Pearl ELM-T – User Manual

2. Introduction

Founded in 1941, Pearl Microphones is one of the oldest, continuously

operating microphone manufacturers in the world.

Every Pearl microphone is handcrafted in our plant in southern Sweden. Our

quality control is meticulous, and all microphones must pass several stages of

testing, including rigorous audio tests in our anechoic chamber.

We believe in our products, which is why every microphone is delivered with

its own individual frequency chart and our industry-leading lifetime warranty.

Since 2017, Pearl Microphones is a trademark of Milab Microphones AB.

Congratulations on your purchase and welcome to the Pearl & Milab family!

Thomas Nöjdh, President

Milab Microphones AB

4. Pearl ELM-T Microphone

The Pearl ELM-T Bernt Malmqvist Signature Edition is a high-end

vacuum-tube microphone, built entirely by hand in Sweden. The heart of the

microphone is the Pearl ELM rectangular condenser capsule with a height-to-

width ratio of 7:1. The ELM-T has been meticulously designed by Mr. Bernt

Malmqvist who has been a part of Pearl Microphones since 1954.

The capsule and the vacuum tube are delicate components, and the

microphone should be handled with care. Exposure to liquids, humidity,

power surges, extreme temperatures, or external force (etcetera) may affect the

performance of the microphone or in worst case cause permanent damage.

The ELM-T is not intended to be used as a handheld device and should always

be used with the enclosed shock mount. Make sure that the microphone is

fitted firmly so that it does not fall out of the shock mount.

The microphone is side-addressed and in a directional mode such as cardioid,

the side with the Pearl badge should be aimed at the sound source.

For close-up vocals, we recommend the use of an external pop filter to protect

the microphone capsule and to reduce pops and plosives.

6. Connecting and operating instructions

Your specific microphone, power supply unit (PSU) and microphone cable

have been optimised and matched by our engineers and should be regarded as

one operational unit. This means that your ELM-T microphone should only

be used with the PSU and cable that it was delivered with.

Connecting the microphone and PSU

Step 1: Connect the microphone cable to the connector at the bottom of the

microphone.

Step 2: Connect the microphone cable to the 7-pin connector on the PSU.

Make sure that the locking mechanism is firmly screwed tight.

Step 3: Connect the 3-pin XLR output on the PSU to a microphone input on

your mixer or preamp, using a balanced XLR cable. Ensure that the input

channel is muted before connecting the XLR cable.

󱛻󱛼󱛽IMPORTANT! Make sure that the microphone is connected to the PSU

before the power is switched on.

Connecting the PSU to power

Step 1: Ensure that the voltage setting on the PSU corresponds to the voltage

of the power grid.

Step 2: Check that the power switch on the PSU is set to “off”.

Step 3: Connect the PSU to a grounded power outlet using the enclosed

power cable.

Step 4: Set the power switch on the PSU to “on”.

If everything has been connected correctly, the microphone will power up and

start to function within ca 30-60 seconds after power has been switched on.

Please note that the vacuum-tube circuitry needs time to warm up. Therefore,

it is highly recommended to leave the power on for at least 10 minutes

before using the microphone.

Pearl ELM-T – User Manual

󱛻󱛼󱛽IMPORTANT! The PSU offers two different voltage settings, 115 V and

230 V. Always make sure that the voltage setting corresponds to the

voltage of the power grid. Using the wrong setting may result in damage

to the equipment.

Changing the polar pattern

The Pearl ELM-T offers a range of polar patterns (cardioid, omni,

bidirectional and intermediate positions) via a selector on the power supply

unit (see page 5). When using a directional pattern (like cardioid) the side of

the microphone with the Pearl badge should be aimed at the sound source.

󱛻󱛼󱛽IMPORTANT! A tube microphone is a delicate instrument which must

be handled with care. The Pearl ELM-T system should only be used indoors

and not be exposed to humidity or temperatures above normal conditions.

7. Cleaning and storing

Disconnect the power cable from the power supply unit before cleaning.

The microphone and PSU may be cleaned with a soft damp cloth. Alcohol or

methylated spirits can be used to carefully clean the metal surfaces.

󱛻󱛼󱛽IMPORTANT! Always protect the capsule/membranes and electronics

when cleaning.

When the equipment is not in use it should be stored in a dry place at room

temperature. Use the enclosed microphone slipcover or store the microphone

in its case to protect the capsule from dust and dirt.

8. Troubleshooting

This guide can help you troubleshoot some issues you may encounter. If the

problem persists, please contact your local dealer/distributor or Milab

Microphones directly.

No sound

Possible cause

Possible solution

No power to PSU and/or mic

Ensure that all cables are properly connected.

Make sure that the PSU power switch is turned

on (see page 5).

Check PSU fuse (see page 5).

Signal path issue

(Problems with mixer/preamp,

cables or connectors)

Make sure that mixer/preamp is working, that

the channel is unmuted, and volume is up.

Ensure that the XLR cable is working and that

it is properly connected. Replace if necessary.

Make sure that the microphone cable (between

PSU and mic) is properly connected at both

ends.

Distorted sound, noise, pops and/or clicks

Possible cause

Possible solution

Overloading mixer/preamp

Turn down gain on mixer/preamp

The vacuum tube needs more time

to warm up

Ensure that the system has been powered up

for at least 10 minutes before use.

Sound pressure level is too high

Increase the distance between mic and sound

source.

Popping/plosive sound when

recording vocals

Use pop filter; increase the distance between

mic and singer.

Pearl ELM-T – User Manual

Polar pattern is being changed (or

has just been changed)

Wait a few seconds for the electronics to

stabilise. Noise/distorted sounds when

changing the polar pattern is normal,

especially when switching between omni and

bidirectional patterns (and vice versa).

Air humidity too high

Reduce humidity levels or move the

microphone to a location with lower humidity.

Condensation caused by sudden

temperature change

Let the microphone acclimatise before use.

9. Lifetime warranty and service

Your microphone is covered by Milab’s lifetime warranty.

The warranty is intended to protect the customer from manufacturing and/or

material defects. It does not cover careless or improper handling (intentional

or unintentional) such as physical negligence, electrical overload etc.

Detailed terms and conditions apply and can be downloaded from our website.

Visit www.milabmic.com/warranty for more information.

If you should experience a problem with your microphone, please contact your

dealer/distributor or Milab directly for further instructions. You can also make

a service request directly on our website: www.milabmic.com/service-request/

Please note that all technical service should be carried out by Milab

Microphones or by a party that has been approved by Milab.

Opening/disassembling the microphone or power supply unit, or making any

modifications to the equipment that cannot be considered “normal use” will

void the warranty.
