Features

Skytec Professional stereo audio amplifier featuring high output power and excellent value for money.
The SKY-MKII range of amplifiers are ideal for the starting DJ, smaller fixed installations in pubs,
clubs canteens etc. or as a complement in larger disco installations.

• Outstanding sound quality

• Stereo and bridge mode

• Signal & Clip indication for each channel

• Inputs via RCA & 6.3mm jack

• Speaker NL4, 6.3mm Jack & binding post

outputs

Front Panel Features

1. Cooling Vents.

Front to rear forced airflow.

2. Signal indicators.

Three orange LEDs indicate the amplifiers output signal levels.

3. Clip Iindication.

These LEDs will light up when one or both channels are on max power. It can occur that these
LEDs will lit up now and then, this is not a problem. But if it lights up continually you need to adjust
the volume down, otherwise permanent damage to equipment might occur

4. Volume Controls.

These controls adjust the volume level of both channels. Turn slightly to the left when the clip
indicators (4) light up.

5. On/Off Switch.

For switching the amplifier on and off. Always adjust the volume down to its minimum before
switching this amplifier on.

6. Protect Indication.

When on any given point, something damaging might occur to your amplifier, it will switch in protect
mode. The amplifier will disconnect the point where the damage is about to occur and switch on the
protection led to indicate to you that something is wrong. Reasons might be: Bad ventilation,
A low impedance (< 4 Ohm), Defect fan(s), A short circuit in cables.

7. Power Indication.

This clear blue indicator will light when the amplifier is turned on.

8. Bridge Mode Indication.

signal source (mixer etc.).

3. Mode Switch.

The amplifier can use 2 different modes:
stereo & bridge.
Choose one of these functions:
Stereo mode: Standard left/right stereo
mode.
Bridge mode: This mode combines both
amps on one channel which results in
double power on this channel. Connects
the signal to the left input channel and the
output level can now be adjusted with the
left volume control.

4. Ground Lift Switch.

Allows circuit and chassis grounds to be
separated in case of problems with earth

loops (hum)..

5. 6.3mm Jack Outputs.

7. Binding Post Output Jacks.

Maximum load in stereo mode 4 Ohm per
channel. Maximum load in bridge mode 8
Ohm.

8. Mains Power Connector

9. Fuse

This main fuse secures the amplifier and
wires against defects. Replace this only
with a fuse of same type and value.

Installation

Connecting Output

Make sure the amplifier is turned off before you wire the system. Speakers can be connected using
speaker NL4 plugs or bare wire for your binding post output connectors. Using the guidelines below
select the appropriate size of wire bases on the disctance between the amplifier and speaker.
Distance Wire Size
<10m 1.5mm2
>10m <20m 2.5mm2
>20m <30m 4.0mm2

Setup operation mode

Amplfier can used in 2 modes:

1. Stereo operation

Set the mode selector (3) to the ‘stereo’ position.
In this mode the amplifier have two independed channels with there own inputs and volume controls.

2. Bridge operation

Set the mode selector (3) to the ‘bridged’ position.
This mode combines both amps on one channel which results in double power on this channel.
Connects the signal to the A input channel and the output level can now be adjusted with the A
volume control. Connect the speaker across the positive (+) output therminals. Do not use the
negative (-) terminals when the amplifier is being operated in bridged mode.

NOTE: Never connect a hot (+) output to ground or (-) output and never connect the hot (+) to
other hot outputs!

Connect to mains power

Before plugging the unit in always make sure that the power supply matches the product specification
voltage. First connect the IEC end of the cordset to the IEC connector on the amplifier then plug the
other end of the cordset to the AC mains.

Please read instructions below for reliable and problem free use:

•

Be sure all connections made are made in the correct way.

• Check if the connected speakers are compatible with the amplifier.

• Ensure there is adequate ventilation.

• Prevent exposure to moisture.

• Never plug speakers in/or out while in use, this can result in serious damage.
