H9 User Guide Bypass

Bypass

It’s important to select the Bypass function that works best with your setup. The

H9 gives you the choice of Bypass type – DSP Bypass, Relay Bypass or DSP+FX

Bypass. The H9’s default Bypass setting is DSP Bypass.

DSP Bypass

When set to DSP Bypass, bypassing sends the audio at the DSP’s inputs directly to

the outputs without any effects processing. This type of bypassing works well in

most situations, and protects against gain and tone changes when bypassed.

Relay Bypass/True Bypass

Some guitarists prefer a “true bypass” in which the pedal’s electronics are

completely disconnected from the signal path. When [RELAY] Bypass is selected

the H9 uses relays to “hard wire” your inputs to your outputs. (In fact, whenever

the H9’s powered down, its electronics are completely bypassed by the relays.)

Relay Bypass is not a good choice if the H9’s input is your guitar and you’ve

connected the H9’s output directly to a non-instrument level input device or have

connected to your amp over a long cable. Non-instrument inputs are often low

impedance (typically <10k ohm) and will load the guitar output and change its

tone. DSP Bypass allows the H9 to act as a buffer, providing a low impedance

output (500 ohm) capable of driving any device input or cable length.

DSP+FX Bypass

When [DSP+FX] is selected, Bypass sends the audio at the DSP’s inputs directly to

the outputs with the decaying ‘tail’ of the current effect mixed in.

Selecting Bypass Type

The Bypass mode is selected in System Mode under [BYPASS]. [DSP] is the default.

Here’s how to change it:

1) Press and hold the HOTKNOB button and Right Footswitch

simultaneously for a few seconds to enter System Mode.

2) Turn the Knob until [BYPASS] is displayed.

3) Momentarily press the HOTKNOB button.

4) Turn the Knob until [BYPTYP] is displayed.

5) Momentarily press the HOTKNOB button.

6) Turn the Knob to select [DSP] or [RELAY] or [DSP+FX].

7) Press and hold the HOTKNOB button and Right Footswitch

simultaneously for a few seconds to exit System Mode.
