- Bass In: 1/4" TS input jack for connecting your bass guitar.
- Normal/PAD -12dB Switch: Selects input sensitivity. Use "PAD -12dB" for active basses with high output to prevent clipping.
- Telefoni: 1/8" TRS stereo output jack for connecting headphones.
- Aux In: 1/8" TRS stereo input jack for connecting external audio sources like an MP3 player or smartphone for practice.
- Bass Thru: 1/4" TS output jack for sending the unprocessed bass signal directly to another amplifier or device.

Figure 2: Top panel of the Palmer POCKET AMP BASS, displaying the various knobs and switches for tone shaping and effects.
- MODE Switch (Fuzz, O.DRIVE, CLEAN): Selects the primary sound mode.
- PULIZIA: Provides a transparent, uncolored bass tone.
- O.DRIVE: Adds a warm, natural overdrive.
- FUZZ: Delivers a thick, aggressive fuzz effect.
- Manopola DRIVE: Adjusts the amount of gain or distortion for the O.DRIVE and FUZZ modes.
- BLEND Knob (Dry/Wet): Mixes the direct (dry) signal with the processed (wet) signal. Fully counter-clockwise is 100% dry, fully clockwise is 100% wet.
- SATURATE Knob: Controls the saturation and compression characteristics of the tone.
- Manetta VOL: Adjusts the overall output volume of the unit.
- F.SW Switch (MUTE/BYPASS): Controls the footswitch function.
- MUTE: Footswitch mutes the output.
- BYPASS: Footswitch toggles between active effect and true bypass.
- CAB Switch (FLAT, MODERN, VINTAGE): Selects the cabinet simulation type.
- PIATTU : No cabinet simulation, providing a raw, direct sound.
- MUDERNU: Simulates a modern bass cabinet with full-range response.
- VINTAGE: Offers a warmer, more colored sound reminiscent of classic bass cabinets.
- Manopola BASS: Adjusts the low-frequency response (EQ).
- LEVEL Knob (Mid EQ): Adjusts the gain/cut of the selected mid-frequency.
- FREQ Knob (Mid EQ): Selects the center frequency for the semi-parametric mid-range EQ.
- HIGHS Knob: Adjusts the high-frequency response (EQ).
- Pedale: Engages/disengages the effect or mutes the output, depending on the F.SW setting.

- DI Out (Balanced XLR): Balanced XLR output for direct connection to a mixing console or audio interface.
- PRE/POST Switch: Determines whether the DI output signal is taken before (PRE) or after (POST) the internal effects and EQ.
- Interruttore GND/LIFT: Ground lift switch to eliminate hum caused by ground loops.
- À AMP (1/4" TS): Unbalanced 1/4" TS output for connecting to a bass amppiù vivu.
- FX Insert (1/4" TRS): Stereo 1/4" TRS jack for connecting external effects pedals in a send/return loop. Tip is Send, Ring is Return.
- DC 9V (200mA, Center Negative): Power input jack for a 9V DC power adapter.
Istituisci
- Cunnessione di putenza: Connect a 9V DC, 200mA, center negative power adapter (not included) to the "DC 9V" input on the rear panel. Alternatively, the unit can be powered by a 9V battery (located in the compartment on the bottom).
- Cunnessione di u strumentu: Plug your bass guitar into the "Bass In" jack on the front panel. If using an active bass with high output, set the "Normal/PAD -12dB" switch to "PAD -12dB".
- Cunnessione di Output:
- For headphones: Connect headphones to the "Phones" jack.
- Per un amplifier: Connect the "TO AMP" jack to your bass ampl'input di u lifier.
- For a mixing console/audio interface: Connect the "DI Out" XLR to the console/interface. Adjust the "PRE/POST" and "GND/LIFT" switches as needed.
- Entrée auxiliaire : To play along with external audio, connect your audio source (e.g., smartphone) to the "Aux In" jack. The volume of the auxiliary input is controlled by the source device.
- Ciclu d'effetti (opzionale): To integrate external effects, connect a TRS cable from the "FX Insert" jack to your effects pedal(s). The Tip of the TRS cable is the Send, and the Ring is the Return.
Istruzzioni di funziunamentu

- U MISCELA knob allows you to mix your original clean bass signal with the processed signal. This is particularly useful for retaining low-end clarity when using distortion effects.
Equalizzazione (EQ)
- U Bass knob boosts or cuts low frequencies.
- U ALTE knob boosts or cuts high frequencies.
- The mid-range EQ is semi-parametric:
- Aduprà u FREQ knob to select the specific mid-frequency you wish to adjust.
- Aduprà u LIVELLU knob to boost or cut the selected mid-frequency.
Cabinet Simulation
- U CAB switch allows you to select between three different cabinet simulations:
- PIATTU : Bypasses cabinet simulation.
- MUDERNU: Provides a clear, full-range sound typical of modern bass cabinets.
- VINTAGE: Offers a warmer, more colored sound reminiscent of classic bass cabinets.
Footswitch Functionality
- Pone u F.SW switch to either MUTE or BYPASS to define the footswitch's action.
- Press the footswitch to activate the selected function.
Mantenimentu
- Pulite l'unità cù un pannu dolce è asciuttu. Ùn aduprate micca detergenti abrasivi o solventi.
- Evitate d'espone l'unità à temperature estreme, umidità o luce solare diretta.

Risoluzione di prublemi
| Prublemu | Causa Possibile | Soluzione |
|---|---|---|
| Nisuna uscita di sonu. | Incorrect connections, low battery, footswitch in MUTE mode, volume too low. | Check all cable connections. Replace battery or connect power adapter. Ensure footswitch is not in MUTE mode. Increase VOL knob. |
