Antex electronic SX-6, SX-34, SX-5e, SX-36 user manual Files I record sound dull

Files I record sound “dull”.

1.Use a higher sample rate. Lower sample rates reduce the high frequency content, making recordings sound dull.

There is a lot of noise or hum, even when the Antex Card is idle.

1.There may be a wiring problem. Make sure the shields are grounded, especially with unbalanced connections. Don’t run cables close to hum producing equipment, such as transform- ers.

2.Don’t run unbalanced connections long distances. Generally, unbalanced is OK for less than 6 feet. (This is of course, not a hard and fast rule; your system won’t suddenly sound noisy going from 6 feet of cable to 7 feet.)

3.Make sure signal levels are matched. Set the Play sliders in the Antex Demo or Antex Mixer applications at or close to maximum for lowest noise level. Set the Trim Control to +8 rather than +20 if possible (SX-6, SX-36). Control the loud- ness with the master volume control on the mixer board or amplifier rather than using the software sliders.

Files I record sound distorted.

1.The first obvious thing to check is that the record level is not clipping; VU meters going into the red. (Occasional peaks in the red are OK.)

2.If recording from the Line Out and using the feed-through controls to adjust the record level, it is possible to overload the input to the Antex Card and still have the VU meter not go into the red. This means the signal coming into the Antex Card is
