ULTRABASS BVT4500H/BVT5500H

6.4 EFFECTS LOOP

The EFFECTS LOOP section can be used in three ways:

6.4.1 SEND and RETURN

PURPOSE: To create an effects loop, i.e., to apply external effects to the signal.

RESULTS: If you use the:

== BVT4500H, only the audio signal that enters via the RETURN jack continues to follow the BVT4500H signal path. The level of the effects has to be adjusted on the external unit.

== BVT5500H, both the main audio signal and the audio signal that enters via the RETURN jack follow the BVT5500H signal path. To adjust the dry-wet mix, use the EFFECTS MIX control.

6.4.2SEND only (BVT5500H only)

PURPOSE: To send an audio signal from the BVT5500H to an effects processor.

RESULTS: The main signal path is not affected.

6.4.3 RETURN only

PURPOSE: To send an audio signal from an external pre-amp to the BVT4500H/5500H, i.e., to use the BVT as a power amp only.

RESULTS: If you use the:

== BVT4500H, the INPUT jack is deactivated. The signal path begins at the RETURN jack.

== BVT5500H, the INPUT jack remains active. You could e.g., connect two basses to the BVT, one to INPUT and the other to RETURN. To adjust the balance between the two, use the EFFECTS MIX control.

6.5INSERT CHANNEL
6.5.1PREAMP OUTPUT

PURPOSE: To process an audio signal with all BVT preamp features (TONE, EQ, EFFECTS), and then send the audio signal to an external power amp. The BVT settings affect the volume on the external amp.

RESULTS: The main signal path is not affected.

6.5.2 POWER AMP IN

PURPOSE: To process an audio signal with an external preamp, and then send the audio signal to the BVT4500H/5500H power amp.

RESULTS: The signal path begins at the POWER AMP IN jack. The signal is independent of the MASTER control.

++ Switch off the unit before connecting an external preamp to POWER AMP IN.

7. Audio connectors
