The all-new ST-300 base transmitter includes digital channel controls, a backlit LCD display, front control of input levels and RF transmission level, and a headphone monitoring jack. Users can select from 17 narrow band channels. Another new feature for use with the SR-400 receivers is Enhanced Dynamic Range (E.D.R.), an option that can be turned on or off from the front panel. E.D.R. compands the audio program for better signal to noise ratios and improved dynamic range. The all-new SR-400 portable receiver includes a backlit LCD channel display, E.D.R. capability, one on/off volume control and a high frequency boost for increased clarity. The SR-400 has 17 selectable channels and runs on two AA batteries. The all-new PST-170 portable transmitter includes a backlit LCD channel display, E.D.R. capability, input gain-adjust, and an auxiliary input for recorded messages. The PST-170 can transmit on any of the 17 SoundMate channels and runs on two AA batteries.
The SR-50 remains a cost effective rugged portable receiver with one on/off volume control and two AA battery operation. The SR-50 also has a new look, with new contours and a modern black plastic shell. The SR-50 single channel receiver is available in any of the 17 SoundMate channels and can run over 30 hours on two AA alkaline batteries. The SR-400, PST-170 and SR-50 are all compatible with the BC-100 drop in recharger, for use with NiCd or NiMH batteries. The new SoundMate components are available in the following convenient systems: the SM-2, SMP-2 and SMP-400. The SM-2 includes one ST-300 base transmitter, four SR-50 receivers, four SEB-1 earbuds and a SoundMate wall plaque. The SMP-2 is designed for portable tour applications and includes one PST-170, a headworn microphone, six SR-50 receivers and six headphones, all in a deluxe carrying case. The SMP-400 is an extremely flexible tour system with four SR-400 receivers in place of the SR-50’s.
TELEX SM2 FAQs
Question: Are the new SoundMate Products compatible with the product I already have?
Answer: Yes, the new generation SoundMate products (ST-300, SR-400 and PST-170) are direct replacements for the existing products (ST-200, SR-100, and PST-16). The channels are the same and they are completely compatible with the older products. The bodypacks are also compatible with the current BC-100 battery charger.
Question: What is E.D.R. and how does it work?
Answer: E.D.R. stands for Enhanced Dynamic Range and this feature is available on the ST-300, PST-170 and SR-400. E.D.R. lowers the noise level and improves intelligibility for users by using a circuit called a compander. A compander COMPresses the signal in the transmitter and then exPANDs the signal in the receiver. Companding the signal results in larger signal levels compared to the noise floor. The E.D.R. function must be engaged in the transmitter and SR-400 receiver for proper operation.
Question: What does the function do on the SR-400?
Answer: The treble clef symbol ( ) represents the high frequency boost function. Most people with moderate hearing loss have more loss in the high frequencies than the low and that the high frequencies contain much of the important content for understandable speech. By engaging the HF boost, the SR-400 circuit raises the level of the high frequencies which lets the user hear better at a more comfortable overall volume.
Question: How do you adjust the audio input for the ST-300 with no switches or adjustments on the back panel?
Answer: The inputs can all be adjusted electronically from the front panel controls. Once you hit the SET button, all of the audio settings will appear in the right half of the LCD display. By pressing SET, the focus changes and the feature will flash, while it is flashing the UP and DOWN buttons can be used to turn the input off, adjust the attenuation, or select the balanced level input type (Mic, 600Ohm Line, or 70V line levels).
Question: How does it compare to the competitive product?
Answer: The new Generation SoundMate compares favorably in feature and price with the rest of the products in the market.
Question: Can I use Nickel Metal Hydride (NiMH) rechargeable batteries?
Answer: Yes, the BC-100 and all of the bodypacks are compatible with NiMH rechargeable batteries. In fact you will get twice the battery life with NiMH than with NiCd.
Question: How many SoundMate Channels can be used in one place at one time?
Answer: Under ideal conditions and using Normal RF transmit power, you should be able to use 8 different channels at once. Of course, building construction, location, and other interference sources can limit the number of systems and every application is slightly different.
Question: How many receivers do I need for a 500-seat church or theater.
Answer: The American Disabilities Act (ADA) recommends providing 4% of the total seats but 5% is easier to figure. For a 500-seat venue you should have 25 receivers as a minimum.
Question: Where should the ST-300 base transmitter be located?
Answer: Select a suitable location for the ST-300 transmitter that will allow accessibility to a 110 volt AC power outlet and within reasonable cable length (see table) to the program source. This location should also be in the same room as the 300 – 1500 foot transmission range where the receivers will be used. (If there is a conflict with these requirements see the Antenna Section). If the transmitter is mounted on a tabletop or counter (non-rack-mounted), allow for plenty of free space around the unit that is away from metallic structures and room to extend the rear-mounted antenna. If the ST-300 is rack mounted, it will require an external antenna (HGA-1) and a single (RM-S) or dual (RM-D) rack mount hardware kits. Mount the transmitter away from wireless microphone receivers, CD and DVD players, and computers that may cause noise and interference.
Question: Is there rack mount hardware available for the ST-300?
Answer: Yes, the ST-300 can be used with the RM-S rack mount kit. When rack mounting the transmitter, mount it away from other sensitive receivers and use an HGA-1 remote mount antenna to get the best performance.
Question: Can I use both audio inputs on the ST-300?
Answer: Yes, both audio inputs can be used at the same time. Use the input controls and the LCD display to mix the two inputs. The PST-170 also has a secondary audio input for mixing in tape play back or other previously recorded tour information.
Question: How many SR-50 or SR-400 receivers can be used in one place?
Answer: The number of receivers on one channel is unlimited. Think of the ST-300 or PST-170 as a small FM radio station, it broadcasts the signal and it doesn’t matter how many receivers are out in the broadcast area.
Question: Does this mean the ST-200, SR-100 and PST-16 products are obsolete?
Answer: Yes, these products are directly replaced by the ST-300, SR-400 and PST-170. Telex will continue to service and support all of these products in field for the full 3-year warranty period and beyond.
