Safety instructions

Intended use

This device amplifies electric audio frequency signals to operate passive speakers. Use the device only as described in this user manual. Any other use or use under other operating con‐ ditions is considered to be improper and may result in personal injury or property damage. No liability will be assumed for damages resulting from improper use. This device may be used only by persons with sufficient physical, sensorial, and intellectual abilities and having corresponding knowledge and experience. Other persons may use this device only if they are supervised or instructed by a person who is responsible for their safety.

Safety
DANGER!
Danger for children
Ensure that plastic bags, packaging, etc. are disposed of properly and are not within reach of babies and young children. Choking hazard! Ensure that children do not detach any small parts (e.g. knobs or the like) from the unit. They could swallow the pieces and choke! Never let children unattended use electrical devices.

DANGER!
Electric shock caused by high voltages inside
Within the device there are areas where high voltages may be present. Never remove any covers. There are no user-serviceable parts inside. Do not use the device if covers, protectors or optical components are missing or damaged.

NOTICE!
Power supply
Before connecting the device, ensure that the input voltage (AC outlet) matches the voltage rating of the device and that the AC outlet is protected by a residual current circuit breaker. Failure to do so could result in damage to the device and possibly injure the user. Unplug the device before electrical storms occur and when it is unused for long periods of time to reduce the risk of electric shock or fire.

NOTICE!
Magnetic fields
The device generates strong magnetic fields that can interfere with the function of poorly shielded devices. The strongest magnetic fields are directly above and below the power amplifier. Therefore, never place sensitive devices such as pre-amplifiers, radio trans‐ mission systems, or tape decks directly above or below the power amplifier. When installing the power amplifier into a rack, you should place it in the lowest position, and further equipment such as pre-amplifiers in the highest position.

NOTICE!
Possible staining
The plasticiser contained in the rubber feet of this product may possibly react with the coating of your surface and after some time cause permanent dark stains. In case of doubt, do not put the rubber feet directly on the surface and use a suitable underlay if neces‐ sary, i.e. felt pads or similar.

Installation and starting up

NOTICE!
Possible staining
The plasticiser contained in the rubber feet of this product may possibly react
with the coating of your surface and after some time cause permanent dark stains. In case of doubt, do not put the rubber feet directly on the surface and use a suit‐ able underlay if necessary, i.e. felt pads or similar.
Unpack and check carefully there is no transportation damage before using the unit. Keep the equipment packaging. To fully protect the product against vibration, dust and moisture during transportation or storage use the original packaging or your own packaging material suitable for transport or storage, respectively. Create all connections while the device is off. Use the shortest possible high-quality cables for all connections. Take care when running the cables to prevent tripping hazards.

Connections and controls

Front panel TSA 1400, 2200

1. [POWER] | mains switch to turn the device on and off

2. Indicator LEDs [CH-A], [CH-B] | These LEDs indicate the ready status of the device ([Power]), the input signal level ([Signal] / [–20] / [–15] / [–10] / [–5]), channel overdrive ([Clip]) and a fault condition ([Fault]).

3. [CH-A], [CH-B] | input gain controls for channels A and B
   Rear panel TSA 1400220
   

4. IEC chassis plug for the power supply

5. OUTPUT CH-A], [OUTPUT CH-B] | signal outputs, designed as lockable NL4 chassis socket to connect speakers

6. 9 [INPUT CH-A], [INPUT CH-B] | signal input channels, designed as XLR socket pair (input / output) to loop the audio signal to other devices

7. [Stereo | Bridge] push-button | switch for operating modes ‘Stereo’ (channels operate independently of each other) and ‘Bridge’ (two channels are interconnected to form one channel with double output)

8. [Lift | Ground] selector switch Use the Ground / Lift switch to separate the connection between the earth pin of the device and the unit’s signal ground to prevent ground loops:

   • ‘Lift’ position (not pressed): no connection
   • ‘Ground’ position (pressed): earth pin and signal ground are electrically connected

Plug and connection assignment

Introduction
This chapter will help you select the right cables and plugs to connect your valuable equip‐ ment in such a way that a perfect sound experience is ensured. Please note these advices, because especially in ‘Sound & Light’ caution is indicated: Even if a plug fits into the socket, an incorrect connection may result in a destroyed power amp, a short circuit or ‘just’ in poor transmission quality!

Balanced and unbalanced transmission
Unbalanced transmission is mainly used in semi-professional environment and in hifi use. Instrument cables with two conductors (one core plus shielding) are typical representatives of the unbalanced transmission. One conductor is ground and shielding while the signal is trans‐ mitted through the core. Unbalanced transmission is susceptible to electromagnetic interference, especially at low levels, such as microphone signals and when using long cables. In a professional environment, therefore, the balanced transmission is preferred, because this enables an undisturbed transmission of signals over long distances. In addition to the conduc‐ tors ‘Ground’ and ‘Signal’, in a balanced transmission a second core is added. This also transfers the signal, but phase-shifted by 180°. Since the interference affects both cores equally, by subtracting the phase-shifted signals, the interfering signal is completely neutralized. The result is a pure signal without any noise interference.

Cleaning

Fan grids
The fan grids of the device must be cleaned of any contamination, such as dust, etc. on a reg‐ ular basis. Before cleaning, switch off the device and disconnect mains-operated devices from the mains. Only use pH-neutral, solvent-free and non-abrasive cleaning agents. Clean the unit with a slightly damp lint-free cloth
