Chapter 4 Designer Device group 1 DME64N Unit No.1 OUT IN DME64N Unit No.2 OUT DME64N Unit No.1 OUT IN DME64N Unit No.2 Device group 2 IN DME64N Unit No.3 OUT DME64N IN Unit No.4 NOTE When multiple DME64N units are cascade connected, each additional unit introduces a delay of a few samples that is automatically compensated for. The Unit No. settings determine the amount of automatic compensation to be applied for each unit. Head Margin Sets the CASCADE bus signal head margin. This setting only applies when the unit is cascade connected to a mixer. Since Yamaha provides a CASCADE bus head margin of 18 dB, this parameter should normally be set to "18dB". The margin for cascade connected DME64N units is always "18dB" regardless of the setting. The head margin settings for DME64N units other than the first unit are automatically set to the same value as the first unit when cascade connections are made, and are thereafter grayed out and can't be changed. No head margin is provided when a cascade connected PM5D is set up to send the slot output signals via its CASCADE OUT terminal, so the Head Margin parameter must be set to "0dB". Mixer I/O Channel Determines whether a direct cascade connection between a DME64N unit and mixer will be bidirectional (bus sharing) or not on a channel-by-channel basis. Make sure that the checkboxes for cascade connected DME64N units are all set the same. The settings are matched automatically when DME64N units are connected via their [CAS IN] and [CAS OUT] terminals in the Zone window. OFF: The connection with other DME64N units is bus sharing bidirectional. Since the mixer does not support bidirectional connection the connection between the mixer and DME64N unit is unidirectional CASCADE IN -> CASCADE OUT, regardless of the checkbox setting. ON: The connection with other DME64N units is unidirectional CASCADE IN -> CASCADE OUT. For DME64N units connected between two other DME64N units the connection is internally set to bidirectional, regardless of the checkbox setting. NOTE The following settings are made automatically when cascade connections are made, regardless of the checkbox setting. • DME64N unit between two other DME64N units: bidirectional. • DME64N between two mixers: unidirectional. • One mixer connected to one DME64N unit: unidirectional. 222 DME Designer Owner's Manual
