Effects Send
This jack’s primary function is to send a
1.A line level output for use in conjunction with an additional (slave) power
2.An unbalanced output suitable for recording or live mixing board purposes.
The output impedance of the Effects Send jack is 100 Ohms.
Effects Receive
This jack’s primary function is to complete the Effects Loop circuit by routing the
1.A power amp input jack. If, for some reason, you wished to bypass the entire front end and use the 350x strictly as a power amp, you could take the output of whatever
2.An input for
Input impedance of the Receive jack is 27k Ohms minimum.
Note: Inserting a plug into the Effects Receive jack activates the Effects Blend control. The con- trol receives this command through the ground created by the phone plug making contact with the jack. The plug must be a mono plug (tip and ground). If you have a stereo plug only, it will be nec- essary to tie the ring and the ground together.
SubWave™ Activator Footswitch
Your 350x comes equipped with the capability for
Note: The type of switch contained inside the footswitch chassis is momentary, normally open. If you connect the footswitch to the unit while the unit is on, the SubWave effect may engage. This is normal.
Cooling Fan & Fan Mode Switch
The power amp in your 350x is cooled by two methods: 1) An (internal) extruded aluminum heatsink; and
2)A thermostatically controlled fan. This fan turns on when the heatsink reaches 50 degrees centigrade and turns itself off when the heatsink reaches
Setting the Fan Mode Switch to the “Fan” position activates the internal cooling fan’s normal operating mode as described above. Setting the switch to the "Defeat” position deactivates the cooling fan regard- less of the internal temperature of the unit. For this reason, it is recommended that the Fan Mode Switch be set to the “Fan” position for the majority of the time that the amplifier is in operation.
Note: It is normal for the cooling fan to be audible at low levels. We recommend deactivating the fan only in situations where the noise floor is so low that normal fan noise might be noticeable or distracting, such as recording situations where a microphone is used in close proximity to the unit.
