Initial Setup
:
When first connecting your LUNCHBOX
Acoustic
, before power is applied, please be sure to set
the controls as follows:
• REVERB set to off. (Fully counter-clockwise.)
• BASS set to mid-point. (12 o’clock position.)
• TREBLE set to mid-point. (12 o’clock position.)
• VOLUME set to off. (Fully counter-clockwise.)
• GAIN set to mid-point. (12 o’clock position.)
• FEEDBACK CUT set to off. (Fully counter-clockwise.)
• SPEAKER switch on rear panel set to “Internal” position. (Towards left side.)
• Now you can apply power, and turn up your instrument and/or microphone to the desired
level using the VOLUME knob.
Gain and Volume:
Normal adjustments to the sound level should be made using the master VOLUME control only.
This knob affects the signal levels going into the LUNCHBOX
Acoustic’s
high-power amplifier. It
does not affect the electrical level at the EFX SEND jack, but will affect the sound level of all other
outputs (Internal or External Speaker, and Headphones).
The GAIN controls are used to set the input sensitivity of each channel. In most cases, these
controls should be set high up, generally above the 50% point of their ranges. This will assure a
good tone, and low operating noise. Of course, you might have to adjust the GAIN controls to feed
your favorite effects properly.
The key to low noise is to keep the GAIN knob high, and use the VOLUME knob to adjust your
sound level.
Bass and Treble:
The LUNCHBOX
Acoustic
features separate BASS and TREBLE controls for Instrument
and Microphone channels. At ZT, we don’t take these features lightly. We studied classic and
modern tone controls, noting each one’s strengths and weaknesses. In the spirit of the original
LUNCHBOX amp, the LUNCHBOX
Acoustic
provides an extraordinarily wide palette of tones
using simple controls, giving you quick access to just the sound you seek.
Reverb:
The LUNCHBOX
Acoustic’s
REVERB effect is a traditional plate style reverb that simulates the
echo and decay of sound reflections in a room or hall. You can adjust the amount of REVERB
on both the Instrument and Microphone channels from the top panel. ZT’s proprietary dynamic
processing handles other sonic features as you play, but we give you the flexibility to separately
control this primary sonic flavor.
