Telex RTS 2-Channel Portable Beltpack Communications Kit with Single-Sided Headset

Styled in black, the Telex RTS BP-325 is a 2-channel portable beltpack station designed to work in conjunction with RTS Two-Wire intercom systems and the appropriate, dynamic headset mic. It facilitates conversations across the air-waves in one of two fashions: you can either hold down the Talk button—which instantiates momentary mode, allowing you to remain inaudible when you're not pressing the button—or, conversely, tap the Talk button a few times, which will occasion the mechanism to latch into an ever-on position. Be advised, if you instantiate latching mode, everything you say will be heard until such time as you turn it off. 

This unit also sports the ability to send out a call signal, should you need page someone on one of the two provided channels. Likewise, you might also find yourself paged; in this case, the red call LED will flash, presenting you with the opportunity to speak with the person courting your attention.

The RTS BP-325 also features a sidetone adjustment control for changing the level of your own voice in your discrete pair of headphones whilst talking. The unit supports mono and stereo headsets, and there's also a separate connector for monaural carbon-mic headsets. Furthermore, the RTS BP-325 sports the ability to generate an inaudible signal which can effectively "kill" the ongoing signals of unattended intercom stations.  

Designed for wired and wireless communications alike, the Senal SMH-1010CH is a single-sided communications headset for use in TV or radio broadcast settings, as well as sports applications and behind-the-scenes theater environments. First, you'll notice its deep, padded ear cushion, which offers not only comfort, but isolation and noise-reduction in noisy scenarios. Behind the ear cushion, a 40mm neodymium driver gives you a wide frequency response of 20 Hz to 20 kHz, as well as an expansive dynamic range.

The microphone supplied with the SMH-1010CH is a cardioid dynamic capsule, designed to minimize pickup of off-axis sound while capturing your voice clearly and intelligibly. It sits upon a durable gooseneck that can be rotated 180°. This configuration can be used on the left or right side of the SMH-1010CH. Additionally, a switch is built into the gooseneck that automatically mutes the signal when it's swiveled into the vertical position; thus, to mute your microphone, all you have to do is flip the gooseneck into the upright position. 

The SMH-1010CH interfaces with a variety of cables that offer compatibility with many major wired and wireless systems, such as Telex and PortaCom. You can also use this communication headset with broadcast consoles, mixers, and computers. Simply plug your separately-available, corresponding cable into the SMH-1010CH's twist-locking jack, and you're good to go. The headphones are also collapsible, making storage and transportation a cinch.

The Senal SMH-H5X is a replacement cable intended for use with SMH-series communication headsets. It can also be used to augment your headset's versatility, giving you the ability to plug into a Telex system if you already have cabling for a different broadcast console or mixer on hand.

At one end, you'll find the 3.5mm TRRS connector and corresponding locking jack. This twists into your SMH-1010CH or SMH-1020CH communication headset, establishing a secure and reliable connection all the while.

At the other end, you'll note a male, 5-pin XLR connector that allows you to quickly connect the headset to Telex systems. In fact, the SMH-H5X is part of a whole ecosystem of SMH-series cables, all of which let you swap between the pin-outs of different communication and broadcast systems with ease.

The black Kopul Premium Performance 3000 Series XLR Male to XLR Female Microphone Cable (20') is designed to be an extremely quiet and flexible cable that is ideal for the most demanding live sound and performance applications. The cable is engineered to be durable and provide protection against EMI, RFI, and static noise. While the cable's color-coding affords the ability to quickly differentiate between multiple connections on stage, it provides a pleasant aesthetic quality at the same time.

Premium Performance 3000 Series cables are made from 24-AWG OFC copper wire that's wrapped with PE insulation and a conductive PVC inner shield. A cotton-yarn inner layer helps reduce electrostatic and microphonic noise. The 95% dual-spiral shielding makes the cable resistant to EMI and RFI noise. The Neutrik XX silver connectors provide a high level of connectivity, and all the solder connections are shrink-wrapped for protection.
