12. Permanent hearing loss may be caused by exposure to extremely high noise levels.
The US. Government’s Occupational Safety and Health
Administration (OSHA) has specified the permissible exposure to noise level.
These are shown in the following chart:

Hours x day

8

| SPL

90

| Example

Small gig

---|---|---
6| 92| Train
4| 95| Subway train
3| 97| High level desktop monitors
2| 100| Classic music concert
, .5| 102|
1| 105|
0.5| 110|
0.25 or less| 115| Rock Concert

According to OSHA, an exposure to high SPL in excess of these limits may result in the loss of heat. To avoid the potential damage of heat, it is recommended that Personnel exposed to equipment capable of generating high SPL use hearing protection while such equipment is under operation.

The apparatus shall be connected to a mains socket outlet with a protective earthing connection.

The mains plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain readily operable.

Control Element

POWER LED

The Green LED light up when the amplifier power on.

CLIP LED
This red LED lights up when the input signal is too strong. it is time to reduce input level until clip LED turns off.
SIGNAL LED
These green LEDs light up when the respective channel’s output signal pass through.
PROTECTION LED
In normal operation, the LED will not illume; If the LED turns red, it means the unit is in heat protection without sound output. The speaker system is actually disconnected from the amplifier outputs when this LED is red, the tern perature must be reduced by good ventilation and the signal level decreased etc, if the problem is resolved. the protection output systems will deactivate automatically, and normal amplifier operation is resumed.

REAR PANEL

Control Element

Power Switch
It switches ON/OFF the unit main power.
AC Input
Use it to connect your unit to the supplied AC cord.
Level Control
These volume controls allow you to adjust the volume level.
Euro block input
INPUT+: balanced signal input+ or unbalanced signal input
INPUT G: signal GND
INPUT – : balanced signal input- or unbalanced signal not connect
Euro block Output
Connect the amplifier to your speakers using these Euro block.

Control Element

Exhaust Vents
Air is drawn from front grilles. flowing through the unit and heat sink. and then exhausted via the rear vents. Do not block or impede the air flow through these vents and keep the vents areas free of foreign materials.

Applications

Inputs connections

The inputs can be connected to the Euroblock socket using the female free part connectors supplied with the device.
For balanced inputs use Hot pin(+), Cold pin(-) and Ground pin (G) terminals.
For unbalanced inputs use Hot pin(+) and Ground pin (G) only.

Speaker connections

Check that the polarity is well respected for every speaker.Two Eroblocks connected point to point are available for easy patroller setup. The impedance output must not be higher than 2 Ohms per channel.
