or hypercardioid

capsule will give the best results therefore depends on

the specific application situation (see Table 1).

Omnidirectional capsules are primarily suited for record-

ing and lavalier use.

4.3.1. Tabletop

Installation

All Discreet Acoustics Modular Capsule Modules are con-

denser microphones and therefore require a power supply

(phantom power). The Installation Modules have been

designed for connection to microphone inputs with 9 to

52 V phantom power. To connect Installation Modules to

inputs without phantom power, refer to Section 4.6.

1. Screw the Capsule Module onto the Installation

Module.

The screw thread is relatively fine and therefore very

smooth-running. Make sure not to tilt the capsule

when placing it on the Installation Module thread

because this would damage the thread.

2. To lock the capsule, use commercial minimum-tack

screw locking adhesive that allows you to unscrew

the capsule later if need be.

Before replacing a Capsule Module, be sure to

switch your sound system OFF in order to prevent

unwanted noise.

1. Use the supplied PS 3 F-Lock panel mount socket to

install the Installation Module in a tabletop or an

optional SA 40 or SA 50 stand adapter to mount the

Installation Module on a floor or table stand.

Note: For even better vibrational noise rejection, you can

fix the Installation Module to the tabletop with an

optional H 500 (see fig. 13) or H 600 + A 608 shock

mount (see figs. 14 and 15).

2. Use a shielded cable to connect the Installation

Module to a microphone input with phantom power.

3. If the phantom power on your mixing console is swit-

chable, switch the phantom power on. (Refer to the

instruction manual for your mixing console.)

The Capsule Module and the LED ring (see Section 7)

will be powered from the phantom supply.

1. Drill an 11-mm (7/16”) hole through the tabletop.

2. Thread the connecting cable of the Installation

Module through the opening and the supplied fixing

screw.

3. Screw the fixing screw into the Installation Module

from below to fix the Installation Module in place.

Audio Connection

Note: For even better vibrational noise rejection, you can

fix the Installation Module to the tabletop with an optional

H 600 + A 608 shock mount (see figs. 14 and 15).

1. Plug the cable of the DPA phantom power adapter

into the female mini XLR connector on the connecting

cable of the Installation Module.

2. Use a shielded cable to connect the DPA phantom

power adapter to a microphone input with phantom

power.

3. If the phantom power on your mixing console is swit-

chable, switch the phantom power on. (Refer to the

instruction manual for your mixing console.)

The Capsule Module and the LED ring (see Section

4.7) will be powered from the phantom supply.

You may also connect the GN 15, GN 30, and GN 50

installation modules to a PT 60, PT 61, PT 80, or PT 81

bodypack transmitter from AKG.

All you need to do is change the wiring of the mini XLR

connector as shown in fig. 1 below:

Pin 1: shield

Pin 2: red wire (in phase)

Pin 3: bridge to pin 2

Blue wire: unused

Black wire: unused

This Installation Module has been designed for 1.5 V to

10 V a-b powering. The unterminated cable provides the

following connections:

Blue: LED +

Black: LED -

Connect the microphone wires to a microphone input

with a-b powering. Connect the LED ring referring to

Section 4.7.

1. Prior to installing the microphone, straighten the

cable by carefully pulling it through your fingers. Make

sure not to buckle or twist the cable.

2. Fasten a hook to the ceiling, use an existing hook, or

stretch a line across the hall.

3. Pass the cable through the hook or over the line so

that it will hang at the desired height.

4. Fix the cable in place with electrician's tape. This will

prevent the cable from twisting.

Do not tie a knot into the cable to hang it on the

hook. This may cause the cable to twist and misalign the

microphone after a while.

5. Hold the cable with one hand and turn the micro-

phone carefully into the desired position as shown in

fig. 2.

Note: If you installed the microphone as described

above, the special cable will not twist and will stay

aligned even if the temperature changes.

Audio Connection:

4.5. LM 3, LM 3L

Lavalier Modules

To keep the microphone steady even in a draft,

1. Stretch a suitable length of fishing line horizontally

across the room, passing the fishing line through the

eye on the HM 1000.

2. Fix the fishing line to two opposite walls so as to

create just enough downward pull to steady the

microphone laterally.

Refer to Section 4.3. GN 15, GN 30, GN 50 Audio

Connection.

1. Screw the capsule module onto the connection

socket of the lavalier module (see fig. 5a).

2. To relieve the microphone of the strain of the cable,

insert the cable into one of the grooves in the upper

part of the clamp (see fig. 5b).

4 Installation and Connections

4.5.1. LM 3 Audio

Connection

3. Snap the connection socket of the lavalier module

into the holding claws on the clamp.

The holding claws let you fix the connection socket in

a 12, 3, 6, or 9 o’clock position.

4. Clamp the microphone on the user’s clothing (see

fig. 5b) as close as possible to the user’s mouth.

Remember that gain-before-feedback will be the

higher the smaller the distance between the micro-

phone and the mouth!

5. Make sure to aim the microphone at the user’s mouth.

Note: You may also clamp the microphone to

suitable decorations (e.g., a backdrop).

1. Insert the DPA phantom power adapter into the belt

clip and fix the phantom adapter on the belt.

2. Use a shielded cable to connect the DPA phantom

power adapter to a microphone input with phantom

power.

3. If the phantom power on your mixing console is

switchable, switch the phantom power on. (Refer to

the instruction manual for your mixing console.)
