GENERAL USE H20

The ampliﬁer is switched on with the button in the middle of the

front panel. A blue light indicates it is switched on.

The ampliﬁer has two types of audio inputs: unbalanced audio

signal with phono plugs (RCA) and balanced audio signal with XLR

plugs (pin 2 is positive phase, pin 3 is negative phase and pin 1 is

chassis ground).

Selecting between balanced and unbalanced inputs:

Use the signal input selector (1,3) and point it in the

direction of the input you want to use.

NOTE: Do not connect both balanced and unbalanced cables at the

same time.

NOTE: We strongly recommend that the ampliﬁer is turned off when

you switch between the inputs, and while connecting cables. Not

doing so may potentially harm your speakers.

After the ampliﬁer is switched on, there is a delay of about 10-30

seconds before the speaker outputs are turned on.

GENERAL USE H30

The Hegel H30 is a mono-block ampliﬁer that may be used as a

stereo power ampliﬁer. Read more about the mono / stereo con-

nection on page 8.

The ampliﬁer has two types of audio inputs: unbalanced audio

signal with phono plugs (RCA) and balanced audio signal with

XLR plugs (pin 2 is positive phase, pin 3 is negative phase and

pin 1 is chassis ground). You can switch between the two inputs

with the designated switches (ﬁg. left. Number 6 and 12)

NOTE: Do not connect both balanced and unbalanced cables at

the same time.

NOTE: We strongly recommend that the ampliﬁer is turned off

when you switch between the inputs, and while connecting

cables. Not doing so may potentially harm your speakers.

TRIGGER INPUT/OUTPUT

The H30 has a trigger input and output. If connected, a steady

5-12V signal will turn the outputs on. When the signal is 0V sig-

nal the output will be turned off. The trigger output allows you to

daisy chain more H30’s or other devices. The trigger port uses a

regular 3,5 mm jack plug.

The trigger port will function with most trigger outputs (5-12V)

from other manufacturers, but is only guaranteed with HEGEL

trigger outputs. Connecting a trigger port with output more than

12V may harm the ampliﬁer and is not covered by the warranty

GENERAL USE P20

The ampliﬁer is switched on with the button in the middle of the

front panel. A blue light indicates it is switched on. To the left the

channel selector with selections: Balanced, CD, Video, Tuner, Auxil-

liary and Home Theatre, and to the right the volume control. The

selected input is indicated by a blue light.

When the mute button on the Hegel Remote Control is pressed, the

ampliﬁer outputs are muted. Mute is indicated by a ﬂashing blue

power light. To go back to normal operation press the mute button

one more time. After the ampliﬁer is switched on, there is a delay of

a few seconds while the volume control circuit is being calibrated.

Avoid connecting input cables without making certain the unit is

completely turned off. We also recommend that you reduce volume

levels before changing inputs, as either may damage your loud-

speakers.

WARNING: The Home Theatre input bypasses the volume control.

Connecting a regular source to this input may potentially harm you

system and your hearing.

GENERAL USE P30

The P30 has two types of audio inputs: unbalanced audio signal

with phono plugs (RCA) and balanced audio signal with XLR plugs

(pin 2 is positive phase, pin 3 is negative phase and pin 1 is chassis

ground).

After the ampliﬁer is switched on, there is a delay of about 60

seconds while the volume control circuit is being calibrated. This is

indicated by the ﬂashing blue power LED. When the LED stops ﬂash-

ing and gives a steady blue signal, the P30 is ready to operate.

The ampliﬁer is switched on with the button on the front panel. To

the right you have the volume attenuator, and to the left the input

selector knob.

If you have a source with fully balanced outputs, we recommend you

use high quality balanced cables to connect the source to the P30.

WARNING: The Home Theatre input bypasses the volume control.

Connecting a regular source to this input may potentially harm your

system and your hearing.

pre amp to the mono input on your H30

3: Connect the mono +

and mono - terminals on

the H30 to your loud-

speaker.

2: Make sure the switch is

SETTING UP THE H30 IN MONO MODE

The H30 is intended to be run as a mono block. As such it will drive

virtually any speaker on the market.

To use the H30 as a mono block, connect each of the mono blocks as

described in the ﬁgure “Mono mode” (upper right).

WARNING: The H30 is extremely powerful and it is important that

you make the connections and ﬂip the mono switch when the ampli-

ﬁer is turned completely off. Not only with the trigger switch.

We do recommend you use balanced (XLR) interconnect cables of

good quality to obtain the best sound quality.

SETTING UP THE H30 IN STEREO MODE

The H30 may also be used as a stereo power ampliﬁer, and will

deliver in excess of 300 watts pr. channel in this conﬁguration.

Hook it up as described in the ﬁgure “Stereo mode” (lower right)

WARNING: The H30 is extremely powerful and it is important that

you make the connections and ﬂip the stereo/mono switch when the

ampliﬁer is turned completely off. Not only with the trigger switch.

We do recommend you use balanced (XLR) interconnect cables of

good quality to obtain the best sound quality.

RC8 REMOTE CONTROL

All HEGEL pre ampliﬁers can be controlled by the included HEGEL sys-

tem remote control, RC8. Like with other HEGEL products, the number of

buttons is kept to a minimum.

The input source is selected by pressing IN+ and IN-, the volume is

adjusted by pressing VOL+ and VOL-. The Mute function toggles on and

off by pressing the MUTE button. The HEGEL system remote control will

also control other HEGEL products like CD-players and integrated ampli-

ﬁers. When used with a P30 pre ampliﬁer, pressing the ECO-button will

set it in a low power mode.

The remote control is using 2 standard 1.5-volt LR03 AAA batteries. To

insert the batteries please use a normal type cross head screwdriver

to gently remove the four screws in the bottom of the remote control.

Be careful and use a normal cross head screwdriver to remove the four

Philips cross head screws.

Be sure to insert the batteries with the correct polarity with + sign and

– sign as shown inside the battery holder, and be careful when insert-

ing the batteries to not damage the battery holder.

Be careful when inserting the screws after ﬁtting the batteries. Please

turn the screws gently by hand ﬁrst to avoid damaging the threads in

the remote control body. Do not tighten the screws to hard, as this also

can damage the screws and the soft metal body of the remote control.

Please do not drop the remote control hard down in the ﬂoor, as this can

damage internal parts of the remote control and the battery holder.

USE/PLACEMENT

The ampliﬁer should be placed on a ﬂat, hard surface for prop-

er cooling. The ampliﬁer performs best after being switched

on for 1 hour for heating up. Plenty of space is required for air

circulation above, below and around the ampliﬁer. The ampli-

ﬁer must never be placed on a carpet or similar surface that

obstructs air circulation through the component. Nor must it be

covered while in use or placed on a narrow shelf or in another

conﬁned space.

Always use the main power switch on the front panel to

switch the ampliﬁer on and off. Never switch on or off the AC

voltage supply to the H20 or H30 with an external switch.

The ampliﬁer will automatically switch itself off if overheated

(H20 and H30).

The ampliﬁer will need some break-in time before maximum

sound quality can be experienced.

CLEANING

The top, side and front panels are made of bead blasted and

anodized aluminium. Fingerprints can be wiped with a damp

cloth.

NOTE/WARNING

HEGEL products must never be opened by anyone other than

certiﬁed technicians. The devices contain electronic compo-

nents that can cause electric shock. Work performed on HEGEL

products by unqualiﬁed persons can cause serious damage and

personal injury. The products must not be exposed to rain or

moisture.

WARRANTY

All HEGEL products come with a 2-year guarantee against

defective materials and workmanship.
