Fig. 5.1: BVT5500H setup example

In the above example,

== a speaker (ULTRABASS BA810), == a mixer (XENYX 1832FX),

== and a tuner (RACKTUNER BTR2000)

are simultaneously connected to the BVT5500H.

However, you can tune without adjusting the speaker volume. For details, see “FRONT PANEL” (MUTE button {8}) and “REAR PANEL” (TUNER jack (35)).

The audio signals that the ULTRABASS BA810 and the XENYX 1832FX receive from the BVT5500H are not the same:

== The ULTRABASS BA810 receives a fully amplified signal.

== The XENYX 1832FX receives a preamplified (line-level) signal.

You can select the type of preamplified signal (PRE or POST TONE/EQ/EFFECTS) that the BVT5500H sends. For details, see

“THE SIGNAL PATH”.

6. The signal path

This section provides what you need to know to effectively use the BVT control elements and connection jacks. For an overview of the possible paths your signal may take, refer to the illustration in the section “SYSTEM BLOCK DIAGRAM”.

In general, the signal path of the BVT can be split into two phases:

1)Pre-Amplification, which starts at the INPUT jack ({3},{5}) and ends immediately at the PREAMP OUTPUT jack (28).

2)Power amplification, which starts at the POWER AMP IN jack (27)and ends at the PARALLEL SPEAKER OUTPUT jacks ((25),(26)).

Note that only the PARALLEL SPEAKER OUTPUTs carry a fully amplified signal while the other output jacks carry line-level signals.

The rest of this section covers all BVT jacks and ways to connect your equipment to them.

6.1 INPUT

PURPOSE: To send an audio signal from an electric bass to the BVT.

RESULTS: The signal path begins at the INPUT jack.

6.2 TUNER

PURPOSE: To send a copy of an audio signal from the BVT to an electric tuner.

RESULTS: The main signal path is not affected. If you use the:

== BVT4500H, you can reduce the volume of the PARALLEL SPEAKER OUTPUTs or use the mute feature on your tuner. For details, see TUNER jack (35).

== BVT5500H, you can mute the PARALLEL SPEAKER OUTPUT s and the LINE OUTPUT. For details, see MUTE button {6}.

6.3 LINE OUTPUT

The characteristic of the signal at the LINE OUTPUT jack depends on the state of the PRE/POST switch.

6.3.1 PRE

PURPOSE: To send a copy of an audio signal to a mixer or a recording unit without any preamp settings (TONE, EQ, EFFECTS). See also section 6.3.2.

RESULTS: The main signal path is not affected.

6.3.2 POST

PURPOSE: To process an audio signal with all BVT preamp features (TONE, EQ, EFFECTS), and then send the preamplified signal to a mixer or, alternatively a recording unit.

Notice that the LINE OUTPUT jack (with POST) derives the signal before the MASTER control. This means the output level of this jack is independent of the actual amplifier volume.

Keep in mind that you can activate and deactivate the EQ sec- tion. In addition, the BVT4500H and BVT5500H do not process external effects in the same way. For details, see the section “EFFECTS LOOP”.

RESULTS: The main signal path is not affected.
