DA-410. Our dilated experience in the design and manufacture of effect processing equipment, had led to us to carry out this distribution amplifier/zone mixer/mic splitter of great performances. There is a lot the characteristics that make of the ALTAIR DA-410, one of the most highlighted of the audio professional market, here enumerated some: The ALTAIR DA-410 is a high performance distribution amplifier/zone mixer/mic splitter, compact, only one rack 19"...
2. SWITCHES, CONTROLS, ADJUSTMENTS AND CONNECTORS These are the switches, controls, adjustments and connectors that you could find in your ALTAIR distribution amplifier/zone mixer/mic splitter. The description and explanation of each one of them, you will find in the corresponding section.

It is always advisable to mount the unit in rack, either for mobile or fixed installations, for protection, safety, aesthetics, etc. The ALTAIR DA-410 is designed for standard 19" rack mounting, and occupy 1u high rack space. CHANGING THE VOLTAGE The distribution amplifier/zone mixer/mic splitter unit is set to operate at 230V, 50-60Hz and at 115V, 50-60Hz.
DISTRIBUTION AMPLIFIER/ZONE MIXER/MIC SPLITTER DA-410. Distribution amplifier/zone mixer/mic splitter set up to 230 V. Distribution amplifier/zone mixer/mic splitter set up to 115 V. Make sure that the fuse is the right one for the selected voltage: FUSE (230V. 50-60 Hz) FUSE (115V. 50-60 Hz) T0,5A.
DISTRIBUTION AMPLIFIER/ZONE MIXER/MIC SPLITTER DA-410. CONNECTING TO THE MAINS The connection of the distribution amplifier/zone mixer/mic splitter power supply to the mains takes place by a standard cord included in the box. Make sure that the unit power switch is at 0 position (turned off).
DISTRIBUTION AMPLIFIER/ZONE MIXER/MIC SPLITTER DA-410. UNBALANCED INPUT: This type of connection will be used when the sound source doesn't provide balanced output. When possible, employ the connection type 1. 1) Using twin-lead shielded cable: 2) Using single conductor shielded cable:...
DISTRIBUTION AMPLIFIER/ZONE MIXER/MIC SPLITTER DA-410. BALANCED INPUT: OUTPUT CONNECTION The distribution amplifier/zone mixer/mic splitter output signal is carried out through ten XLR- 3-32 male connectors, two per stereo channel. The outputs are balanced, with a nominal impedance of 100 Ω. The next list shows the input pins correspondence as A.E.S recommendation...
DISTRIBUTION AMPLIFIER/ZONE MIXER/MIC SPLITTER DA-410. UNBALANCED OUTPUT: This type of connection will be used when the sound destination unit doesn't provide a balanced input. When possible, employ the connection type 1. 1) Using twin-lead shielded cable: 2) Using single conductor shielded cable:...
DISTRIBUTION AMPLIFIER/ZONE MIXER/MIC SPLITTER DA-410. BALANCED OUTPUT: GROUND LINK In some installations, it might be necessary to isolate the distribution amplifier/zone mixer/mic splitter electric ground, from the system mains earth, in order to avoid ground loops that could generate unwanted noises. For this reason, the unit provides an EARTH-LINK switch placed at the rear panel in order to lift the mains earth from the unit.
Mono operation is similar. Exceptions are detailed separately when necessary. TURN ON DELAY CIRCUIT The ALTAIR DA-410 incorporates a delay circuit, consisting of a relay, which protects the output signal from switch-on transients. This delay takes two seconds, and in the meantime the unit remains in mute.
DISTRIBUTION AMPLIFIER/ZONE MIXER/MIC SPLITTER DA-410. This multipoint level circuit indicates the highest level reached inside the unit output circuits and warns the operator about possible problems. When the level indicator lights green, the internal level has reached -20 dBv. (signal present led). Should any internal level is near overload (+15 dBv) the level indicator lights on red to warn the security limit has been surpassed.
Nominal gain is 0 dB when line mode and +12 dB when configured as Mic. Due to the reduced gain (+12 dB) in MIC mode, the DA-410 output signals must be externally connected to preamplifiers or mixers into its MIC inputs.
DISTRIBUTION AMPLIFIER/ZONE MIXER/MIC SPLITTER DA-410. The MIC mode is not intended as a microphone preamplifier. Instead, it accommodates or adapts microphone impedances to the unit allowing perfect match between microphones and long run cabling to external mixers. This reduced gain, is optimised to use the unit as audio SPLITTER: If the input and output level...
DISTRIBUTION AMPLIFIER/ZONE MIXER/MIC SPLITTER DA-410. mixer/mic splitter is cheaper than utilise a graphic equaliser, and also avoids unwanted manipulations. The optional equaliser card provides a full parametric equalisation point. It means, you can arbitrary choose and set-up the equalisation points parameters: gain, bandwidth and centre frequency.

DISTRIBUTION AMPLIFIER/ZONE MIXER/MIC SPLITTER DA-410. INPUT TRANSFORMER (IT-DA) In order to improve the input common mode rejection ratio and for a galvanic isolation with the previous part of the audio system, it is available an input transformer. Each XLR-3-31 input has an insert point for the input transformer; therefore, you could mount four input transformers in the unit.

It is important notice to install the jumper in the appropriate location, because placing it in the wrong location could cause a short circuit in the power supply or additional malfunctions in the unit.

(refer the section INPUT CONNECTION for more information), it is necessary to lift the input ground. In order to don't modify the cable, the DA-410 has jumpers that open the input grounds. With the jumper placed, the ground is close, and with the jumper removed, the ground is lifted (in order to don't lose the jumper, it could be placed attached over one of the two pins).

Following the signal is electronically unbalanced and crosses the input level control. Note that the input level detector reference signal is measured in two points. It's measured before and after the input level control, in order to know if the input signal is overloaded before the DA-410 input or in the input amplifier.
The output console output and the redundant system if needed, drives the DA-410 inputs. In this case, we configure the inputs in LINE mode operation. The distribution amplifier then buffers the selected signal A or B to each one of the televisions and/or radio stations separately.
The input signals to the DA-410 come from a mixer console (in order to control the microphones for example) and a cassette desk (or a CD) both working in stereo mode.
In the mic splitter example application, we have supposed a live show, in which we should give signal to a recording truck. For explanation simplicity, we supposed a reduced set-up about four microphones and a DA-410 only. Normal set-ups will need 32 or more microphone inputs corresponding to 8 or more DA-410 units.
