POWER IN Terminal block connection for the device‘s power supply. To avoid damage to the device, please use only the original power supply (power supply included).

STRAIN RELIEF Use the strain relief for the flexible cable of the power supply unit to protect the device‘s power terminal block connector and the power supply terminal block from damage and to prevent the terminal block from being pulled out unintentionally.

LINE IN 1 / 2 Analogue audio inputs with balanced terminal block connections. The +, - and G poles are for the balanced input signal (suitable for unbalanced cabling). Terminal blocks are included in the packaging content.

OUT 1 / 2 Loudspeaker outputs 1 and 2 for connecting low-impedance loudspeakers (ST and PAR mode: min. 4 ohms each; HPM mode min. 2 ohms). Please observe the correct assignment of the terminal block poles (see TERMINAL BLOCK CONNECTIONS in this manual). The total power handling of the connected speakers should be approximately equal to the amplifier power.

MODE Before using the unit, make sure that the switch is in the correct position! ST: Stereo mode. LINE IN 1 is sent to OUT 1, LINE IN 2 to OUT 2. PAR: Parallel mode. LINE IN 1 and LINE IN 2 are mono summed and sent simultaneously to OUT 1 and OUT 2. The volume of the two channels is adjusted individually with the VOLUME 1 and 2 level controls on the front panel. HPM: The High-Power mode allows users to connect speakers or speaker lines with an impedance of 2 ohms to the amplifier (amplifier power. 100 W @ 2 Ohm). Using higher impedance loads may not fully utilize the benefits of HPM mode. Use LINE IN 1 as the signal input and the VOLUME 1 level control on the front panel to adjust the volume. CAUTION! Please observe the correct assignment of the terminal block poles (see TERMINAL BLOCK CONNECTIONS in this manual). DEUTSCHFRANCAIS ESPAÑOL ENGLISH ITALIANO POLSKI10

SETTINGS DIP switch 1 AUTO STB: Move the switch to the ON position to activate the unit‘s automatic standby function. If the standby function is activated, the amplifier is automatically set to standby mode if no audio signal is detected for about 20 minutes. In this way, power consumption is sensibly reduced. As soon as an audio signal is present again, the amplifier is automatically booted up from standby mode and is fully operational again within approx. 3 seconds. The power symbol on the front panel lights up red in standby mode. If the Power-symbol lights up white, the unit is ready for operation. DIP switch 2 GAIN +12dB: Move the switch to the ON position to boost the pre-amplification of the line inputs LINE IN 1 and 2 by 12 dB. Before switching to + 12 dB, make sure that both level controls 1 and 2 on the front of the unit are set to minimum (left stop).

STANDBY Standby mode can be activated manually using an external button (momentary switch). Press the button to activate standby mode and mute the speaker outputs. Press the button again to end standby mode. The standby function via external button has priority over the automatic standby function (see SETTINGS).

VCA Terminal block connections for the use of external volume controls. ST and PAR MODE: In stereo and parallel mode, one volume control per channel can be used independently (VCA 1 and VCA 2). The maximum volume is set on the VOLUME 1 and 2 volume controls on the front panel. HPM: In High Power mode, use the VCA 1 connection. The maximum volume is set on the VOLUME 1 volume control on the front panel. Once you have set the maximum volume, you can use the external volume control to adjust the volume of the unit from the minimum value to the preset value as desired. Please observe the correct assignment of the terminal block poles (see TERMINAL BLOCK CONNECTIONS in this manual). ITALIANO POLSKI ESPAÑOL FRANCAIS DEUTSCHENGLISH11

POWER SYMBOL The power symbol lights up white when the installation amplifier is ready for operation. In standby mode, the symbol lights up red.

VOLUME 1 / 2 One level control each for channels 1 and 2. Turning to the right increases the volume, turning to the left decreases it.

SIG 1 / 2 (SIGNAL) As soon as an audio signal is present at channel 1 or 2, the corresponding signal indicator lights up white.

CLIP 1 / 2 The red CLIP indicator lights up when the corresponding channel is overdriven. In this case, reduce the volume level. Failure to do so may result in distorted sound reproduction and damage to the amplifier and speakers.

HPM As a visual indication that the high power mode is activated, the HPM indicator lights up white (see point 5 MODE).

PROT (PROTECT) The Protect indicator lights up permanently if the system is overloaded or overheats, in case of a short circuit in the loudspeaker path and in case of a defect. The amplifier is automatically muted. Disconnect the amplifier from the power supply and let it cool down for some time. Eliminate a possible short circuit in the speaker path. Reconnect the amplifier to the power supply. If the Protect indicator still lights up, there is a defect in the amplifier electronics. Contact an authorised service workshop. AIR VENTS To prevent damage to the device, do not cover the ventilation openings on the left and right sides and on the top and bottom of the device and ensure that air can circulate freely. Covering the ventilation openings on the top or bottom of the housing when mounting it underneath or on top of a table is not critical, since the cooling provided by the the ventilation openings on the remaining sides is sufficient.
