Page 4: Powering Alexa
Powering Alexa DC Input: Alexa powers with a 9Vdc regulated, center-negative power supply that can supply 100mA or more, such as a BOSS PSA power supply. Exp / Tap Getting Connected (Mono) Input: Plug the cable from your guitar into here, or from the previous effect’s output. -
Page 5: Getting Connected (Stereo)
WARNING: The true bypass feature is dedicated for the left output only. When using Alexa in stereo, please set the pedal to buffer bypass, which is located on a switch on the inside of the pedal. When turning the effect off in true by- pass, the Right channel is disconnected from the input. -
Page 6: Selecting Buffer Bypass / True Bypass
When turning off the pedal, the outputs can receive a buffered signal (buffer bypass) of the input, or the left mono output can receive a non-buffered signal (true bypass) of the input. An internal slide switch determines whether Alexa uses buffer bypass (labeled BUF) or true bypass (labeled TRU-BYP). -
Page 7: Channel Selection / Bypass
Channel Selection / Bypass Alexa has two channels (green and red) with independent settings that are selected by the switch labeld A/B [2]. The channels can be set for the same sound on each channel with slight modifications, or they can be radically dif- ferent. -
