Introduction

The information contained in this Quick Start Guide is sucient for proper installation of E Series ampliers, and for conguration of

settings in typical applications. Please refer to the full Operation Manual for detailed information on maintenance, cooling requirements,

warranty, and conguration for complex installations .

This equipment conforms to the EU requirements of the EMC Directive 2004/108/ EC and Low Voltage Directive 206/958/EC valid until April 19. 2016. From April 20. 2016 the equipment complies to EU directives for EMC 2014/30/EC and Low Voltage Directive 2014/35/EC

Standards applied: EMC Emission EN55103-1, E3 EMC Immunity EN55103-2, E3, with S/N below 1% at normal operation level. Electrical Safety EN60065, Class I

This equipment is tested and listed according to the U.S. safety standard ANSI/ UL 60065 and Canadian safety standard CSA C22.2 NO. 60065. UL made the tests and they are a Nationally Recognized Testing

Laboratory (NRTL).

Unpacking and visual checks

Every Lab.gruppen amplier is carefully tested and inspected before

leaving the factory and should arrive in perfect condition. If any damage is discovered, please notify the shipping carrier immediately. Save the packing materials for the carrier’s inspection and for any future shipping.

Installation

The 2 channel ampliers are 276 mm (10.9 in) deep and their weight is approximately 4.2 kg (9.2 lbs) depending on model.

The 4 channel ampliers are 382 mm 15,0 in) deep and their weight is aproximately 6,6 kg (14,4 lbs) depending on model.

Free air ow from front to rear is required for cooling. No doors or covers should be mounted either in front of or behind the ampliers.

Ampliers may be stacked directly on top of each other with no

spacing, though some spacing may enable more convenient installation of rear cabling.

Cooling

E Series devices use a forced–air cooling system with airow from

front to rear, allowing high continuous power levels without thermal

problems. Ensure that there is sucient space in front of and behind the ampliers to allow for free air ow. Please refer to the full Operation

Manual for thermal dissipation value when installing large numbers of

ampliers in air conditioned spaces.

NOTE: Fit solid blanks (not ventilation blanks) to unused rack spaces to ensure eective air circulation. Leaving gaps in between items of equipment degrades the eectiveness of forced–air cooling.

Operating voltage

All E Series ampliers have a universal power supply that operates

on mains from 100 – 240 V at 50 or 60 Hz. The IEC receptacle on the rear panel accepts the supplied IEC cord which terminates in a connector appropriate for the country of sale. When AC power

is connected, the amplier goes into standby (amber indication on power LEDs). It will go on if the power button is pressed (or if signal is supplied to either input or if the GPI is closed). The power LED

shows green for “on” indication.

Grounding

For safety reasons, never disconnect the earth (ground) pin on the

AC power cord. Use balanced input connections to avoid hum and

interference. Signal ground is oating via a resistor to chassis, and

therefore grounding is automatic.

Explanation of graphic symbols

The lightning bolt triangle is used to alert the user to the presence of un-insulated “dangerous voltages” within the unit’s chassis that may be

of sucient magnitude to constitute a

risk of electric shock to humans.

The exclamation point triangle is used to alert the user to presence of important operating and service instructions in the literature accompanying the product

To prevent electric shock do not remove top or bottom covers. No

user serviceable parts inside. Refer servicing to qualied service

personnel.

To completely disconnect this equipment from the AC mains, disconnect the power supply cord plug from the ac receptacle. The mains plug of the power supply cord shall remain readily operable.

Warning

To reduce risk of re or electric shock, do not expose this apparatus

to rain or moisture.

Do not expose this system/apparatus to dripping or splashing and

ensure that no objects lled with liquids, such as vases, are placed

on the apparatus.

This apparatus must be connected to a mains socket outlet with a protective earthing connection.

The mains plug is used as a disconnect device and shall remain readily operable.

Audio inputs

Audio inputs are electronically balanced and use three-pole Phoenix-type connectors. Follow the +, - and Ground labels when making connections.

Loudspeaker outputs

Loudspeaker outputs use detachable block-type connectors. Maximum connector current rating is 41 Arms (exceeding capacity

of the amplier). Cables up to 4 mm

(12 AWG) can be accommodated.

Observe polarity to avoid low frequency cancellation loss.

Front panel

The front panel presents the following amplier status indicators:

POWER – Bi-color LED indicates standby (amber) and on (green).

TEMP (temperature) – Flashing amber indicates excessive

temperature in the power supply unit (PSU) or output stage(s).

When temperature exceeds the danger threshold, the LED

shows steady amber and the amplier mutes.

The following indications are per channel:

SIG (input signal present) - Green indication when input signal

exceeds signal present threshold.

LIM (limit) – Illuminates when the amplier limits the signal.

Limiting is engaged when the channel:

• Reaches the selected voltage limit threshold (as determined

by model and position of Rail Sensing Limiter (RSL) switch)

• Rail voltage sags below the selected threshold

• Maximum current output reached

• Mains voltage cannot maintain rail voltage

Rear panel

Important note on Auto Power On/O – All E Series ampliers include an Auto Power Down/On (APD) scheme. As shipped (factory default), the amplier will go to low power standby mode

when no signal is present for 20 minutes. It will return to power on mode when signal exceeds the signal present threshold. For information on calibrating the signal present threshold, please refer to the Operation Manual.

Power button and indication - When pressed momentarily, toggles power state between standby and on. Indicator shows amber for when it goes into standby and red if it is forced into standby by pressing the power knob and green for on.

Attenuators - Range is 0 dB to -innity; vertical is -10 dB. Amplier

sensitivity is 4 dBu with attenuator at 0 dB and 14 dBu at -10 dB.

SIG - Illuminates green when input signal above Signal Present

Threshold (SPT). For adjustment of SPT value, please refer to the

full Operation Manual.
