User manual FURMAN HRM16

[. . . ] The HRM-16 user presses their TALK button to speak to all other HRM-16's and the HDS-16. This mode enables discussion between the musicians and mix engineer between takes. Turn to page 5 to see how to change modes. A solo system allows the engineer to auto- 1 HDS-16/HRM-16 HEADPHONE DISTRIBUTION SYSTEM matically mute all HRM-16 sends except the channel D stereo and talkback outputs. [. . . ] You will see the left- level controls. The HDS-16 solo feature requires patching the mix console's main or mix output to the HDS-16's channel D input. Note: After using the solo feature to listen to the main console mix between takes, turn the channel D level control off (to 0) on all HRM-16s before resuming recording. It is easy to forget to turn down channel D because you will still hear the intended channel mix but the main console mix will also be present. Figure 4: Detail of HDS-16 front panel: ¼-inch inputs and Solo interface front corner of the main PCB. Lift the jumper from the J-2 two-pin header and move it to J-1 to change the talkback mode from Live/Stage to Studio mode. Figure 4 shows the solo interface, labeled CHANNEL D LEFT & RIGHT ONLY because all HRM-16 outputs are muted when the SOLO button is depressed except Channel D. A switch can be plugged into the ¼-inch SOLO REMOTE SWITCH connector to turn the solo function on/off. The SOLO ON LED indicator lights when the solo function is active. SOLO This feature allows musicians at the HRM-16s to hear rough and final mixes or soloed tracks from the recording console without exiting to control room or manually altering the HRM-16's Figure 5: HDS-16 rear panel 5 HDS-16/HRM-16 HEADPHONE DISTRIBUTION SYSTEM Note: The remote and front panel switches are wired in parallel. Although either switch can activate the SOLO function, both must be in the off position to deactivate it. See Table 1 on page 8 for information about cable losses beyond 100 ft. REAR PANEL Push the AC-power switch up to the ON position to power the HDS-16. The GROUND lift switch has two positions: LIFT: Signal ground is separate from chassis ground. Earth ground (AC line cord) is connected to the chassis only. GROUNDED: Signal ground is connected to chassis ground; use this setting unless there is hum or noise present. Note: Be sure all units are turned off before connecting an HDS-16 to one or more HRM-16's. The HDS-16 rear panel has six, 50-pin, Centronics output connectors for the HRM-16s, AC-power, and ground switches (Figure 5). While male-to-male Centronics cables are available from computer retailers, Furman manufactures superior quality cables with twisted pair construction to optimize sound quality and reject cross-talk interference. We highly recommend using the 25 twisted pair, shielded, 25-ft cable supplied with each HRM16. Contact Furman for other cable lengths and linking adapters. Note: The maximum recommended cable run Figure 6: HRM-16 top panel 6 HDS-16/HRM-16 HEADPHONE DISTRIBUTION SYSTEM HRM-16 REMOTE MIXER The HRM-16s receive their input signals and power supply entirely through the Centronics cable from the HDS-16. Eight mono and four stereo channels can be mixed and monitored with headphones or sent to a monitor system. The eight mono channels may be routed to the EFFECTS SEND output on the rear panel. The effected signal is returned to the HRM-16 through the stereo effect returns on the rear panel and blended into the mix with the EFFECTS RETURN level control. The HRM-16 can be easily mounted on a microphone stand with the thumb screws and clip provided, or placed on a table or shelf. TALKBACK VOLUME control, TALK button, and built-in microphone; EFFECTS RETURN level control. TALKBACK Press the TALK button and speak in the direction of the built-in microphone above the button (three small holes in the shape of a triangle). The microphone will pick up voices from up to six ft away so you do not need to speak directly into it. Use the TALKBACK VOLUME control to alter the level of incoming talkback information. See page 4 for a complete description of the talkback functions. REAR PANEL TOP PANEL The top panel provides: Level controls for four STEREO SOURCES; EFFECTS SEND, L/R pan, and level controls for each of eight mono channels; MASTER volume control; HI and LO shelving EQ controls with 12 dB boost and cut; The HDS-16/HRM-16 system can be connected in parallel or series without compromising sound quality or power as long as no more than four HRM-16s are connected in series from a single HDS-16 output. Parallel: Each HRM-16 is connected directly to the HDS-16 in a star configuration. Series: One HRM-16 is connected directly to the HDS-16 with additional HRM-16's connected together in a daisy chain. Two, 50-pin, Centronics connectors are located on the right of the HRM-16's rear panel: Figure 7: HRM-16 rear panel 7 HDS-16/HRM-16 HEADPHONE DISTRIBUTION SYSTEM INPUT FROM HDS-16 This connector delivers the input signals and power supply from the HDS-16 (parallel) or from another HRM-16's OUTPUT TO ADDITIONAL HRM-16's connector (series).
