5 � Channel modules : Module setup
The maximum delay time is 16383 samples, at every sampling frequency. In milliseconds, this equates to:
FS 44.1 Maximum delay (ms) 371.5

edited is linked to another channel, as well as to whether the project is a stereo or surround project. The POD 4 encoder is used to set the pan or balance. Beside the on-screen representation of this control is a CENTER button. Use this to center the pan or balance setting easily. In the �normal� (unlinked, stereo) case, the oddnumbered (left) panpot of a pair of channels can be ganged together with the even-numbered (right) panpot. Use the on-screen GANG button to link the panpots of the channels in this way. A linked pair of channel modules has the pan control of a mono channel replaced by a balance control. In the case of such a control, no ganging of control is possible, but two other controls are provided. The �rst, controlled by the POD 2 encoder, allows either of the two modules to used as a mono signal (LMono, Rmono) or the two together as a stereo signal (STEREO). In the �rst two cases, the balance control effectively acts as a pan control). The second control, set using the POD 3 encoder, controls the width of the stereo image created by the two controls from a mono point source (center) to a stereo (counterclockwise) image. Turning the pointer clockwise from the center reverses the left and right channels.

Use the POD 4 encoder to switch between milliseconds and samples as the units in which the delay time is set and displayed.

Digital trim Allows the module�s input to be
adjusted. This is post-phase and pre-gate. It is entirely independent of the analog TRIM controls on the mic/line inputs. The value of this digital trim can be adjusted from a cut of �50dB to a boost of +10dB in 0.5dB steps. Also see �Phase/trim/delay� on page 84 below.

Dithering (stereo buss module only) When
going from 24-bit to 16-bit, using dithering is often a good way of reducing noise, etc. The POD 2 encoder can be used to set dithering Off (24-bit) or to the 16bit (On) setting. The exact form of bit-reduction used can be set here as well as in the DIGITAL FORMAT screen (see �Digital I/O setup� on page 51): TRUNCATE, DITHER and NOISE SHAPED.

Pan and balance settings Many of these settings are dependent on whether the channel being

Phase/trim/delay Phase The phase of an input signal, as explained
above, can be set either to normal or reversed. Use the ASSIGN PARAMETERS screen (�Global module settings� on page 72) to view and set the phase for all input at once.
