Reverb Level –
An optional remote switch box for steel guitar (and a remote foot switch for other
Rev ON button
instruments) is available for rapid remote control of the TBro and Reverb
functions. The usage of these optional accessories is outlined later in this manual.
(continued)
A TRS three-conductor coaxial cable is necessary to connect most multi-effect
units to an external control box or foot pedal.
This fader controls the ratio of "dry" (without effects) and "wet" (with effects)
DRY/WET Fader
signals sent to the Master Level control. Counter clockwise is dry, clockwise is
wet.
DRY/WET FADER – EFX SEND + LEVEL (rear panel) - EFX
RETURN + LEVEL (rear panel) – The Dry/Wet Fader and rear panel
effects loop is a very powerful feature that allows effects to be added to
the analog signal chain in a number of ways.
The level sent out to the effects unit can be adjusted using the EFX Send
Level on the rear panel. This is adjustable to drive effect inputs from, -
30dB to +4dB ; the +4dB setting generates the highest output. It's very
important to ensure the TCA-500 Overload LED just starts to blink
BEFORE the effects processor input level reaches its maximum input
level or clipping point. The average user can easily ensure the correct
and proper EFX send level by looking up the preferred level in the
manual for the appropriate multi-effects units and setting the EFX
RETURN and EFX SEND controls on the TCA-500 to specified levels.
Normally these levels will be -10 dBu, -8 dBu, -4 dBu, 0 dBu or +4
dBu. The TCA-500 provides the ability to match virtually any high
quality EFX units.
The level returned from the effects unit can be reduced or boosted using
the EFX Return Level on the rear panel. This is adjustable over the
range from, -30dB to +4dB ; the +4dB setting applies the highest gain
to the returned signal. This level should be adjusted so the effects
processor output doesn't cut or boost the signal; we call this 'unity'
gain. A good way to check this is to set the effects processor to
'bypass': Then set the DRY/WET Fader fully Wet and then fully Dry,
you should notice virtually no change in volume; adjust the EFX Return
Level to achieve this.
