UNPACKING INSTRUCTION
CAUTION! Carefully unpack the box upon receipt. Check the contents to ensure that all parts are present and have been
received in good condition. Notify the shipper immediately and retain packaging material if any parts appear damaged from
shipping or the package itself shows signs of mishandling. Save the package and all packaging materials. If the product must be
returned, it is important that the product is returned in the original factory box and packaging.
If the device has been exposed to drastic temperature fluctuation (e.g. after transportation), do not switch it on immediately. The
arising condensation water might damage your device. Leave the device switched off until it has reached room temperature.
POWERSUPPLY
The label on the back/under side of the product indicates the mains voltage to which it must be connected. Check that the mains
voltage corresponds to this. Any other voltage than the one indicated may cause irreparable damage to the unit. The unit must
also be connected directly to the mains voltage and no dimmer or adjustable power supply may be used.
Always connect the device to a protected circuit (circuit breaker or fuse). Make sure the device has an appropriate
electrical ground to avoid the risk of electrocution or fire.
OVERVIEW
1. OPERATION INFO LEDs
LEDs showing amplifier working status (protect, clip, input signal, output signal).
2. POWER ON/OFF SWITCH
Switch to turn the amplifier on/off. When turned on, the power LED will be illuminated.
3. POWER INPUT
Socket for plugging in the supplied power cord.
4. GROUND / LIFT SWITCH
Switch to choose between ground and lift. In lift position, the amplifier eliminates unwanted hum and buzz by interrupting the
ground loops between equipment.
5. LINE INPUT
Connector block with 4 separate line input sockets. Supports both balanced and unbalanced input.
6. SPEAKER OUTPUT
Connector block with 4 separate output sockets. Both 100V line output and 8Ω output is supported.
100V connection:
8Ω connection:
7. VOLUME LEVEL
Rotate to adjust the input volume per channel.
8. HIGH PASS FILTER
Dipswitches to enable/disable the high pass filter for all channels separately.
9. AUTO STANDBY
Dipswitches to enable/disable the auto standby function. When enabled, the channel will go into standby mode when no
signal is detected for 2 minutes. When signal is detected, the amplifier will "wake up" automatically.
10. VOLTAGE SWITCH
Switch to enable operation of both 70V and 100V.
