The Speakeasy v4BT is a self-contained, battery-powered speaker with mic, line and instrument level inputs, and an integrated Bluetooth receiver for wireless playback of audio. It is housed in a cast aluminum enclosure with a durable black finish and features an improved audio signal path and upgraded power amplifier for better clarity and faithful sound reproduction.The Speakeasy v4BT drivers are magnetically shielded, allowing operation near sensitive equipment.
The Speakeasy v4BT will operate on two 9V batteries, typically for a full day of intermittent use. It will also operate from an external 9 - 18VDC power source on its coaxial power connector (2.1 x 5.5mm, center pin positive). The internal battery is switched out of circuit when plugging in external power so there is no need to remove the battery when using external power.
Line Level Input
The line level input is for balanced signals of +4dB, though unbalanced signals may be used. An XLR / 1/4" TRS combo jack is provided for convenience, and is wired in the standard balanced configuration of Pin 1/Sleeve = Ground, Pin 2/Tip: Audio Hot (+), Pin 3/Ring: Audio Cold (-).
Microphone Level Input
The XLR mic level input will accept a balanced mic level signal, and will directly accommodate a dynamic microphone. Powering for condenser mics is not available. The microphone input has 40dB of gain available, accessible on the rear panel with a small flat-bladed screwdriver.
Instrument Level Input
The Speakeasy v4BT will accommodate an unbalanced instrument-level signal on a 1/4" TS connector. The impedance of this input is 1Mohm, which is suitable for use with passive electric guitar pickups or active guitar preamp systems without "loading down" the pickups and causing high frequency roll-off. Instruments with very hot outputs, such as electric guitars with overwound humbucker pickups, may cause distortion. In that case, the guitar's volume control should be adjusted to minimize distortion.
All audio inputs are isolated from each other and therefore may be used at the same time. For example, a line level input can be used for music playback while the mic input is used for cueing.
The Speakeasy v4BT is equipped with a built in bluetooth receiver module for wireless audio playback. It has a range of over 30 ft. depending on the environmental factors. It features a simple two button interface with two status LEDs.
