SMi series - Professional SMPS stereo amplifiers
1
Unbalanced RCA input socket
Allows you to receive asymmetrical line-level signals.
Signals are spread as follows:
- Tip = signal
- Body = Ground
The input sensitivity of this socket is set at 0,775V.
2
Jack TRS input socket
Allows you to receive line-level signals. This socket is
able to receive both symmetrical and asymmetrical
signals. However, we recommend to always use
symmetrical signals as they get you rid of parasitic
noises caused by low quality cables. Connect here your
male Jack plug. Polarities are spread as follows:
- Tip = Signal +
- Ring = Signal -
- Body = Ground
3
XLR input socket
Allows you to receive line-level signals. This socket is
able to receive both symmetrical and asymmetrical
signals. However, we recommend to always use
symmetrical signals as they get you rid of parasitic
noises caused by low quality cables. Connect here your
male XLR plug. Polarities are spread as follows:
- Pin 2 = Signal +
- Pin 3 = Signal -
- Pin 1 = Ground
4
Input sensitivity selector
Allows you to select the input sensitivity of both
channels. This selector can be used as follows:
- 1,4V when XLR or Jack TRS inputs are balanced.
- 1,0V when XLR or Jack TRS inputs are unbalanced.
- 0,775V when using the RCA input.
Please refer to paragraph 6 for more details about
balanced and unbalanced connections.
Note: this selector only affects XLR and Jack TRS
inputs.
5
Low Boost selector
Allows you to increase basses levels by 6dB. This
increase affects the frequency by 80 Hz.
6
Parallel / Stereo / Bridge selector
Allows you to select the current amplifier mode:
- Stereo: Standard mode, each channel amplifies its
own signal. (Minimum impedance of 2 ).
- Parallel: Input 1 signal is identically amplified by both
channels. (Minimum impedance of 2 ).
- Bridge: Both amplification channels are added up to
amplify Input 1 signal. (Minimum impedance of 2 ).
7
Cooling vents
Allow the air to flow through the amplifier to cool down
its internal components.
Please do not obstruct these vents as it may result in
overheating and damage the internal components.
8
Output terminals
Allows you to directly connect stripped cables.
Use the Red terminals to connect your speaker
in "Bridge" mode.
Warning: Dangerous output voltage!
9
Speakon® outputs
Allow you to connect your speakers via cable equipped
with Speakon® connectors. Please refer to next chapter
for more information about connections.
10
Power input
SMi600 and 1000: plug here the supplied power cord to
connect your amplifier to an electrical outlet.The SMi600
also features a fuse.
SMi1500 and 2000: the power cord is already attached
to the amplifier to prevent the use of cables not powerful
enough.
11
Fuse (only for SMi1500)
If need to replace this fuse, please make sure the
new one has the exact same characteristics in
order to prevent serious and permanent damage
to your amplifier.
