Applications

This PA stereo has especially been designed for stage and disco applications. Extensive protective circuits protect the amplifier and the speakers connected.

Setting-Up

The amplifier is provided for rack installation (482 mm/19"), but it may also be used as a table top unit. In each case air has to move through all ventilation slots without obstruction so that a sufficient cooling is ensured.

4.1 Rack installation

For rack mounting 2 rs (rack spaces = 89 mm) are required. Additional space should remain above and below the amplifier to ensure a sufficient ventilation. To prevent the rack from becoming top-heavy, the amplifier has to be mounted in the lower part of the rack. The front plate alone is not sufficient as a secure fastening. The unit has additionally to be supported by side rails or a bottom plate.

Connecting the Amplifier

All connections must only be carried out with the unit switched off! 1) Connect the output of a preamplifier or mixer to the XLR or 6.3 mm jacks INPUTS (16 and 22). Both jacks are provided for balanced signals; the pin configuration is shown in figures 4 and 5. The input signal should have line level. Depending on the position of the selector switch for the SENSITIVITY of the input (21), an input signal of 1 V, 1.6 V, or 3.2 V is required as a minimum for a rated power of the amplifier. 2) The maximum output power is reached in 2-channel operation (stereo or parallel) when connecting 4 speakers. It is also possible to connect 8
speakers, however, the output power will slightly decrease in this case. In bridge operation the maximum output power will be reached with an 8 speaker. The required power rating (PMIN) of the speakers is listed in the table fig. 6. Connect the speakers to the SPEAKER jacks (14), pin configuration see fig. 3, or to the terminals (15). When using the SPEAKER jacks (14), the contact pairs 1+/1- or 2+/2- can be used, as in the unit the contact 1+ is connected to 2+, and the contact 1- to 2-. When connecting the speakers, pay attention to the same polarity of all speakers. For bridge operation connect the positive pole of the speaker to the positive terminal of the left output and the negative pole of the speaker to the positive terminal of the right output. (The positive terminal of the right output becomes the negative pole for the speaker by the signal inversion in bridge operation.) For models STA-1800 and STA-2400, the speaker can alternatively also be connected to the SPEAKER jack OUTPUT BRIDGED MODE (13). In this case the normal pin configuration will apply, i. e. the speaker is connected to 1+/1- or 2+/2- (see fig. 3). Table fig. 6 also shows possibilities of connection for several speakers to one output. In each case it is stated which power rating (PMIN) each speaker must have as a minimum with the corresponding impedance (Z). When interconnecting several speakers, it is especially important to pay attention to the correct connection of the positive and negative contacts and that the minimum total impedance is 4 for 2-channel operation and 8 for bridge operation. 3) Finally connect the mains cable to the mains jack (24) [only for models STA-800 and STA-1100]. Connect the mains plug of the cable to a socket (230 V~/50 Hz). Prior to the first switching-on, set the controls (6 and 8) to the left stop to -.

6.4 Groundlift-Schalter

Ist ohne ein Musiksignal ein strendes Brummen zu hren, kann eine Masseschleife die Ursache sein. Masseschleifen knnen entstehen, wenn zwei Gerte sowohl ber die Signalmasse als auch ber den Schutzleiter der Stromversorgung oder eine leitende Verbindung der Gehuse im Rack Kontakt haben. Um die so entstandene Masseschleife aufzutrennen, den Groundlift-Schalter (19) auf Position LIFT stellen.
6.5 Pegelbegrenzung (Limiter)
Ein Limiter regelt das Eingangssignal zurck, wenn ein Grenzpegel am Ausgang erreicht wird. Dadurch lassen sich bei bersteuerung des Verstrkers Verzerrungen vermeiden, die die Lautsprecher schdigen knnten. Mit dem Schalter LIMITER (20) lsst sich diese Begrenzerschaltung ein- (ON) und ausschalten (OFF).

Operation

6.3 Level adjustment
Adjust the output of the mixer or preamplifier to its rated level (0 dB) or the maximum undistorted output signal. With the switch SENSITIVITY (21) match the input sensitivity of the amplifier to the output level of the mixer or preamplifier. Turn up the controls (6 and 8) until the maximum desired volume is reached. If the LEDs CLIP (5 and 9) show the overload of the amplifier, slightly turn back the controls. Caution! Never adjust the volume on the amplifier very high. Permanent high volume may damage your hearing! The human ear will get accustomed to high volumes which do not seem to be that high after some time. Therefore, do not further increase a high volume after getting used to it.

Protective circuit

6.1 Switching on/off
To prevent loud switching noise, always switch on the power amplifier in an amplifier system after all other units have been switched on and switch it off first after operation. After switching-on, the LEDs PROT (2 and 12) light up for a few seconds. During this time the switch-on delay is activated for the protection of the speakers.
6.2 Selecting the operating mode
Select the desired operating mode with the switch MODE (18): 6.2.1 Stereo operation If the switch is in position STEREO [the LEDs BR (3) and PAR (11) do not light up], both channels are operated independent of each other. 6.2.2 Parallel operation If the switch is in position PAR [the LED PAR (11) lights up], the input signal of the left channel is switched in parallel to the left and right channels. A signal at the right input is ignored. The volume adjustment is made with the left control (6) together for both outputs. 6.2.3 Bridge operation If the switch is in position BR [the LED BR (3) lights up], the input signal of the left channel is additionally switched to the right channel in an inverted way. Thus, the voltage at the output is doubled if the speaker is connected for bridge operation, as described in chapter 5. A signal at the right input is ignored. The volume adjustment is made with the left control (6) together for both outputs.

The protective circuit is provided to prevent damage to the speakers and the amplifier. If it is activated, the LEDs PROT (2 and 12) light up and the speakers are switched off: 1. for a few seconds after switching-on (switch-on delay) 2. if the amplifier is overheated 3. if a DC voltage occurs at the output If a short circuit occurs at the speaker output, the CLIP LED (5, 9) of the corresponding channel lights up. If this is the case or if the LED PROT lights up during operation or if it is not extinguished after switching-on, the amplifier must be switched off and the cause for the defect must be eliminated.

6.4 Groundlift switch

If an interfering hum noise can be heard without a music signal, a ground loop may be the reason for this. Ground loops may occur if two units have contact both via the signal ground and via the earthed conductor of the power supply or a conductive connection of the housings in the rack. To separate the ground loop thus occurring, set the groundlift switch (19) to position LIFT.

6.5 Level limiting

A limiter reduces the input signal if a limit level at the output is reached. In case of overload of the amplifier it is thus possible to prevent distortions which could damage the speakers. With the switch LIMITER (20) it is possible to switch ON and OFF this limiter circuit.
