The Blacka Acoustic TFR1502S is designed to be used with professional power amplifiers capable of producing a minimum spec of 800w – 1600 w power output into 4 ohms.

Care should be taken to avoid amplifier clipping, it is important to understand that a low power amplifier driven into clipping is more likely to damage a loud speaker than a higher power amplifier used within its ratings. Primarily because music signals have a high peak to average crest factor. When an amplifier is severely overdriven its output waveform is clipped resulting in squared off peaks and thus reducing the crest factor. In extreme cases, the waveform can approach that of a square wave. An amplifier is normally capable of producing far more power under these conditions than its undistorted rated power output. The use of very high power amplifiers with outputs greater than those recommended is discouraged.

Care should be taken to avoid switch on surges, which can result in momentary power peaks in excess of specified ratings. When powering up a sound system it is important to switch on the amplifiers after the mixer and control electronics have stabilised. When powering down the system, reverse the sequence and switch off the amplifiers first

Each connector panel has two Neutrik Speakon connectors wired in parallel. The second connector allows use of a short link lead to power a secondary parallel loudspeaker. The connectors are wired as follows:

2 Core cable

Pin 1 Positive
Pin 1 Negative

When connecting Blacka Acoustics sound reinforcement to an amplifier it is recommended that the return resistance of the cable used is less than one tenth of the normal impedance of the system or systems in parallel the chart below gives an indication of the maximum possible cable runs for conductor cross sectional areas.

The TFR1502S units can be used with a wide array of Blacka Acoustics speakers. Typical configurations are listed below

Large Bar / Nightclub : RF15 – RF215 – BS15 – BS18 – SS1000 Bass Cabinets

Portable PA: Standalone – RF15 – RF215 – BS15 – BS18 – SS1000 Bass Cabinets.


It is important that loudspeaker systems are used in a safe manner. Please take some time to review the following points concerning the use of Blacka Acoustics loudspeakers.

Professional loudspeakers are capable of producing extremely high sound levels and should be used with care. Hearing loss is cumulative and can result from levels above 90db if exposed for a long period. never stand close to loudspeakers driven at high level.

  1. TRIPOD MOUNTINGThe TFR5T can be tripod mounted with an additional rear mount bracket which incorporates a pole mounting socket to facilitate mounting on tripod stands when using stands the following precautions are advised:
    1. 1.1 Ensure that the stand will support the weight of the speaker by checking the stand manufacturers rating.

1.2 Make sure that the stand is placed on a level surface and that its legs are fully extended.

1.3 Do not place more that one speaker on each stand.

1.4 Run cables so that they do not present a trip hazard which could pull the speaker over.

1.5 When used outdoors in the wind it may be necessary to add some weight to the base of the stand.

1.6 When using a pole mount with a sub bass system observe similar precautions.



    Suspending the system should only be done by qualified personnel following safe rigging practices. Secure fixings to the buildings structure are vital. Seek help from architects, structural engineers or other specialists if in any doubt.

    The TFR5T loudspeaker enclosures are designed for installation applications and can be suspended singularly by means of the threaded inserts provided within the cabinet. The TFR5T enclosures are fitted internally with steel corner reinforcement brackets to ensure that each cabinet is strong enough to be hung from its top. Never suspend one enclosure from another to form an array or cluster using these fittings.

    The common practice of using commercially available eye bolts for suspension should only be undertaken with great caution. Eye bolts are strongest along the thread axis. Angling the enclosure will result in an angled pull and it is important to use bolts that are safe in these circumstances. Only forged shoulder eye bolts should be considered and it is important that the thread length is at least 40mm. A flat washer should be inserted between the eye bolt and the enclosure. Formed eye bolts i.e. those which are formed from steel rod bent into an eye should be avoided.
