RODUCT INFORMATION TG H74

Thank you for selecting the TG H74 neckworn microphone. Please take some time to read carefully through this information before using the product.

Safety Information

• Protect the microphone from moisture and sudden impacts. You could damage the microphone!
• Do not blow into the microphone, you could damage the transformer. To check the function we recommend speaking into the microphone.
• The microphone arm is rigid stainless steel tube, which must not be bent by using tools.

Application

The TG H74, which is designed for wireless operation, allow great freedom of movement.

The TG H74 with super cardioid characteristic and compensated proximity effect is particularly suitable for musical and theatre use.

Perfectly adaptable, beautifully subtle, left and right positioning, pleasingly small and robust – what more could you want from a headset microphone? Available in black and beige.

Connection

The TG H74 provides a female 4-pin mini XLR connector and is available in two versions:

as Opus version it can be connected to beltpack transmitters of the wireless Opus 600 and Opus 910 microphone systems; as TG version it is used with the wireless TG 1000 microphone system.

For wired applications with phantom power sources the TG H74 must be used with an optional power adapter. If the

TG H74 is directly connected to phantom power, the microphone can be damaged!

How to use the Microphone

The TG H74 eleminates background noise to a large extent due to the supercardioid polar pattern. In order to achieve a high gain-before-feedback, position the microphone capsule as close as possible to the corner of the mouth. Use the supplied WS 54 wind shield to avoid “popping” noise.

The flexible neckband of the TG H74 can be adapted optimally to almost every head size and shape and is also

suitable when wearing spectacles. Make sure that the rigid microphone arm is never bent by using tools! The rotatable and slideable microphone arm allows positioning the microphone next to the mouth.

The microphone can be worn on the right or left hand side. Attach the microphone arm to the appropriate microphone and cable holder. For transport purposes, the headset can be collapsed and folded inwards.

Maintenance

Use a soft, damp cloth for cleaning the TG H74 microphone and connecting cable. If necessary, you can use a gentle cleansing agent (such as washing-up liquid). Make sure not to allow any water to enter the microphone capsule and never use any solvent cleansers.

The supplied pop shield should regularly be removed from the microphone capsule and cleaned in clear water. Make sure the pop shield is completely dry before it is replaced back onto the microphone.

Service

Servicing must be carried out by qualified service personnel only. Dismantling the microphone yourself will invalidate the guarantee.

Disposal

This symbol on the product, in the instructions or on the packaging means that your electrical and electronic equipment should be disposed at the end of its life separately from your household waste. There are separate collection systems for recycling in the EU. For more information, please contact the local authority or your retailer where you purchased the product.
