Rack Installation
The SL Series are rack mountable. The rack you use should be a double door rack where you can
open the front and rear panel. When mounting the amplifier into the rack, please make sure that
there is enough space around the amplifier.
Be careful when mounting the amplifier into the rack. Put the heaviest products into the lower
part of the rack. Be aware that fastening the amplifier with four screws on the front panel is not
enough.
Inputs
Short cables runs improve the sound quality remarkably. Input cables should be short and direct,
since high frequencies will mostly be absorbed if the cables are unnecessarily long. Besides that
a longer cable may lead to humming and noise problems. If the cable runs are unavoidable, you
should use balanced cables.
Outputs
The high damping factor of your amplifier supplies a clear sound reproduction. Unnecessarily long
and thin cables used for low impedance (4-16Ω) speakers will influence the damping factor and
thus the low frequencies in a negative way.
Connect your speaker systems via the speaker terminals (COM = -VE)
Examples: 1) COM + 4-16Ω
2) COM + 70V
3) COM + 100V
Note: Please do not use more than one pair of output terminals
Identification:
1. Power LED - This LED will light up once the amp is switched on
2. SIGNAL LED - This LED will light up when signal is being received
3. CLIP LED - This LED will flash when the output signal starts to distort. A this point turn the
master volume anti-clockwise to prevent damage.
4. PROT LED - This LED will illuminate when the unit goes into protect mode. Switch off the
amplifier and check the output connections for faults or short circuits before powering on and
resuming operation.
5. TEMP LED - Temperature LED will illuminate when overheating. Switch off the amplifier
and leave to cool down.
6. FAN Ven t - Don not obstruct, keep clear of dust
7. On/off power switch -
Use the switch to power the unit on or off
8. Master volume control - Use this control to increase or decrease the master volume
9. Carry handles
10. GND/LIFT switch - Switch to “GND” position when one unit is used, switch lift “LIFT” when
several units are used to avoid noise caused by several earth
line grounded.
11. DC LED -
This LED will light up when optional DC power supply is used
12. FAN Vent - Do not cover to avoid overheating
13. Speaker outputs - Use these to connect the speakers
14. XLR input - Use this to connect signal input from mixer amplifiers
15. 6.35mm mono jack input - Use this to connectsignal input from mixer amplifiers
16. 6.35mm mono jack link - Use this to link out to additional slave amplifiers
17. XLR link - Use this to link out to out to additional slave amplifiers
18. 24V DC connections
- Use this to connect to your optional 24V DC power supply
