Fig. 3.1: BVT4500H/BVT5500H rear panel

This chapter describes how to use the rear panel of the BVT4500H and the BVT5500H, which includes the same features. Figure 3.1 illustrates these features.

++ To effectively use the jacks on the rear panel, you need to know about the BVT signal path. For details, refer to the secion “THE SIGNAL PATH”.

(21)Serial number: To register your unit, you will need this unique identifier.

(22)Fuse compartment: For details about the appropriate fuse type, refer to the “SPECIFICATIONS”. See also chapter

1.1.2. Replace this fuse only with the type specified for your country.

(23)Power connector: To power the BVT4500H/5500H, plug the power cord in this AC connector. The power cord comes with the BVT.

++ Attention: The POWER switch does not fully disconnect the unit from the mains. Unplug the power cord completely when the unit is not used for prolonged periods of time.

(24)Fan: This fan prevents the BVT4500H/5500H from overheating.

++ Do not block the ventilation openings that cover the fan.PARALLEL SPEAKER OUTPUT

Via the following jacks, you can simultaneously connect up to 3 speakers directly to the BVT:

(25)Two ¼" TS (mono, unbalanced) jacks.

(26)A single Neutrik Speakon compatible jack, for high-power loudspeakers. The pin designation of the speaker is pins 1+ and 1-. For details, refer to the chapter “AUDIO CONNECTORS”.

If you use a single speaker or a high-power speaker, connect this speaker to the Neutrik Speakon compatible jack. To prevent electrical shock and ensure the correct polarity, this jack locks an audio plug in place.

++ Before you connect speakers to the BVT4500H/5500H, turn it off.
