1. AC POWER Socket
AC power cord for 110V to 230V input, the supply voltage is automatically switched
between 100V to 230V.
2. 100V SPEAKER OUTPUT
The 100V output mode is only and explicitly for high impedance speakers, avoid
connecting low impedance speakers in this format. There are four independent 100V
speaker outputs that can be managed respectively. The output of these speakers is
supplied in a Euroblock connector.
Always connect the correct polarity between speaker and amplifier to avoid short circuits.
Never connect low impedance speakers to the 100V format, it may cause it to break.
3. LINE INPUT
The line input accepts balanced or unbalanced inputs, these inputs are supplied on
Euroblock connectors.
There are four independent line input channels that can be managed respectively.
4. 8Ω SPEAKER OUTPUT
The speaker outputs will be connected to low impedance speakers of 4/8/16 Ohms, pin 2
of the connector to the negative pole of the speaker and pin 3 of the connector to the
positive pole of the speaker. There are four independent 8 Ω speaker outputs that can be
managed respectively. The output of these speakers is supplied in a euroblock connector.
Never mix the negative and positive end, which may cause short circuit protection.
Never connect the 100V line speaker to these 8 Ω ends as they may damage the unit and
speaker.
5. Volume control
The volume control is used to adjust the input volume.
6. HIGH PASS FILTER
The high pass filter function will be enabled or disabled by presetting the separate
four-channel DIP switch. There are separate four-channel high-pass filters that can be
managed respectively.
7. AUTOMATIC STANDBY
The auto standby function will be enabled or disabled by presetting the separate
four-channel DIP switch. The auto standby feature enabled will automatically enter
standby once no input has been detected within 2 minutes. The amplifier will activate
immediately once the input signal is detected.
8. 100V and 70V line switch
Switch to toggle high impedance output between 70V or 100V.
