transformer attenuators circuit TL10-RE:

These attenuators enable the sound level in a room to be adjusted by attenuating the sound performance of the speaker units with a transformer in constant-voltage systems (100, 70, 50 V). Each attenuator has an autotransformer, an 11-position switch (10 positions + Off) and front masks. They are available with different output powers, depending on the load that can be connected to them.

Each model (TL10-RE, TL30-RE and TL60-RE) has a by-pass relay able to exclude the attenuator in case of an alarm and/or emergency signal having priority (activation of the relay with a 24 VDC current on an additional two-pole line). They can be easily flush-mounted on a wall using the AC911 box or secured to a wall using the AC913 adaptor.

shure slx wireless systems:

Wireless system offers easy set-up and high audio quality for virtually any application. Features include Automatic Frequency Selection, Automatic Transmitter Set-Up, Predictive Diversity technology, and removable antennas with rack hardware.

Frequency Band Selection

Most countries closely regulate the radio frequencies used in the transmission of wireless Infor mation. These regulations state which devices can use which frequencies, and help to limit the amount of RF (radio frequency) interference in all wireless communications. To be flexible enough to operate worldwide, SLX receivers are available in a number of models, each with a unique frequency range. Each frequency range, or band, spans up to 24 MHz of the

wireless broadcast spectrum.

To facilitate system setup and protect against RF interference, each system comes with multiple predefined frequency groups and channels.

When using a single SLX system, the operating frequency will generally not have to be changed. In an installation with multiple receiver/transmitter systems, each system must operate on a sepa rate channel. The group and channel system provides an optimum frequency spread when using multiple systems.

Within a single frequency band, up to 12 individual transmitter/receiver systems may be used in a single installation. In regions where additional frequency bands are available, it is possible to operate up to 20 systems simultaneously. Check with your local Shure retailer for information on which bands are available in your area

shure slx wireless systems instructions:

Single System Setup
Follow these steps when using a single SLX system : Automatic Frequency Selection Scans for an available channel and sets the receiver to that channel . Automatic Transmitter Setup
1. Turn On the transmitter.
2. Open the transmitter battery compartment to display the infrared ( IR ) port
3. With the IR port exposed to the receiver , press sync .
4. Hold the sync button until the red light stops flashing on both receiver and transmitter .
5. When the receiver ready light glows , the system is ready for use .
6. Close the transmitter battery compartment .

BS-1015BSW

Description
Type: Headset with a streamlined design and white color.

Operation at 100V: 15 watts, 10 watts, or 5 watts.

Operation at 70V: 7.5 watts, 5 watts, or 2.5 watts.

The BS-1030 is a small, 2-way bass-reflex type
speaker featuring a wide frequency range suitable
for use for announcements and music playback. The
BS-1030B can be used for both high-impedance and
low-impedance applications. The speaker’s splashproof construction permits it to be installed under the
eaves where the speaker is not directly exposed to rain.

BS-633A

Description

Speaker Type: 6-watt speakers with a streamlined design, ideal for mounting on concrete ceilings or walls.

Installation: Suitable for both ceilings and walls.

Operation at 100V: 6 watts, 3 watts, or 1 watt.

Operation at 70V: 3 watts, 1.5 watts, or 0.5 watts.

The BS-678, of which cabinet is made of wood, can be installed in a vertical or horizontal orientation. Either concealed in-wall wiring or exposed wiring can be used for speaker cable connection. The speaker structure that permits direct wall-mounting with screws prevents the speaker from falling easily even if an outward force is applied to. The input impedance can be easily changed by changing the tap position of the transformer.
