Each output features front-panel unbalanced 1\/4” and 3.5 mm jack sockets with a rotary level control. The front-panel potentiometers adjust headphone volume from mute (fully anticlockwise) to 0 dB of gain (fully clockwise), allowing compensation for low or high Dante stream levels. For ease of installation in enclosed racks, the rear panel also provides eight parallel 1\/4” jacks.\u003c\/p\u003e\u003ch3\u003eProduct Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e8 x front panel 1\/4” \u0026amp; 3.5mm jack sockets.\u003c\/li\u003e\n\u003cli\u003e8 x parallel connections on rear panel\u003c\/li\u003e\n\u003cli\u003e8 x volume control.\u003c\/li\u003e\n\u003cli\u003eSwitch selection for each headphone output between 2 dual-channel Dante sources.\u003c\/li\u003e\n\u003cli\u003e2 x master level controls, one for each stereo Dante input.\u003c\/li\u003e\n\u003cli\u003e1 x RJ45 Dante connector (100 Mb\/s Ethernet Port).\u003c\/li\u003e\n\u003cli\u003ePoE, Link, DC and Clock LED status indicators.\u003c\/li\u003e\n\u003cli\u003eConfiguration using Dante Controller.\u003c\/li\u003e\n\u003cli\u003eAES67 operation \u0026amp; Dante Domain Manager compliant.\u003c\/li\u003e\n\u003cli\u003ePowered by PoE.\u003c\/li\u003e\n\u003cli\u003e1U 19\" rack-mount form factor.\u003c\/li\u003e\n\u003cli\u003eAluminium construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTypical Applications\u003c\/h3\u003e\u003cp\u003eA typical application is providing common headphone feeds directly from the AoIP network.

One headphone socket is on the front panel with one on the rear. The main stereo input uses electronically balanced XLR-3 connectors on the rear panel, which can be wired un-balanced. The output volume for the headphones can be controlled either by a pot situated on the front panel or a VCA signal supplied externally via the remote connector. A mono input can be mixed into the main headphone feed, for example, for mixing in talkback to the headphones. This has an input level control via a recessed adjustable potentiometer. The mono mix input can also be controlled remotely. A stereo\/mono switch is recessed on the rear panel to prevent accidental knocking. With mono selected, audio is sent to both left and right ear pieces. A LED power indicator on the front panel displays the power supply connection.

A typical application might be to provide common headphone feeds for guests in a radio studio, with a separately derived feed, perhaps including talk-back, for the presenter. The main stereo input is on XLR-3 connectors on the rear panel which are electronically balanced and can be wired unbalanced. A stereo\/mono input select switch on the rear panel sums left and right outputs to provide a mono feed to the headphones. The unit can receive an override audio signal via a jack socket for each output channel. Plugging in the jack plug will divert the headphone output from the master audio signal to the audio present on the jack plug. The override audio inputs can also be individually configured as parallel outputs of the front sockets, by setting internal jumpers. The master volume control adjusts overall level of the 6 outputs and does not affect the level of channels using the override inputs. The master volume can be disabled by internal jumpers.

Useful for connection to digital mixing desks, digital routers and matrices, the RB-DHD6 connects directly to an AES\/EBU or S\/PDIF output to provide the highest quality audio directly to the headphones. The input connectors consist of a single balanced XLR-3 for the AES\/EBU input and a single unbalanced phono connector for the S\/PDIF input. A button located on the rear panel is used to select either the AES\/EBU, or S\/PDIF, input and de-emphasis on the output can be controlled via dipswitch. If de-emphasis is selected, the RB-DHD6 will decode 50\/15µs emphasis when indicated by certain channel status bits in the incoming digital audio data. When operating, the front panel power LED flashes red and amber whenever the unit is not synchronised to the incoming digital signal.

This uses audio transformers at its input and output, providing galvanic isolation from outside interference, ensuring your communications are loud and clear, every time. In 4-wire mode, the unit acts as a 2-way intercom, with input audio routed to the headset earpiece, and microphone audio is routed to the output upon pressing the talk button. The output level is maintained at +2dBu peak level by a built-in AGC. In IFB mode, the input audio is routed to the output, and is interrupted by the microphone signal when the talk switch is pressed. The talk switch can easily be converted from momentary to latching operation to suit your application. A low battery warning LED flashes when the 9V PP3 battery has depleted to 6V, giving plenty of notice to swap the battery. In addition, the CM-BH4W automatically switches off when the headset jack is removed, and the low power circuitry gives up to 150 hours use from a single alkaline 9V PP3 battery.

The CM-BHA has an adjustable limiter to protect the listener from excessive levels indicated by a blue LED. The limiter is only enabled when an earpiece or headphones are used, and when it is activated by the toggle switch.
