Please follow these tips before calling the Sonic

Devices hotline for assistance:

) Read and review all sections and follow all instructions in this

manual.

2) Before terminating speakers to SPKR1 (J3-Right) + SPKR2 (J4-

Left), verify that all wiring is free from shorts, opens, crosses or

ground problems. Please verify polarity of speaker wiring (+/-).

3) After connecting power supply (J5); verify that LED’s have lit on

the front HB card panels and backplane in J1 and J2 positions for

both HNB-A and HNB-B (Green LED). If there is no power LED

light on HNB-B; verify wiring in the RJ45 to meet EIA-568B per

section 4.7 and 4.8 (power on pins 3+6). If there is no light and AC

power source is confirmed; verify that polarity (+/-) wiring is correct

with Red or Ribbed wire as (+) positive. Use front panel soft button

and IR remote control to cycle power On/Off.

4) If no Override page is heard and input audio sources are not

muted during “master-override” page; verify wiring termination

polarity (+/-) to the MO connector and insure ‘Volt Sens’ POT on

rear is adjusted correctly and front MO-IN ‘orange’ LED lights.

5) If after power and system terminations have been made and no

audio is detected, insure volume gains are adjusted properly and

that all speakers are of the proper impedance and/or have correct

impedance-matching transformers (25V or 70V / see HNB-70V2X

section 5.2) installed.

6) If after power, speakers and audio sources are properly con-

nected and no audio is heard over the speakers please insure

the HB-2PA Preamp front slide switch is located in the correct

position (A,B,C) corresponding to the audio source input (A =

internal dockable connector, B = 3.5mm front jack, C = RCA

front jacks).

7) If audio level is low or lower than expected, please check the HB-

2PA Preamp card (in HNB-A or HNB-B) and insure the JP1 and

JP2 jumpers are in the proper position: JPI + JP2 terminated

(both terminals) when NO HNB-C wireless is connected to the

HNB-A or when HNB-C is connected to HNB-A, both jumpers

should be removed or only terminated on one pin. Proceed to

normal volume audio adjustments.

8) If video signal / picture does not appear at AV projector, please

verify LED’s are “on” (Green) at the HB-VTx front panel and HB-

VRx receiver which includes power and signal (see section 6.3 to

6.6). Insure all CAT5e/RJ454 terminations meet EIA-568B (sec-

tion 4.7 and 4.8) and terminations of VGA, S-video and Composite

video are made properly at the AV projector. Finally, insure the AV

Projector and source are transmitting and set to compatible source

and resolution (see section 6.6). NOTE: Image quality such as;

Color, Brightness, Focus, Blurring are most likely adjustments in

the projector, computer and or video source.

9) It the HB-IRRC remote control does not function please check the

AAA batteries (x2) to insure a full charge. Also check to insure

direct sunlight or strong florescent lights are not interfering.

Reminder: The IR remote control will not operate beyond (50) feet.

10) If any of the HNB‐C RF microphones or receivers experience

intermittent noise or drop out please check to insure batteries

are charged. Please remember HNB‐C RF coverage is

designed to perform without interruption or problem within a 40'

x 40' x 10' (typical) room space and may work well beyond this

depending on room architecture, construction and line of sight.

11) If any of the HNB‐C RF microphones or receivers do not show

connection or have continuous flashing Blue LED please insure

units are properly 'paired' (refer to sections 7.1 to 7.6).

12) If after successful HNB-C wireless install and both TM Teacher

Microphones and SM1 Student Hand held microphone are con-

firmed to be performing properly (without noise, drop out with

acceptable coverage throughout the room) and then after

installing the HB-Tx transmit module in the RIGHT SLOT of

HNB-C with corresponding HB-RU receiver/headphones you

now notice intermittent noise or drop out of the microphones

please refer to section 7.8 and follow the procedure changing

the ID Frequency of the HB-Tx / HB-RU units. After following

this procedure all wireless microphones should return to normal

operation.

13) If after installing the HNB-C wireless unit with the HB-Tx card

and you notice the SM1 hand-held microphone is not transmit-

ting audio to the HNB-A overhead connected speakers please

check to insure the front panel slide switch on the HB-Tx mod-

ule is in the 'UP' position for Normal Broadcast mode. Once

you move the slide switch to 'Normal Broadcast' the SM1 micro-

phone will be heard over the room speakers.

14) If you continue to experience difficulty, please call SonicDevices
