Mono / Stereo Analogue Audio Distribution Amplifier

1. Equipment description.

1.1. Basic design concepts.

The DA-26 is an analogue audio distribution amplifier with 2 input audio channels and 12 output

audio channels. Both inputs and outputs are transformer balanced.

You can configure the DA-26 to work in Mono or Stereo mode. In Mono mode 1 input and 12

outputs are available. In Stereo mode 2 inputs and 6 outputs per input are available.

You can change the working mode just by pushing a button located on the front panel.

1.2. Gain.

Independent gain control (between -∞and +15 dB) is provided for each individual output.

1.3. Adjustments.

All the outputs are adjusted by default with a gain of 0 dB. Due to the load impedance of the

equipment that are receiving the distributed signal or due to different level requirements, in

some installations it may be necessary to make a little gain adjustment in order to get the

desired output level. You can use an oscillator as input generator and use a trimmer to regulate

the front potentiometers in order to adjust each output level.

2. Equipment power supply.

The equipment receives power through the connector designed for that purpose (located on the

back panel), using the cable supplied. The equipment may be operated with alternating voltage

of between 90V and 250V at 50 or 60 Hz. Maximum consumption is approximately 45W.

To turn on the equipment, you must activate the power switch (ON position) located on the front

panel. If all instructions have been correctly followed, the Power ON LED will light up, indicating

that the equipment is receiving power.

4. Signal connections.

To make the audio connections, it’s recommended to extract previously the male connectors.

We recommend you to mark the first terminal position (IN+) in order to avoid a wrong cabling.

You can extract the connector by pulling. When you connect it again there’s only one possible

position, but take care that it’s not displaced one or more pins because it wouldn’t work or would

produce noise.

Connections must be made with a foil shielded twisted pair cable. Turn the screws to fasten the

cables to the security clamps. We recommend tinning all wire ends.
