Sound Quality - SABINE SWM7000 Application And Troubleshooting Manual

Shifting Receivers
(Requires firmware version 2.88 or higher, and software version 2.23 or higher)
•
Use the software to make the change in the receivers. With the receiver
connected to your computer and the SWM7000 Remote Software running, hit Alt-
C and then type the following when asked for a password:
o For F0 (down-shifted) type: chanlo
o For F1 (standard) type : channormal
o For F2: (up-shifted) type: chanhi
•
A minus sign (-) will precede the channel number on the receiver and the
software if the frequency is shifted down (F0), and a plus sign (+) will show if the
frequency is shifted up.
Important note: Both the transmitters and receivers must be shifted together. Down-
shifted channel 44 corresponds to normal channel 1. Anything below channel 44 is out
of the license-free zone. Channel 44 and above are still inside the license-free zone. It
is important to note that some receivers will not operate reliably below channel 15. We
recommend channels 20 through 40 for testing.
Up-shifted channel 42 corresponds to normal channel 70. Selecting any channel above
42 takes you out of the license-free band. Channel 42 and below are still in the license-
free zone. We recommend temporarily using channels 50 through 65 for testing.
Note: When shifting a receiver, start by choose a channel within the area you are
shifting to.

3. Sound Quality

3.1. If your SWM7000 system does not sound as good as a wired mic, something is out
of adjustment. The first thing to try is to plug a wired mic into the receiver's audio-out
cord. If the system still sounds bad, your problem is downstream of the receiver.
Check your other equipment. Try bypassing your EQ first, then the compressor, etc.
3.2. If the problem is definitely with the SMW7000, bypass all functions to identify the
cause. Bypass the FBX, set the compressor ratio to 1:1, set the de-esser to 0, set the
mic model to NONE, set the output level to -10dB, or simply load the System Default
program. If the system sounds better, first try resetting the FBX. Then add the other
functions in one at a time until you find the function that is out of adjustment.
3.3. The default PAD setting on the transmitter may be too high for loud programs or very
hot belt-pack mics. This will cause clipping and distortion. If so, open the case,
press select until the pad blinks and use the down arrow to set a deeper pad setting.
Pad settings range from 0 (no pad) to -40 dB (recommended for high-output mics such
as the Voice Technologies SVT70 series available from Sabine).
3.4. Two mics on the same channel If you turn on a mic and it screeches and sounds
grossly distorted, there is probably another mic on that some channel within 100
meters. Turn off the other mic or change channels.
