1. Introduction
Thank you for choosing the A.V.E. mixing amplifier SINUS - 1K with five
microphone/line inputs and a switchable CD/Aux.-Input. It was designed particularly for
superior audio quality in churches as well as other utilizations with acoustically difficult
room proportions. It’s possible to achieve an optimized acoustic pattern every time.
Each microphone/line input is equipped with a Gain-controller, a 3-band equalizer,
indicators for volume and operating status. Additionally it’s equipped with a switchable
input (CD/Aux) with a separate treble- and bass control. A graphic 9-band equalizer
acts only on the inputs 1–5.
All signal sources can be controlled by master volume control. SINUS - 1K has a VU
meter and a clipping und protection indication.
Therefore SINUS –1K is qualified to sound each kind of critical spaces.
2. Safety instructions
Please read the information provided in this manual before starting up the unit.
WITHIN THIS UNIT THERE IS DANGEROUS VOLTAGE PRESENT CONSTITUTING A RISK OF ELECTRIC SHOCK.
DO NOT OPEN THE COVER.INTERNAL MODIFICATIONS ARE TO BE COMPLETED BY AUTHORIZED
PERSONNEL ONLY.
The SINUS - 1K is equipped with an approved power cable. At one end there is a three-
pole mains connection
socket (rubber connector) and at the other end a CE-standardized Schuko-socket to
connect to a 230 V/ 50 Hz voltage source. Please take care, not to damage these power
cords. Do not use any defective or damaged power cords!

3. Description of components and their functions
1. Control dial for GAIN, THD, treble, middle and bass
The 4 potentiometers per channel allow following adjustments:
Gain: The Gain-controller customizes the amplification of the channel to the
level of the signal source of the input.
With the 3-band-equalizer (treble, middle and bass) the microphone is
adapted to the speaker to achieve an optimized sound.
Treble: ±12 dB at 10 kHz
Middle: ± 12 dB at 700 Hz
Bass: ± 12 dB at 70 Hz
2. Signal display (for channel 1 –5):
Optical display of activated e.g. overdriven input.
3. Volume control (for channel 1 –5):
With these volume controls all levels of the signal sources can be adjusted which
are plugged to the microphone/line-inputs (26). During installation by authorized
experts the optimized level will be marked with a sign.
4. Volume control for CD/Aux
5. Bass and treble control for CD/Aux
6. Master control
7. Power switch
8. 4 Output switches with optical display
9. VU meter, Out State display
Red: amplifier overdriven at input
Yellow: failure
When switching on the amplifier the LED flashes short time and disappears
afterwards.
10. Graphical 9-band equalizer
11. Channel switch CD/Aux:
Sound carrier selection. The reproducers can be connected at the backside.

7. Direct OUT +6 dB:
Direct output without any signal processing. This output can be used for example
for transmission of the direct room settings to external rooms.
8. Level Direct OUT controls the volume oft he direct output.
9. DIP switch phantom power 48 V, line, micro low, micro high

Optional Remote Control
By insertion of the print
the possibility is given to
regulate the outputs from
distance.
